Compound microbial fertilizer

The invention relates to a compound microbial fertilizer. The compound microbial fertilizer is prepared from, by weight, 1-2.5% of microbial flora, 8-70% of rice bran, 10-80% of calcium superphosphate and 2-35% of potassium chloride. The microbial flora can promote effective absorption of phosphate fertilizer, and the efficiency of nitrogen fertilizer can be freely controlled; during flower bud differentiation of crops, nitrogen in leaves can be reduced to be converted into amino acid, and growth nutrients are converted into reproduction nutrients to enter fruits. In crop observation, leaf growth slows down and even stops, mesophyll is thickened due to protein synthesis, buds emerge, fruits become plump and sweet, and the fruit flavor is restored, which is an achievement of the balance of nitrogen, phosphorus and potassium in the crops. 本发明涉及种复合微生物菌肥，其各成份重量百分比如下：微生物菌1-2.5%，米糠8-70%，过磷酸钙10-80%，氯化钾2-35%。微生物菌可以促进磷肥的有效性吸收，而可以自由操作氮肥之肥效，在作物花芽分化时，可还原叶面中氮素，将氮素转化为胺基酸，由生长营养转化为生殖营养，进入果实当中。在作物观察上，叶面生长迟缓甚至停顿，因蛋白质合成而叶肉增厚，花芽
