Embodiment 1

[0025] A water-retaining and nitrogen-fixing compound microbial fertilizer prepared according to the following method:

[0026] 1) Preparation of fermentation broth: dry the wheat straw, then crush it into straw powder with a pulverizer, put it into the fermenter, then add soybean meal, bran and water at 100°C to the fermenter, stir evenly, and wait until it is reduced to 30°C At ℃, add the compound bacterial liquid, and ferment for 48 hours under the condition of stirring at 100 rpm to obtain the fermentation liquid; wherein, the mass ratio of straw powder, soybean meal, bran, water and the mixed bacterial liquid is 10:3:3:50 : 1; the composite bacteria liquid is mixed according to the volume ratio of 1:1:1:1 by Bacillus megaterium liquid, Bacillus licheniformis liquid, Trichoderma harzianum liquid and nitrogen-fixing bacteria liquid, and the concentrations of the four bacterial liquids are 5×10 7 a / ml;

[0027] 2) Preparation of compound organic raw material liquid: Add pe...

Embodiment 2

[0033] A water-retaining and nitrogen-fixing compound microbial fertilizer prepared according to the following method:

[0034]1) Preparation of fermentation broth: dry the wheat straw, then crush it into straw powder with a pulverizer, put it into the fermenter, then add soybean meal, bran and water at 100°C to the fermenter, stir evenly, and wait until it is reduced to 30°C At ℃, add the compound bacterial liquid, and ferment for 48 hours under the condition of stirring at 150 rpm to obtain the fermentation liquid; wherein, the mass ratio of straw powder, soybean meal, bran, water and the mixed bacterial liquid is 10:3:3:50 : 1; the composite bacteria liquid is composed of Bacillus megaterium liquid (ATCC15450), Bacillus licheniformis liquid (ATCC14580), Trichoderma harzianum liquid (ATCC20873) and Azotobacter rotunda liquid (ATCC4412) according to the ratio of 1:1:1:1 The volume ratio was mixed, and the concentrations of the four bacterial solutions were all 5×10 7 a / ml; ...

Embodiment 3

[0040] Fertilizer effect test of fertilizer of the present invention:

[0041] The influence of the fertilizer of the embodiment of the present invention 1 on strawberry yield and quality. The experimental variety is Fengxiang. 80kg / mu of this product was applied to the test group, and 80kg / mu of commercially available compound fertilizer (N20P10K10) was applied to the control group, both of which were conventionally cultivated. The results are shown in Table 1. Compared with commercially available compound fertilizers, the fertilizer of Example 1 of the present invention can increase the sugar content of strawberries, improve the color, and increase the yield.

Abstract

The invention belongs to the field of biological organic fertilizers, and discloses a moisture-retaining and nitrogen-fixing compound microbial fertilizer. The preparation method of the fertilizer comprises the following steps: (1) preparing fermentation broth; (2) preparing compound organic matter feed liquid; (3) preparing the compound microbial fertilizer. According to the fertilizer, agricultural waste is effectively utilized, a microbial fermentation technology is used, and the soil structure is improved, and loss of nutrition in the using process is controlled, so that the fertilizer efficiency is more durable. The compound microbial fertilizer has the effects of promoting high stable yield of crops, even and strong seedlings and the like.

Description

[0001] Technical field [0002] The present invention is a fertilizer technology field, which involves a composite microbial fertilizer and its preparation methods with water retention and nitrogen. [0003] Background technique [0004] With the continuous development of agricultural modernization, the production enthusiasm of farmers' masses is unprecedented. In order to increase the output of agricultural products, it is the main way to increase the production of chemical fertilizers in the land to increase the production of grain.It can quickly improve and meet people's life needs.But on the other hand, while investing a large amount of fertilizers for production, it ignored the adverse effects of chemical fertilizer's quality, soil board, groundwater, and ecological environment of agricultural products.As the amount of fertilizers increased sharply, and the variety was single (mostly inorganic salt fertilizer), there were fewer organic fertilizers, which caused the organic m...
