Embodiment 1

[0018] Example 1: Take 100 parts of mixed silkworm excrement or waste silkworm excrement after extracting chlorophyll, add 0.2 parts of microbial bacteria, mix and stir evenly, adjust the moisture content to 55%, and the C / N ratio to about 28, and carry out accumulation fermentation. During the fermentation process, the compost should be turned over and ventilated. After the temperature rises to 60°C, the compost should be turned over every 24 hours. When the temperature of the pile has dropped to ambient temperature, the fermentation is almost complete and takes 12-16 days in total. Then dry, granulate, and sieve to obtain granular organic fertilizer for protected cultivation, and then pack the finished product.

Embodiment 2

[0019] Embodiment 2: in facility grape, use the organic fertilizer 300 kilograms / mu that the present invention makes, make basal manure and use, the grape quality that can compare conventional application vegetable cake treatment obviously improves, single fruit weight significantly increases, but fertilizer cost is only and the latter's 53%, and play a role in improving the soil.

Embodiment 3

[0020] Embodiment 3: use the organic fertilizer prepared by the present invention for greenhouse eggplant, apply 500 kilograms of silkworm excrement organic fertilizer per mu, apply before transplanting, can obviously improve eggplant yield and quality, fresh eggplant increases production by 15-20%, taste Significant improvement.

Abstract

The invention discloses a method for producing a specialized organic fertilizer for protected cultivation by silkworm excrement fermentation, comprising the following steps of: inoculating active microorganisms to silkworm excrement, uniformly stirring, fermenting at high temperature, drying, granulating and sieving. According to the invention, silkworm excrement can be fully utilized to save resources and solve the pollution problem of waste silkworm excrement. The pH value of the silkworm excrement specialized organic fertilizer prepared in the invention ranges from 7.0 to 8.0, thus effectively solving the soil acidification problem frequently caused in protected cultivation. The organic fertilizer maintains original growth activating substances of silkworm excrement, contains a lot of beneficial microorganisms and more than 50% of organic matters, can be used to increase crop yield, improve crop quality and fertilize and improve soil, and is a good fertilizer for the production of nuisance free agricultural products.

Description

technical field [0001] The invention relates to a method for using silkworm excrement to ferment and produce special organic fertilizer for facility cultivation. Background technique [0002] Sericulture has a long history in my country and has been very developed. In recent years, with the deepening of the national strategy of "moving mulberry from east to west", the silkworm industry has developed rapidly, but the silkworm excrement left after sericulture has not been fully utilized for a long time. For a long time, silkworm excrement is generally directly used as farmland fertilizer or discarded. Because fresh silkworm excrement contains certain pathogenic bacteria, if it is used as fertilizer or discarded, it will cause serious pollution to the silkworm production environment, and even lead to outbreaks of silkworm diseases. Silkworm excrement has become one of the main non-point source pollutants in silkworm areas. Therefore, solving the problem of silkworm excrement ...
