钾是作物营养三要素之一,钾能促进作物多种代谢作用,钾能增强作物的抗逆性。土壤中钾的形态可分为速效钾、缓效钾和难溶性钾三类,只有速效钾易被作物吸收利用,但速效钾一般只占全钾量的1～2%,需要增施钾肥,才能满足作物生长需要。近年来,随着生物肥料的研制应用,开辟了我国钾素的新肥源。生物钾肥又称硅酸盐菌剂,具有分解并转化土壤硅酸盐和磷灰石等主要矿物质中的钾,使之变成易被作物吸收的速效钾,起到钾肥的作用。生物钾肥还具
Potassium is one of the three elements of crop nutrition, potassium can promote a variety of crop metabolism, potassium can enhance the resistance of crops. The form of potassium in soils can be divided into three types: quick-acting potassium, slow-acting potassium and insoluble potassium. Only quick-acting potassium is easily absorbed by crops, but available potassium generally accounts for 1-2% of total potassium, To meet the needs of crop growth. In recent years, with the development and application of biological fertilizers, opened up new sources of potassium in China. Potassium biological fertilizer, also known as silicate bacteria agents, with the decomposition and transformation of soil silicate and apatite and other major minerals in the potassium, making it easily absorbed by crops readily available potassium, play a role of potash. Biological potassium fertilizer also with
