Problems solved by technology

Due to the high lignification of mulberry trees, the mulberry branches decompose slowly under natural conditions, and the mulberry branches randomly placed in the mulberry garden seriously hinder the follow-up mulberry leaf collection and reduce the production efficiency of sericulture.

Embodiment 1

[0023] A method for quickly decomposing mulberry branches in situ, the steps are:

[0024] a. Take 10 kg of mulberry branches in the mulberry garden, let them keep the field humidity and crush them (moisture content 43.3%, diameter ≤ 1cm).

[0025] b. Take 4 kg (moisture content 28%) of the surface layer (0-15 cm) of mulberry garden soil (moisture content 28%) that has been continuously planted with mulberry trees for more than 5 years and has returned mulberry branches to the field in the past two years, and let it maintain natural humidity.

[0026] c. Take 10 kg of sawdust (with a moisture content of 12.6% and a diameter of 1 to 3 mm) from a local wood processing factory; according to mulberry branch debris: sawdust: mulberry garden soil: urea: 10 kg: 10 kg: 4 kg: 1 kg Mix the proportions and put them into a clean vat (or similar container), with a total of 25 kg of the mixture.

[0027] d. Add 20.0 kg of water to the container until the water content of the mixture is ab...

Abstract

The invention relates to a mulberry twig in-situ rapid composting method, which comprises the steps of: a. collecting mulberry twig with a moisture content of 38-47% and conducting crushing to a diameter of less than or equal to 1cm; b. taking mulberry field soil with mulberry twig returning to field and a moisture content of 25-35%; c. mixing mulberry twig chip and sawdust, mulberry field soil and urea in a ratio of 10-30:10-30:3-5:1; d. adjusting the moisture content, then placing the mixture indoors, keeping the room temperature at 20-30DEG C, conducting turnover once every 2-3 days, 3 times, and carrying out enrichment culture for 7-8d so as to obtain a preparation containing a lot of mulberry field aboriginal decomposed mulberry twig microorganisms; e. after mulberry twig trimming, spraying urea on the mulberry field soil and mulberry twig surfaces to adjust the carbon nitrogen ratio of the composting environment; and f. spraying a microbial preparation. The mulberry twig composting method provided by the invention has excellent effect and is simple and easy to operate, thus being suitable for popularization and application in extensive mulberry large-scale planting areas.

Description

technical field [0001] The invention belongs to the technical field of organic matter decomposition, and in particular relates to a method for in-situ rapid decomposing of mulberry branches, which is mainly applied to mulberry gardens in southern karst areas. Background technique [0002] The output of silkworm cocoons in southern China accounts for 90% of the total output of silkworm cocoons in the country. Sericulture is an emerging agricultural advantageous industry in the karst poverty-stricken areas of southern China, and has made important contributions to the promotion of agricultural efficiency, farmers' income and regional economic development in the area. Taking Guangxi as an example, the area of ​​mulberry fields in 2014 was about 2.8 million mu, and its silkworm cocoon production, silkworm seed production and mulberry field area all ranked first in the country. In the production process of mulberry leaves, in order to increase the yield of mulberry leaves and pr...
