To master the correct application of potash fertilizer, attention should be paid to the following four aspects:
First, due to soil application
As the current shortage of potash resources, potassium fertilizer should be placed in the first area of ​​serious potassium deficiency. When the general soil available potassium is lower than 80mg/kg, the effect of potash fertilizer is obvious, and potassium fertilizer should be added. When the soil available potassium is 80-120mg/kg, the potassium is not applied or temporarily applied. From the soil texture, the content of available potassium in sandy soil is often low, and potassium fertilizer should be added. The content of available potassium in clay soil is often high, and it can be applied less or not. Potassium sulfate may be used in soils that are deficient in potassium and sulfur.
Second, due to crop application
Applied to potassium and legume crops, legume crops, cotton, tobacco, tobacco and other economic crops, as well as corn cereals, hybrid rice and so on.
In most rainy areas or areas with irrigation conditions and good drainage conditions, potassium chloride can be applied to most crops. For a few economic crops to improve quality, potassium chloride should not be used. The rational application of potash fertilizer is determined by the requirements of the product traits for agricultural production and its use. In addition, because different crops require different amounts of potassium and root absorption capacity of potassium can not, the response degree of crops to potash fertilizer also have differences, from the results of years of application of potash fertilizer, corn, cotton, oil crops, potash fertilizer yield increase is best, can be It reached 11.7% to 43.3%, followed by wheat and other crops.
Third, pay attention to the rotation of potassium
In winter wheat and summer maize rotations, potassium fertilizer should be given priority to corn.
Fourth, pay attention to the reasonable mix between potash fertilizers
Potassium sulfate should be used for tobacco, sugar crops and fruit trees. Potassium chloride is more suitable for fiber crops. Due to the high cost of potassium sulfate, potassium sulfate can be used in high-efficiency and economic crops; and for general field crops, except for a few chlorine-sensitive crops, cheaper potassium chloride should be used.
Greenhouse Hardwares
Greenhouse Cross Connectors are used to tie together two piece of pipe in the greenhouse structure or other application.
