Biopotash fertilizer is a new type of stimulation agent, namely silicate bacteria. It has two dosage forms, one is a peat type, black powdery solid appearance, loose moisture, about 30% water content. The other is a liquid dosage form that has a milky appearance, is cloudy, and has a slightly sour taste. According to the data, 1 kg of bio-potash fertilizer applied per acre is equivalent to the application of 15 kg of potassium sulfate or 15 kg of potassium chloride or 30 kg of superphosphate, and the fertility and fertility of the soil do not pollute the soil. The production practice shows that applying biopotassium fertilizers must be based on certain key environmental techniques to achieve good yield increase. First, pay attention to soil conditions. Biopotash 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 properties are not suitable for application. The effect of increasing potassium production on potassium-deficient soils with available potassium content less than 100 ppm the best. 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, biological potash can not be stored and used in sunlight exposure environment. Seed dressing should be carried out indoors or in the shed. Seeds with fungicide should be dried in the shade and not dried. . Fifth, biopotash fertilizer can be used for top dressing in combination with urea, ammonium nitrate, ammonium sulfate, potassium sulfate, potassium chloride and other chemical 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. In order not to kill the bacteria cells, affect the fertilizer effect. Sixth, pay attention to early application. Since biological potassium fertilizers are applied to soil, bacteria need a process from settlement and propagation to the decomposition of potassium and phosphorus from 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, we must pay attention to Shihyun, so that it will be conducive to the full play of bacterial crops. 40m Laser Distance Meter is a functional and advanced measuring tools, no need climbing up and down, which is the engineers' best friends.
