Compound microbial fertilizer and production method thereof

Abstract

The invention discloses a compound microbial fertilizer and a production method thereof, particularly relates to a compound microbial fertilizer capable of meeting comprehensive requirements of a plant on nitrogen, phosphorus and potassium and a production method thereof, and aims at solving the technical problem that the existing microbial fertilizer just can solve one aspect of the nutrition required by the plant when being independently used, resulting in high cost and large dosage, and proper ratio cannot be easily controlled when the microbial fertilizer is used cooperatively, resulting in shortage or waste of the fertilizing amount. The compound microbial fertilizer is prepared from fermented matters of azotobacteria, phosphobacteria and potassium-bacteria in a mixing manner. After adopting the technical scheme, the comprehensive requirements of the plant on nitrogen, phosphorus and potassium can be met; development of agricultural production is facilitated. The compound microbial fertilizer can be utilized instead of over 60% of nitrogen, phosphorus and potassium fertilizers, so that the planting cost can be reduced; the yield is greatly improved; the quality and the flavors of grain and vegetables also can be improved.

Description

technical field [0001] The invention relates to the field of bioengineering, in particular to a compound microbial fertilizer and a production method thereof. Background technique [0002] Most of the existing microbial fertilizers are single microbial fertilizers, such as nitrogen-fixing bacterial fertilizers, which are mainly composed of nitrogen-fixing bacteria and fungi, and phosphorus bacteria, whose function is to decompose organic phosphorus in the soil and make it easily Phosphorus absorbed by plants, such as potassium bacteria, its function is to decompose potassium compounds in the soil, making it easy to be absorbed and utilized by plants. These fertilizers can play their own roles when used alone, and partially meet the needs of plants. Nitrogen, phosphorus, potassium three elements needs, they will not produce soil compaction caused by long-term use of chemical fertilizers, but its disadvantage is: the use of the above three types of microbial fertilizers alone ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the existing microbial fertilizer can only solve one aspect of the nutrition required by plants when used alone, the cost is high, the dosage is large, and when used in combination, it is difficult to achieve an appropriate ratio, resulting in insufficient or wasteful fertilization. , providing a compound microbial fertilizer capable of meeting the comprehensive needs of plants for nitrogen, phosphorus, and potassium, and a production method thereof
