微生物肥料的主要优点是可以改良土壤,不污染环境,无毒副作用,是生产“绿色食品”的理想肥料。将微生物肥料使用在种子和土壤上,可以增进土壤肥力,协助植物吸收营养,增强植物抗病和抗旱能力,节约能源,降低生产成本,减少环境污染。一、微生物肥料的分类1、固氮菌肥料可以自由生活的固氮的微生物为菌种生产出来的固氮菌肥料。按照菌种和特性可分为自生固氮菌肥料,根际联合固氮菌肥料,复合固氮菌肥料。固氮菌肥料可用于各种作
The main advantage of microbial fertilizer is that it can improve the soil, does not pollute the environment, and has no toxic and side effects. It is the ideal fertilizer for producing “green food”. The use of microbial fertilizer on seeds and soil can enhance soil fertility, assists plants to absorb nutrients, enhance plant disease resistance and drought resistance, save energy, reduce production costs and reduce environmental pollution. First, the classification of microbial fertilizer 1, Azotobacter fertilizers Free-living nitrogen-fixing microorganisms for the production of nitrogen-fixing bacteria and fertilizers. According to the strains and characteristics can be divided into autotrophic Azotobacter fertilizer, rhizosphere nitrogen-fixing fertilizer, nitrogen-fixing compound fertilizer. Azotobacter fertilizers can be used for a variety of crops
