AI Technical Summary

Problems solved by technology

But its shortcoming is: using above-mentioned three types of microbial fertilizers alone can only solve one aspect of the nutrition needed by plants, and the cost is high, and the consumption is large, generally 5~60 kg / mu (666.67m 2 ); at the same time, using the three in combination will cause insufficient or wasteful fertilization because it is difficult to achieve an appropriate ratio
Existing microbial fertilizers contain less viable bacteria (generally 100-500 million / g) is another shortcoming

Embodiment 1

[0010] 1. Strains

[0011] 1. Azotobacter beijerinkii

[0012] A species of nitrogen-fixing bacteria (Azotobacter). Long, 2 microns wide, usually forming a chain. Gram-negative, non-spore-forming. Grows slimy on carbohydrate-containing media. Has nitrogen fixation.

[0013] 2. Pseudomonas fluorescens

[0014] A species of Pseudomonas. Cells are straight or curved, non-spore-forming, Gram-negative, aerobic. Produces fluorescent pigments. There is only one polar flagella. It has the function of decomposing organic phosphorus and inorganic phosphorus into available phosphorus.

[0015] 3. Bacillus circulans

[0016] A species of Bacillus. Sports, anaerobic growth is good. Hydrolyzes starch, does not produce lecithinase, VP negative. It can decompose insoluble organic potassium and inorganic potassium in the soil, and convert them into available potassium that can be directly absorbed by crops.

[0017] 4. Endomyces decipiens

[0018] A species of Endospora. Gamete...

Abstract

A composite microbe fertilizer and its production are disclosed. The fertilizer consists of Batelli's azotogen, fluorescent pseudomonads, anular spore rod and proximal inner enzyme in proportion of (15-24): (19-28): (23-33): (20-36). The process is carried out by culturing for four composite microbe pools, fermenting, and combining fermented products into composite microbe fertilizer proportionally. It's various and cheap, has better soil quality and structure and more yield.

Description

technical field [0001] The invention relates to a fertilizer in agricultural technology, which is a biological fertilizer, in particular a novel 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 fertilizer, which is mainly composed of bacteria and fungi with nitrogen-fixing effect; another example: phosphorus bacteria, whose function is to decompose organic phosphorus or inorganic phosphorus in the soil, making it easy to be absorbed by plants; another example : Potassium bacteria, whose function is to decompose potassium compounds in the soil and make them into available potassium that can be absorbed and utilized by plants. These fertilizers can play their respective roles when used alone, and partially meet the needs of plants for the three elements of nitrogen, phosphorus, and potassium. They do not produce the soil ...
