A Multifunctional Endophytic Bacillus Fertilizer Improves the Quality of Off-season Fresh Maize
An endogenous and multifunctional bacillus fertilizer has been developed, to study its fertilization efficiency, a simple comparative experiment was conducted with off-season fresh maize growing in the sloping land of red-brown-purple soil. Compared with the control of applying 76.048 kg organic and inorganic compound fertilizer in 210 m2 soil (the normal fertilizer level), after applying 2.94 kg bacillus fertilizer in the 210 m2 soil, the quality of fresh maize was improved obviously. The water-soluble amino acids, water-soluble reducing sugar and vitamin C increased by 40%, 198% and 30%, respectively. At the same time, the crude fiber and starch content decreased by 0.15% and 10.68%, respectively. This bacterial fertilizer is valuable for further research on soil fertility.

我国土壤微生物学的奠基人、中国科学院院士、华中农业大学教授陈华癸先生曾对微生物肥料做过准确的定义.他提出,微生物肥料是一类"含有活微生物的特定制品,应用于植物生产取得特定的肥料效应,在这种效应的产生中,制品中活微生物的生命活动起关键作用."同时指出其含义包括两个不同的范畴.
