Description

复合微生物菌肥生产方法Production method of compound microbial fertilizer

(一)技术领域(1) Technical field

本发明属于生物菌肥生产技术领域。The invention belongs to the technical field of biological bacterial fertilizer production.

(二)背景技术(2) Background technology

土壤微生物是土壤重要物质组成之一,在土壤养分转化过程中有重要作用。土壤是微生物的大本营,其生物多样性是其功能多样性的前提条件,而菌种的优化组合是其正面功能充分发挥的重要保证。我国早期研制的微生物肥料多数只含一种微生物。其功能单一(固氮菌只固氮,解钾菌只解钾……),使用条件严格,使用后效果有时不明显。当前国际上流行多菌种复合或联合的微生物肥料,其功能全面,效果明显,应用条件相对比较粗放,深受农民欢迎。但国外对相关技术实行封锁,国内市场上为数不多的产品都是进口的。研制出功能强大,效果明显,农民欢迎的微生物肥料是生产优质无公害农业产品的关键之一。复合生物菌肥的生产一般采用先纯培养,后组合的工艺,生产成本较高,而且常温保存期短。研究筛选出对作物生长发育和土壤生态环境友好、功能互补、且有互惠效应、能互利共栖的一组菌种,并能采用混合培养工艺生产,将对我国的微生物肥料生产有重大意义。Soil microorganisms are one of the important components of soil and play an important role in the transformation of soil nutrients. Soil is the base camp of microorganisms, and its biodiversity is the prerequisite for its functional diversity, while the optimal combination of strains is an important guarantee for its full positive function. Most of the microbial fertilizers developed in my country in the early stage contain only one kind of microorganism. Its function is single (nitrogen-fixing bacteria only fix nitrogen, potassium-decomposing bacteria only decompose potassium...), the use conditions are strict, and the effect after use is sometimes not obvious. At present, multi-strain compound or combined microbial fertilizers are popular in the world. They have comprehensive functions, obvious effects, and relatively extensive application conditions, and are very popular among farmers. However, related technologies are blocked abroad, and the few products on the domestic market are all imported. Developing a microbial fertilizer with powerful functions and obvious effects, which is welcomed by farmers is one of the keys to produce high-quality pollution-free agricultural products. The production of compound biological bacterial fertilizer generally adopts the process of pure culture first and then combination, which has high production cost and short storage period at room temperature. The research screens out a group of strains that are friendly to crop growth and soil ecological environment, have complementary functions, have mutual benefit effects, and can live in mutual benefit, and can be produced by mixed culture technology, which will be of great significance to the production of microbial fertilizers in my country.
