几种农作物矿物增效复合专用肥的应用研究

Development of Minerals-effecting Compound-Special Fertilizers

由沸石、膨润土和麦饭石等几种物化性能优越的非金属矿物按一定比例配合并粉碎成一定的粒度，再根据不同农作物生长所需的养分特点，与氮、磷或氮、磷、钾肥和微素（ 肥） 混合制成矿物增效复合专用肥。这种肥料既具有普通复合专用肥的特点，还具有保水。

Some nonmetallic minerals with superior physical-chemical properties, such as zeolite, montmorillonite, maifanite, etc., are mixed together in a certain proportion, crashed in a certain size and manufactured as powders. On basis of nutrient characteristics of different crops and trees, the powders are mixed with compound fertilizer containing N and P or N, P and K and microelements fertilizers to manufacture minerals-effecting compound-special fertilizers. They not only possess the characteristics of common compound-special fertilizers, but also possess their special function of keeping water and nutrients of fertilizer in soil and improving the soil.
