1. Sulphur powder is the best soil conditioner

For high polymer soil amendments, such as polyacrylamide, it can absorb water and expand when applied to the soil in its solid state, but it is difficult for the structural amendment to dissolve into the soil solution. When it is dissolved in water and applied, soil physical properties can be significantly improved.

Therefore, most of the water-soluble soil conditioner sulfur powder is currently used, and the technical methods of spraying and irrigation are mostly used. However, for the greening and improvement of large deserts and deserts, due to the limitations of water and other conditions, spraying and irrigation techniques are difficult to apply.

The soil conditioner should be applied when the topsoil moisture is suitable, and the best effect is when the soil moisture is 70%-80% of the maximum water holding capacity of the field. In recent years, due to the improvement of application methods from solid application to liquid application, the requirements for soil moisture during application are different than before.
Increasing soil organic matter can play a dual role of improving soil physical properties and increasing soil nutrient content. However, the source of organic fertilizer is limited, and it is difficult to meet the requirements. However, soil amendments can be synthesized artificially and have a wide range of sources. It is feasible to use them to replace organic matter to improve soil. The simultaneous use of the two can not only improve the soil structure, but also make up for the lack of organic matter sources.
A large amount of long-term application of chemical fertilizers is likely to cause soil compaction, deterioration of physical and chemical properties, and soil pollution. Soils with poor structure and low fertility are not as effective as soil amendments or fertilizers alone. When used at the same time, the output can be significantly improved. 

2. Sulfur powder is an effective pesticide in agriculture

As an effective disinfectant, sulfur powder is widely used in agriculture and daily life, especially in the planting industry. At present, many fertilizers are added with an appropriate amount of sulfur powder, so that fungal spores and mites can be effectively repelled after fertilization, thereby protecting the growth of agricultural products.

Sulfur powder is a kind of multifunctional medicament with good bactericidal effect. According to the survey of sulfur powder manufacturers, many consumers now use it to control powdery mildew and leaf mites of various crops, and the lasting period can reach about half a month. Vegetables use sulfur gum suspension, which is mainly used to control melon powdery mildew, such as cucumber, muskmelon (cantaloupe), pumpkin, etc. When using, dilute the 50% sulfur colloidal suspension into 200-400 times liquid spray. Spray once every 10 days or so, generally 2 times for mild cases and 3 times for severe cases. The control effect of the sulfur powder manufacturer's preparation is closely related to the temperature. In the high temperature season in summer, the concentration should be low, and 400-500 times of the liquid should be sprayed to avoid phytotoxicity.

For the majority of growers, sulfur powder is a very useful disinfectant, but it also needs to be understood and learned before using it to avoid the opposite effect.

3. The function of cutting base dipped in sulfur powder

Sulfur powder is an acidic compound. It is used on flowers and plants, forest trees and fruit trees. It has the functions of sterilization and antisepsis, regulating acidity and alkalinity, promoting wound healing, preventing and controlling diseases and insect pests, and can also provide plant nutrients and promote growth and development. What are the effects of dipping the cutting base with sulfur powder?

Prevent injury. Plants that are prone to bruising, such as the roots, branches and leaves of figs, grapes, banyan trees, cycads, etc., smear sulfur powder on the wound after pruning, which can inhibit bruising, prevent wound infection and rot, and promote healing.

Prevent root rot. If Clivia often has rotten roots due to excessive watering or unclean culture soil, you can knock it out of the pot, remove the culture soil, cut off the rotten roots, rinse the roots with water, and let them dry for a while, while the roots are slightly moist. , spray sulfur powder, and then plant with sterilized culture soil, and new roots will grow in about a month; if the roots are completely rotten, they can be planted in plain sand after spraying sulfur powder. After it grows new roots, it is cultivated with sterilized culture soil. When the rotten roots of the big tree turn yellow, the root soil should be cut open, the rotten roots will be cut, and the roots should be sprinkled with sulfur powder and covered with fresh sterile soil, which can prevent the rotten roots from continuing and restore normal growth.

Prevent cuttings and flower arrangements from rotting. When camellia, rhododendron and other forest fruits and flowers are raised by cuttings, dipping the base of the cuttings with sulphur powder and then cuttings can effectively prevent the cuttings from rotting and greatly improve the survival rate. Dipping the base of the flower arrangement with sulfur powder can prevent the cuttings from rotting, reduce the decay rate, and prolong the viewing period of the flower arrangement. For example, the cuttings of camellia and rhododendron are dipped in sulfur powder and directly inserted into the pine leaf humus sterilized with potassium permanganate, and the survival rate can reach more than 90%.

Control flowers, trees, melons and fruits that are prone to powdery mildew. Apply sulfur powder when the leaves are wet or dewy, and spray with sulfur powder suspension or lime-sulfur mixture in dry weather, which has special effects on the control of powdery mildew.

Anti-saline hazards. In the waterlogged and hardened saline-alkali soil, a certain amount of sulfur powder can be applied to adjust the pH value of the soil, reduce the salinity, and promote the normal growth of fruit and flowers.

Anti-marriage interface rot. Grafting and raising seedlings of succulent plants, such as grafting crab claw orchid with cactus, spraying sulfur powder on the grafting interface and then preventing rain and sunshade can inhibit bacterial infection, prevent rot, and improve the survival rate of grafting.

4. Sulphur powder adjusts the soil with high PH of blueberry

Too high soil pH is a major factor limiting blueberry cultivation. Too high pH often causes blueberries to lack Fe and chlorosis, reduce yield, and even plant death. When pH is greater than 5.5, measures should be taken to reduce soil pH. The most common method is soil application of sulfur powder (200 mesh).

Application method of sulphur powder: evenly spread the sulphur powder on the ground according to the calculated application amount, and dig about 30cm deep by hand or machine, so that the sulphur powder and the soil to be improved are evenly mixed. The application of sulfur powder should be carried out one year before the planting, and the effect in that year is not obvious. The improvement effect of the whole garden is the best. In order to reduce the cost, planting ditch improvement or planting hole improvement can also be adopted. Lowering pH is usually done in conjunction with other soil improvement measures such as increasing organic matter. Therefore, the method commonly used in China is the improvement of planting ditch, or the improvement of planting hole. In addition to adjusting soil pH with sulphur powder, the incorporation of acidic peat moss is also effective in lowering soil pH. Peat moss mixed with sulphur powder is more effective. In addition, soil mulching with sawdust, pine bark, application of acidic fertilizers, and application of crude tannic acid all have the effect of lowering soil pH.​​

5. The preparation of sulfur powder can prevent the occurrence of diseases and insect pests in flowers and trees

Sulfur powder is very useful in agriculture, especially in plant cultivation. Now let's introduce how to prepare sulfur powder by yourself for planting flowers and trees.

1 to 2 weeks before planting or planting of flowers and trees, evenly pour 3 to 4 kg of sulfur powder into the soil of the flowerbed per mu, which can inhibit the reproduction of various pathogenic bacteria and have a certain effect on the prevention and control of diseases in the seedling stage of flowers and trees. .

Fumigant. Mix 200 grams of sulfur powder with 400 grams of dry sawdust (add chlorothalonil powder or dichlorvos EC, etc.) to make aerosols, which are used for fumigation in flower houses or greenhouses to control powdery mildew, aphids and whiteflies in greenhouses. main pests. Usually fumigation work should be carried out before flowering.

Lime sulfur mixture. Mix 0.5 kg of quicklime and 7.5 kg of water into milk of lime, then slowly pour 1 kg of sulphur powder into the milk of lime, stir quickly while pouring to make it evenly mixed, then place the mixture in a clay pot or Heat it in an iron pot until it boils and continue to boil for 50 to 60 minutes. When the mixture turns reddish-brown, the filtrate after filtering out the dregs is the mother (original) liquor of the lime sulfur mixture of about 25 Baume degrees (Note: can not be used Boil or serve in copper or aluminum containers).

White paint. Add 0.5 kg of lime sulphur mixture stock solution (or sulphur powder) to the lime slurry prepared by 5 kg of quicklime and 20 kg of water, then add 0.5 kg of salt and 0.1 kg of animal and vegetable oil, and stir well White paint (also known as whitening agent). In early winter, it is used to paint the stems of flowers and trees, which can not only prevent diseases and insects that overwinter in the cracks of the stems and bark of flowers and trees, but also protect the stems of flowers and trees from frostbite and sunburn.

6. Sulfur powder can prevent the occurrence of diseases and insect pests in fruit trees

In agriculture, sulphur powder is very useful, it can prevent the occurrence of insect pests in flower and fruit trees. Here we will introduce how to apply sulphur powder to prevent insect infestation in fruit trees.

When watering fruit trees, you can mix an appropriate amount of sulfur powder into the water, so that after fully stirring, spraying the trunk and roots of the fruit trees can play the role of pest control.

Fruit tree sulfur powder can be directly buried in the roots of fruit trees with other antibacterial drugs. Many diseases and insect pests of fruit trees occur at the roots. After preparing a certain proportion of sulfur powder, directly dig soil along the crown and strong roots of fruit trees with shovels to bury them. The depth should be changed according to the size of the fruit tree, and the dosage should be well controlled to prevent too much seedling burning.

When the fruit tree sulfur powder is used to disinfect vegetable greenhouses, it can be closed and burned for disinfection. Place the fruit tree sulphur powder in the greenhouse vegetables and ignite it with an open flame. When burning, be sure to seal the greenhouse vegetables. In addition, there must be no living objects in the shed, so as to avoid the sulfur dioxide gas caused by combustion, which will cause damage to living beings.

7. Sulfur powder can prevent powdery mildew

(1) Powdery mildew is a common disease of Chinese roses. In an environment with high temperature, high humidity and poor ventilation, an oily and powdery substance appears on the surface of stems and leaves. At this time, the plant stops growing and the flower buds are not easy to open. . In severe cases, the leaves will dry up and fall off, and start to shrink downward from the new shoots. This is powdery mildew. The use of sulfur powder to control the disease is very effective. Specific method: first wet all the diseased plants with water, roll a small tube with paper, put 1 to 2 grams of sulfur powder into the paper tube, blow out the sulfur powder against the diseased plants, and sprinkle them evenly on the plants superior. Then, choose another angle to do the same, so that the stem, leaf surface and leaf back of the diseased plant are attached with sulphur powder. After 2 to 3 days, the oil powder can disappear. If the number of cultivation is large, it can be sprayed with a duster. 

(2) First use a sprayer to wet the diseased plants (to facilitate the adhesion of sulfur powder), and then use a powder sprayer to spray the sulfur powder on the diseased branches and leaves, and spray less on the unaffected branches and leaves (for prevention). effect). After a few days, the powdery mildew was gone. For powdery mildew that occurs on potted flowers, wash the original Guilin watermelon cream (medicine for oral ulcers) in a small watering can, dry it, and spray it with sulfur powder. It can also be used to roll thicker paper into a large paper tube, put a small amount of sulfur powder from the big end, aim at the diseased part, blow from the small end, and the sulfur powder will be scattered evenly.
