Biopotash fertilizer is a new type of stimulation agent, namely silicate bacteria. The production practice in several areas in recent years shows that applying biopotassium fertilizer must pay attention to the key application techniques under certain environmental conditions in order to exert a good yield increase effect.
First, pay attention to soil conditions. Biopotassium fertilizers have good application effects on loamy soils rich in organic matter, alkali-hydrolyzed nitrogen, and available phosphorus. Too thin sandy lands and soils with poor water and fertility retention are not suitable for application. Potassium-deficient soils with a soil available potassium content of less than 100 ppm are used to increase production. best effect.
Second, pay attention to water conditions. For irrigated land with irrigation conditions, the application of bio-potassium fertilizer has obvious effect on yield increase.
Third, priority should be given to the use of crops that reproduce on the upper and lower crops.
Fourth, when storing and using bio-potassium fertilizer, it cannot be exposed to sunlight. The seed dressing should be carried out indoors or in a shed.
Fifth, biopotash fertilizers can be used in combination with fertilizers such as urea, nitrate, ammonium sulfate, potassium sulfate, and potassium chloride. However, it should not be stored unless it is mixed and used. It must not be mixed with alkaline substances such as ash.
Sixth, pay attention to early application. According to the experiment, the application effects of base application, seed dressing, root picking and seedling transplanting were better before soil preparation. If it is topdressing, it is better to recover early in the seedling period; on the contrary, the later the application, the worse the effect.
Seventh, to be near, that is, to apply biological potassium fertilizer around the roots, the closer you can, the better.
Eighth, we must pay attention to Shihyun, so that it will be conducive to the full play of bacterial crops.
