随着我国社会主义农业的迅速发展,对磷肥的需要也曰益增多。磷肥的生产虽然不断增长,但仍不能满足要求。为此,磷纽菌肥料的生产和应用成了解决这个矛盾的有效途径之一。一般土壤中都含有大量的磷素成份,据测定,耕作层中每亩含磷量有上百斤,如果能充分利用,相当施过磷酸钙一吨以上。但是这些磷素绝大部分不能被作物直接吸收和利用。就是施用的磷肥,由于土壤的固定等其他原因,其利用率一般也不超过百分之二
With the rapid development of socialist agriculture in our country, the demand for phosphate fertilizer is also increasing. Although the production of phosphate fertilizer continues to grow, it still can not meet the requirements. To this end, Phosphorus bacteria fertilizer production and application has become an effective way to solve this contradiction. In general the soil contains a large amount of phosphorus content, according to the determination of tillage layer of phosphorus per acre have hundreds of jins, if you can take full advantage of quite over a ton of calcium phosphate. However, the vast majority of these phosphorus can not be directly absorbed and utilized by crops. Is the application of phosphate fertilizer, due to soil fixation and other reasons, its utilization is generally not more than two percent
