复合生物肥是我们近年来在根瘤菌肥研究基础上开发研制的又一新型接种剂，该肥富含多种有益微生物，菌种是经过严格筛选，以固氮菌为主，并具有解磷、解钾功能。同时对优化组合的菌种进行其生理生化特性鉴定，确定它们的有效性指标为：硅酸盐细菌在含钾长石粉的无氮培养基上接种培养１０ｄ，可使水溶性钾含量增加１３１．５１％；磷细菌在含有卵磷脂的琼脂平板上，能观察到明显的溶磷圈；固氮菌的固氮酶活性为２．０５μｍｏｌＣ２Ｈ４／（株·ｈ）。并对菌种的发酵条件进行了探索，摸索出混合发酵液配方。对菌肥的耐贮性、安全无毒性进行了有效测定。
Compound biological fertilizer is a new type of inoculant that we developed and developed based on rhizobium fertilizer research in recent years. The fertilizer is rich in many beneficial microorganisms. The strain is strictly selected to mainly nitrogen-fixing bacteria, Potassium function. Meanwhile, the physiological and biochemical characteristics of the optimized strains were identified, and the indicators of their effectiveness were determined as follows: Silicate bacteria inoculated on nitrogen-free medium containing potassium feldspar powder for 10 days could increase the content of water-soluble potassium 131. 51%. Phosphobacteria showed obvious phosphate solubilization on agar plate containing lecithin. Azotobacter had nitrogenase activity of 2.05μmolC2H4 / (h · h). The fermentation conditions of the strains were explored, to explore the mixed fermentation broth formula. Storage of bacterial fertilizer, safe and non-toxic were effectively measured.
