Problems solved by technology

Although some compound microbial agents have appeared on the market, their functions are single, or their use methods are limited, and the effect of increasing crop production after use is still unsatisfactory. Composite microbial agent or fertilizer with comprehensive functions and good yield-increasing effect
[0005] Due to the long-term lack of investment in microbial fertilizer research in China, my country's microbial fertilizer industry still has problems such as low overall level, insufficient technological innovation, and unstable product quality and application effects.

[0120] (2) Secondary seed cultivation: Put the first-grade seeds into 500 ml second-grade seed shake flasks according to the inoculation amount of 10%, and the cultivation conditions are the same as the first-grade seeds;

[0121] (3) Tertia...

Embodiment 3

[0140] A micro-ecological compound fertilizer, the number of parts by weight is: 4 parts of colloid bacillus bacteria agent, 5 parts of Bacillus megaterium phosphorus solubilizing agent, 14 parts of bacillus subtilis culture, 13 parts of aspergillus niger culture, plant lactobacillus agent 3 copies.

[0141] The invention discloses a method for producing micro-ecological compound fertilizer. The micro-ecological compound fertilizer is obtained by combining the bacillus colloid bacteria agent, Bacillus megaterium phosphate solubilizer, Bacillus subtilis, culture of Aspergillus niger and plant lactobacillus in proportion.

[0142] Preparation of Bacillus subtilis agent culture: transfer and cultivate Bacillus subtilis from the slope, transfer the seed liquid after step-by-step expansion into the fermentation tank, and after the fermentation is completed, the fermented liquid is filtered and dried to obtain the Bacillus subtilis agent. Cultures.

[0143] Preparation of Lactobaci...

Abstract

The invention discloses a microecological compound fertilizer belonging to the technical field of agricultural fertilizers. The microecological compound fertilizer comprises the following components in parts by weight: 3-6 parts of bacillus mucilaginosus preparation, 2-6 parts of phosphorus-dissolving bacillus megaterium preparation, 10-15 parts of bacillus subtilis cultures, 8-15 parts of aspergillus niger cultures and 1-4 parts of lactobacillus plantarum preparation. The fertilizer disclosed by the invention can be used for improving the micro-ecological environment of soil and providing beneficial conditions for the growth of crops. The bacillus mucilaginosus in the composite bacteria can secrete growth promotion substances such as auxin substances, gibberellin substances and the like so as to have the effect of promoting root and seedling growth; the silicon element in soil is decomposed and used by plants, so that the wax layer of a plant is thickened, and the water retaining property of the plant is improved; the aspergillus niger used in the microecological compound fertilizer has the characteristic of generating high-activity cellulose which is beneficial to the decomposition of soil organic matters, the formation of humic substances and the release of carbon nutrients.

Description

technical field [0001] The invention relates to a biological fertilizer, which belongs to the technical field of agricultural fertilizers, in particular to a micro-ecological compound fertilizer. Background technique [0002] Microbial fertilizer is a microbial living product that uses microbial life activities and its products to cause crops to obtain specific fertilizer effects. It can improve soil fertility, improve fertilizer utilization, inhibit crops from absorbing harmful substances such as heavy metals and pesticides, and purify and restore soil. It plays an irreplaceable role in promoting the utilization of crop stalks and urban waste, and improving the quality of agricultural products. The efficacy of microbial fertilizers is mainly achieved through the synergistic effect on traditional chemical fertilizers and organic fertilizers, the improvement and activation of soil, and the physiological effects of microorganisms. [0003] Therefore, microbial fertilizers hav...
