In the fall, another peak of fertilizer use has been reached. However, many farmers' friends do not pay attention to the application of potash. For example, many farmers generally plant winter wheat in the fall season, using only urea and diamine. The application of potash fertilizer is very small, and even many people do not use it at all. As one of the three major elements, the importance of potash can not be ignored.
What is the use of potash?
The first is to improve stress resistance. Potassium participates in many physiological activities during the growth of plants. It can promote the metabolism of carbohydrates and nitrogen, control and regulate the activity of various mineral nutrient elements, activate the activities of various enzymes, control the transport of nutrients and water, and maintain the cell's Internal pressure prevents the plants from wilting.
The second is to improve quality. As the application of potash fertilizer can improve the resistance of crops, it plays a very important role in ensuring high yield and stable production of crops. For example, corn, through the application of potash fertilizer, can improve the quality of corn stalks and prevent lodging.
The third is to increase production. Due to the high content of potassium in the original soil in some areas, many farmers' friends have not realized the important effect of potassium on production.
Do not apply potassium fertilizer
The application of potash has not attracted everyone's attention, and it has a great relationship with the content of potash in soil. The potassium supply capacity of soils in China is very different in different regions, generally it is low in the south, high in the north, and low in the east. However, due to the long-term lack of attention paid to the application of potash, soil potassium levels in many areas are decreasing. So, do you want to use potassium fertilizer?
Look at soil. The content of potassium in soils in China is slowly decreasing. In addition, appropriate potassium fertilizer should be applied to the northern soil.
Second, look at the crop. Since potassium plays an important role in increasing crop protein and sugar content, general economic crops promote the use of potash fertilizers, especially legumes, potato crops, cotton, hemp, tobacco, and fruit trees.
Third, look at the external nutrient input. In recent years, straw has been promoted to return to the field. This is because straw has a high potassium content and is easily released. It can supply a large amount of potassium to the soil.
Potash "three brothers", how to choose
There are many kinds of potash fertilizers. Mainstream varieties on the market include potassium sulfate, potassium chloride and potassium dihydrogen phosphate.
Potassium sulphate is more expensive than potassium chloride because it is not easy to agglomerate, has better physical properties, is easier to apply, and has higher production costs. Therefore, potassium sulfate is generally applied to crops with higher economic value.
The potassium chloride, due to its chlorine content, should be avoided when applied to avoid chlorine crops. Such as sugar beet, sugar cane, potatoes, grapes, watermelon, tea, tobacco, citrus and other chlorine crops, it is generally not suitable to use potassium chloride.
Potassium dihydrogen phosphate contains both phosphorus and potassium elements, free from impurities and residues, and nutrients can all be absorbed by crops. It plays an important role in increasing crop yields and income and improving resistance.
It is necessary to remind farmers that the price of potash itself is higher than that of urea and phosphate fertilizer. Therefore, at the time of purchase, it must not use small counterfeits and buy counterfeit products.
