Potassium is the main nutrient fertilizer(black plastic nursery pots). Potassium is involved in the activation of more than 60 enzyme systems, photosynthesis, transport of assimilated products, carbohydrate metabolism and protein synthesis during plant growth and development. Potassium fertilizers include potassium sulfate, potassium chloride, potassium dihydrogen phosphate, potassium nitrate, etc.(12.5cm plastic grow pots), and ash (the main component is potassium carbonate).(bulk buy plastic greenhouse plug plant trays)
It is used as a high-efficiency phosphorus-potassium compound fertilizer in agriculture(wholesale nursery pots). Potassium dihydrogen phosphate product is widely used in almost all types of crops such as various types of cash crops, food, fruits and vegetables. . The active ingredient content of potassium chloride is generally 50-60%, which is a physiological acid fertilizer(13cm plastic grow pots). It is forbidden to use in the coastal areas, and it is forbidden to use Fuji, Red Star and other varieties that are susceptible to manganese damage (apple apple skin disease).
(bulk buy plastic greenhouse plug plant trays)Potassium fertilizer is called potassium fertilizer(plug trays wholesale). Potassium sulphate usually contains 50%-52% of active ingredient, and is a good potassium sulfate compound fertilizer suitable for various fruit trees, which can be used as base fertilizer and top dressing. The plant ash contains various ash elements such as potassium, calcium, magnesium, sulfur, iron, silicon and the like(14cm plastic grow pots). Among them, potassium and calcium are the most, followed by phosphorus.
Potassium dihydrogen phosphate is a colorless tetragonal crystal or white crystalline powder(120mm plastic grow pots). The potassium content in plants generally accounts for 0.2%~4.1% of the dry matter weight, second only to nitrogen. Gramineous wood ash contains K2O-8.09%, P2O5-2.3%, and CaO-10.72%. Grass ash can be used as base fertilizer and top dressing(15cm plastic grow pots). Potassium can improve the stress resistance of crops, such as drought resistance, cold resistance, lodging resistance, and resistance to pests and diseases.

As shown below: If the crop lacks potassium fertilizer, it will get "chondrosis", which is easy to fall down. It is often called "quality element" by potassium bacteria. Its main effects on the quality of crop products are: it can promote the better use of nitrogen by crops(16cm plastic grow pots), increase the protein content, and promote the production of sugar and starch.
The nucleolus, seeds, fruits and tubers, roots are enlarged, and the shape and color are beautiful(plastic nursery pots manufacturers). Increase the oil content of oil crops and increase the vitamin C content of fruits. Accelerate the ripening of fruits, vegetables and other crops to align the maturity. Enhance the ability of products to resist bumps and natural rot, and extend storage and transportation(19cm plastic grow pots). Increase the strength, length and fineness of cotton and hemp crop fibers, and the purity of color, which can be used as base fertilizer, top dressing and top dressing.
(bulk buy plastic greenhouse plug plant trays) When the crop is deficient in potassium(plastic nursery pots wholesale), the old leaves and leaf margins are usually yellow, and the burnt leaves are burnt; brown spots or plaques appear on the leaves, but the central leaves, veins and proximal veins are still green. As the degree of potassium deficiency increases, the whole leaf becomes reddish brown or dry, and necrosis occurs; the root system is short and few(16.5cm plastic grow pots), easy to prematurely decay, severely decay, and easy to fall.
