Biopotash fertilizer is a new type of stimulation agent, namely silicate bacteria. It has two types of formulations: First, peat formulations, the appearance of a black powdery solid, loose moisture, water content of about 30%; the other is a liquid formulation, appearance milky, cloudy, slightly sour. According to the data, 1 kg of bio-potash fertilizer applied per 667 square meters is equivalent to 15 kg of potassium sulfate or 15 kg of potassium chloride or 30 kg of superphosphate per 667 square meters, and the fertility and soil fertility have no pollution to the soil. Production practice 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, alkaline nitrogen and available phosphorus. Too thin sandy lands and soils with poor water and fertility retention are unsuitable for application, and potassium-deficient soils with a soil available potassium content of less than 100 mg/kg. The best effect is to increase yield. Second, pay attention to water conditions. In the irrigated areas where irrigated soils are used, the application of bio-potassium fertilizers has a significant yield increase effect. In dry lands without irrigation conditions, the living organisms of bio-potassium fertilizers cannot grow normally, and the functions of transforming and decomposing soil potassium and phosphorus cannot be normalized. obvious. Experiments have shown that the use of bio-potassium fertilizer in high-water-fertilizer, high-nitrogen-phosphorus fields can balance the supply of nitrogen, phosphorus, and potassium and increase the yield of agricultural crops. 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 fertilizers, they should not be exposed to sunlight. The seed dressing should be carried out indoors or in a shed. The seeds of the inoculant should be dried in the shade and not dried. The day of seed dressing is broadcasted on the day of application. Fifth, biopotash fertilizers can be used in combination with urea, ammonium nitrate, ammonium sulfate, potassium sulfate, potassium chloride and other fertilizers. However, it should not be stored unless it is mixed and used. It must not be mixed with alkaline substances such as grass ash to avoid killing bacterial cells and affecting fertilizer efficiency. Sixth, pay attention to early application. Since bio-potassium fertilizers are applied to the soil, it takes a process for bacteria to decompose and release potassium and phosphorus from the settlement and propagation of soil minerals. In order to ensure that there is sufficient time to complete the process and that potassium and phosphorus nutrients can be provided from the seedling stage of the crop, early application must be observed. 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, it is necessary to pay attention to the application of uniform, so that it is beneficial to the full play of the role of microbial agents.
