The role of potassium sulfate.

Effect one, raw material, potassium sulfate itself does not contain chlorine, Wu Rangzi is the main cavity of high-quality nitrogen, phosphorus and potassium ternary compound fertilizer essential raw materials, the annual amount in the market is also very large.

The second function is to apply Jingbi crops, because potassium sulfate is chlorine-free, so it is especially suitable for plants that are sensitive to chlorine, such as tobacco and grapes, potatoes, etc., and the effect is very good in increasing production and income.

Function 3, acid-base balance, potassium sulfate fertilizer has the effect of concealing acid-base balance, can improve the physiological activity of crops, promote the benign growth of crops, so as to increase the ability of plants to resist lodging and diseases and insect pests.

Fourth, improve the quality, crops in the late stage of growth, for example, melons and fruits have a large demand for nutrients, Tongxian Fan's reasonable nutrients can promote the uniform coloring of fruits, bright luster, hail can speed up the early maturity of plants, and win the early closing time.

How to use potassium sulfate.

Potassium sulfate is a fertilizer that can be used as chicken fertilizer, that is, base fertilizer, and top dressing, which is used during plant growth, as follows:

1.Bottom fertilizer, when applying bottom fertilizer to the soil, 8 10 kg of potassium sulfate fertilizer can be applied to one acre of land.

2.Top dressing, the potassium sulfocarate fertilizer is used as top dressing, mostly taking the method of foliar spraying, the concentration is between, and the specific proportion of water is 100 kg of water for the foliar spraying after dissolving the imitation stool.

There are four major ways of using potassium dihydrogen phosphate

1. Soak and mix seeds

Wheat dressing is about to begin. About 200g of potassium dihydrogen phosphate per mu, mixed with an appropriate amount of water, so that the solution is 7 cm higher than the seeds, soaked for 10 to 20 hours, and then sown after drying. The soaked seeds can also be mixed with acidic pesticides.

For example, if the seeds are mixed with potassium dihydrogen phosphate, 50kg of seeds should be mixed with water to 3 kg, and sprayed evenly on the seeds of Stuffy and plum with a sprayer, and turned in time. After spraying, the seeds are sown after 2 hours and dried. The treated seeds can promote the early emergence of seedlings, increase the number of roots and the number of sins, and make the plants grow robustly.

2. Irrigation and dipping roots

Irrigating roots with 1:1500 potassium dihydrogen phosphate solution can be used as a fast-acting phosphorus and potassium fertilizer, which can coordinate the effective use of nitrogen fertilizer, increase grain weight and increase yield.

Dipping the roots of crops with potassium dihydrogen phosphate aqueous solution can promote slow seedlings and easy rooting.

3. Foliar spray

Wheat, rice and other grain crops in the rejuvenation stage, booting stage, early flowering, grain filling stage each spray 1 time, each mu with about 200g of potassium dihydrogen phosphate, mixed with 30 kg of water, evenly sprayed on the crop stems and leaves.

Peanuts, soybeans, sesame, etc. in the flowering stage, pod-setting stage, and full fruit stage, spray with 50 grams of potassium dihydrogen phosphate each time, mixed with 15 to 20 kg of water;

Fruit trees, vegetables, melons and fruits, etc., in the flowering stage, young fruit stage, and fruit expansion stage, spray with 50 grams of potassium dihydrogen phosphate each time, mixed with 15 to 20 kg of water; It can promote plant metabolism, early maturity, enhance photosynthesis and chlorophyll content, promote grain fullness, improve fruit sweetness, drought resistance and high temperature resistance.

4. Bottom fertilizer

Apply 8 to 12kg of potassium dihydrogen phosphate per mu, with an appropriate amount of nitrogen fertilizer, and no longer apply phosphorus and potassium fertilizer. Potassium dihydrogen phosphate should not be applied before land preparation, but should be applied after land preparation and before sowing.

Summary. Hello, the pear tree fruit will turn fast on the potassium sulfate compound fertilizer.

Hello, the pear tree fruit will turn fast on the potassium sulfate compound fertilizer.

Potassium sulfate is a physiological mill and acidic fertilizer, so it should be properly applied with lime when applied on acidic soils. The combination of potassium sulfate and insoluble phosphate rock powder fertilizer can not only reduce acidity, but also improve the fertilizer efficiency of phosphate fertilizer. When potassium sulphate is applied on sandy soils, it can be applied in small amounts and multiple times, or in combination with farmyard manure to reduce fertilizer loss.

Hello dear! The high concentration of potassium sulfate compound fertilizer sprinkled under the fruit tree is insoluble, which will affect the fertilizer efficiency. Potassium sulfate is a high concentration of potassium fertilizer, if the residue sprinkled under the fruit tree is difficult to dissolve, it will lead to the release rate of potassium fertilizer will be slow, which will affect the fertilizer efficiency zone.

In addition, potassium sulphate is also acidic, and if it is used excessively or sprinkled under the fruit tree residue is difficult to dissolve, it will cause soil acidification, which in turn will affect the growth and yield of the fruit tree. Therefore, when using potassium sulfate compound fertilizer, attention should be paid to reasonable application to avoid excessive use and difficult dissolution of slag sprinkled under fruit trees.

A fruit tree can be fertilized with 50 grams of potassium magnesium sulfate.

The role and use of potassium magnesium sulfate fertilizer.

Potassium magnesium sulfate fertilizer, it is a multi-element potassium fertilizer, in addition to containing potassium, sulfur, magnesium, but also contains calcium, silicon, boron, iron, zinc and other elements, is weakly alkaline, especially suitable for acidic soil application, generally used as base fertilizer, can also be used as top dressing. It is suitable for rice, corn, sugarcane, peanut, tobacco, potato, sugar beet, fruits, vegetables, alfalfa and other crops. Compared with potassium chloride and potassium sulfate in the same amount of potassium (K2O), the application effect of potassium magnesium sulfate in agriculture is better than that of potassium chloride and slightly better than that of potassium sulfate.

Potassium sulfate magnesium fertilizer effect.

Potassium magnesium sulfate fertilizer is a natural mineral fertilizer, known as the "platinum potassium" of crop fertilization, and is a replacement for potassium sulfate. Using natural minerals containing potassium sulfate and magnesium sulfate, processed through several tedious processes, it is a natural green fertilizer that can provide comprehensive and balanced nutrients potassium, magnesium and sulfur for crop growth. On the basis of the function of traditional potassium sulfate products, magnesium is added, which greatly promotes the most important photosynthesis in the process of crop growth, magnesium plays a vital role in crop growth, it is the core component of chlorophyll, the growth of crops mainly depends on photosynthesis, and it is chlorophyll that plays a decisive role in photosynthesis.

Magnesium can also greatly promote the absorption of phosphorus by crops, promote the formation of crop growth enzymes, and then promote the formation of crop vitamins, carbohydrates, proteins and fats, and prevent early defoliation and fruit loss at maturity. Experiments show that potassium and magnesium sulfate fertilizer is suitable for all crops, especially for vegetables, fruit trees, tea and flowers and other cash crops, which can provide long-term stable fertilizer effect for the growth of crops, and can improve the quality of crops, enhance the ability of crops to resist drought, cold and pesticide damage, and the yield increase effect is very obvious.

How to use potassium and magnesium sulfate fertilizer.

Potassium magnesium sulfate fertilizer is suitable for rice, corn, sugarcane, peanuts, tobacco, potatoes, sugar beets, alfalfa and other crops, the dosage is slightly different according to different crops and different soil fertility, such as corn 10 to 26 kg mu, potato 22 to 37 kg mu, apple tree 18 to 36 kg mu, peach tree 24 to 105 kg mu, grapevine 6 to 31 kg mu, Chinese cabbage 7 to 43 kg mu, cauliflower 18 to 60 kg mu, etc.

Potassium is to promote the expansion of grape fruits, but for the potassium element of these **, potassium dihydrogen phosphate is the best, especially the powder potassium dihydrogen phosphate has high purity, only contains phosphorus and potassium, and the effect is good when sprayed on the foliar surface.

Top dressing is selectively fertilized according to the different phenological stages of the grapes. It can be divided into germination fertilizer, flowering fertilizer, fruit strengthening fertilizer and ripening fertilizer. The exact amount of fertilization should be based on the yield requirements of the tree and the fertility of the local soil.

Germination fertilizer: about February to apply a germination fertilizer, germination fertilizer is mainly nitrogen fertilizer, can use Yanwo water-soluble fertilizer nitrogen fertilizer, using furrow application or hole application.

Pre-flower: In late April, apply a pre-flower. Pre-flowering fertilizer, mainly nitrogen fertilizer and phosphorus fertilizer, with Yanwo water-soluble fertilizer high nitrogen and high phosphorus type, need to be watered immediately after fertilization.

Strong fruit fertilizer: Yanwo high potassium water-soluble fertilizer can be used, and furrow application or hole application is still used. The growth period of young fruits is the peak fertilizer demand of grapes in a year, and fertilization at this time not only promotes the growth of young fruits, but also has a good effect on the growth of branches and leaves of the year.

Coloring fertilizer: also known as ripening fertilizer.

Post-harvest fertilizer: After the fruit is harvested, due to the large nutrient consumption of the tree, fertilization is required to ease the tree and delay defoliation.

In recent years, with the improvement of grape fertilizer and water management technology, irrigation fertilization has been gradually adopted to replace traditional fertilization methods in production.

Top dressing begins in mid to late April, and fertilization is carried out using drip irrigation. 2kg of water-soluble compound fertilizer with nitrogen, phosphorus and potassium content of 15:15:15 can be applied per mu, which can be used at the same time as water-soluble fertilizer and water fertilizer, once a week, during which the soil is kept moist.

At the same time, during the grape growing season, according to the grape's nutrient requirements, topdressing can be carried out outside the roots. If the grapes are sprayed with foliar fertilizer after fruit set, they can continue to supplement nutrients, and Yanwo potassium dihydrogen phosphate can be used to supplement the phosphorus and potassium needs of the tree. 7-10 days after fruit harvest, it helps the plant to regulate growth, promote nutrient absorption, and restore the tree's vigor as soon as possible.
