Abstract

The invention discloses a small molecule alginic acid microbial fertilizer, which comprises, by weight, 7-15 parts of a biological enzymolysis small molecule alginic acid solution, 15-25 parts of a compound microbial agent, 5-15 parts of humic acid, 5-10 parts of urea, 1-5 parts of boric acid, 0.2-0.5 part of EDTA-Cu, 0.3-0.6 part of EDTA-Fe, 1-3 parts of EDTA-Zn, 0.1-0.2 part of EDTA-Mn, and 0.06-0.1 part of ammonium heptamolybdate. According to the present invention, the small molecule alginic acid microbial fertilizer can avoid the destruction caused by strong alkalis, high temperature andhigh pressure, avoid the decomposition of active substances such as alginic acid, plant growth promoting factors and the like under mild process conditions, and maintain the effective active components in seaweed at a maximum; after alginic acid is released, the alginic acid is further subjected to enzymolysis to form the low molecular weight alginic acid so as to be easily absorbed and used by plants; and the liquid rich in the small molecule alginic acid is prepared, and is compounded with the special forma, and the agricultural microbial bacteria with specific functions are added, such thatthe nutrient requirements and the stress resistance of crops can be completely met.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a micromolecular alginic acid microbial fertilizer. Background technique [0002] my country is a large agricultural country, and the demand for chemical fertilizers in food production is very large. my country's traditional agriculture relies on the input of chemical fertilizers for a long time, which makes the soil compacted and acidified, and the utilization rate is reduced, resulting in waste of resources and environmental pollution. In addition to the three major crops dominated by rice, wheat and corn, the planting scale of vegetables and fruits has been expanding year by year. Compared with traditional food crops, the planting requirements of vegetables and fruits are higher, and the use of fertilizers is more refined. In addition to the nitrogen, phosphorus and potassium required for growth, there are additional functions. This requires the development of new types of plant nut...
