Bio-potassium fertilizer is a new type of stimulation agent, namely silicate fungicide. The production practice in some areas over the past few years has shown that the application of biological potassium fertilizer must pay attention to the control of key application techniques under certain environmental conditions, and the ability to exert a good yield increase effect. The main role of potash is to improve the character of agricultural products and crop resistance. There are fewer varieties of potash, and potassium chloride, potassium sulfate, potassium magnesium fertilizer and biological potassium fertilizer are commonly used.
Pay attention to the soil conditions. The application of biological potassium fertilizer on organic matter, alkaline nitrogen and available phosphorus in rich loamy land is good. Too poor sandy land and soil with poor water retention and fertilizer retention capacity should not be applied. The available potassium content in soil is less than 100 g/m3. Potassium soil application has the best effect on increasing yield. Pay attention to the water conservancy conditions. In irrigated land with irrigation conditions, the effect of applying bio-potassium fertilizer to increase yield is obvious.
The biological potassium fertilizer is used for top dressing and can be mixed with urea, ammonium sulfate, potassium sulfate, potassium chloride and the like. However, it should be mixed and used, it should not be stored, and must not be mixed with alkaline substances such as grass ash. It should be applied preferentially to the upper and lower sorghum, and to the potassium crop. When storing and applying bio-potassium fertilizer, it should not be exposed to sunlight. Seed dressing should be carried out indoors or in a shed.
Biological potassium fertilizer should pay attention to the application of the uniformity, so as to facilitate the full play of the microbial crops, pay attention to early application. According to the experiment, the application effect is better when the foundation is applied, seed dressing, rooting and transplanting. If it is top dressing, it should be chased early in the seedling stage; on the contrary, the later the application, the worse the effect. To apply near, it is necessary to apply the biological potassium fertilizer around the roots, the closer the better.
