Kind of Microbe Fertilizer and Request for Utilization
Microbe fertilizer means that the specific product containing live microbe is used in agricultural production to obtain particular fertilizer supply. Microbe can be summarized into three kinds: one is increasing the supply of plants’ nutrients through microbe’s vital movement so as to improve plants’ nutrient condition, thus increasing agricultural crops’ yield and quality. Microbes rival the harmful microbes in the soil, and can also resist and prevent disease, and even wipe out insects. Some representative products include nodule bacteria, nitrogen-fixing bacteria, phosphate solubilizing bacteria, silicate (potassium bacteria). Most of them can revitalize soil and the dosage amount is about 2 kg. Another kind is metabolic substance of microbes. The complex collected from industrial cultivation, such as amino acid, is made into mineral trace element liquid or solid product by cooperating with mineral trace element, so as to stimulate corps’ growth or resist diseases and insect pests. The dosage amount is around 100 grams. The third way is with the help of microbes decomposing organic matter, for example, enzyme microorganism can accelerate the rot of farmyard manure or straw, so as to increase the soil humus.
