AI Technical Summary

Problems solved by technology

At present, a large number of fruit and vegetable residues are randomly discarded in the fields, burned or left to rot naturally, causing the breeding and spread of diseases and insect pests, emitting odor and polluting the environment
In particular, the treatment of solanaceous straws is more difficult: first, because solanaceous straws or vines carry many pathogenic bacteria, it is not easy to return them directly to the field for utilization; second, the late-growing solanaceous straws have a high degree of lignification, and traditional composting is difficult to decompose. Solution, the temperature of compost rises slowly, resulting in poor removal of pathogenic bacteria, and it is easy to cause secondary pollution after improper handling

Embodiment 1

[0020] (1) Dry the tomato vines until the moisture content is about 30%, and use a pulverizer to grind the tomato vines to a length of about 2 cm.

[0021] (2) Tomato vines and duck manure are mixed at a weight ratio of 7:3 to prepare a mixed material. Add 4% magnesium phosphate and 0.1% glucose according to the weight of the mixed material, and then adjust the water content to 60% to 70% with water.

[0022] (3) Carry out the stacking system of stacking, the bottom of the stack is 1.5m, the height is 1m, and the film is covered. Turn over once every 10 days, and turn over 3 times in total.

Embodiment 2

[0024] (1) Dry the tomato vines until the moisture content is about 30%, and use a pulverizer to grind the tomato vines to a length of about 2 cm.

[0025] (2) Mix the pulverized tomato vines with 1% quicklime, and stack them in a circular pile with a height of 1.5m.

[0026] (3) Sprinkle water evenly according to 5% of tomato weight, then cover with thicker plastic film, compact and seal with soil around, and pre-stack for 5 days.

[0027] (4) Pre-composted tomato vines and duck manure were mixed at a weight ratio of 7:3 to prepare a mixed material. Add 4% magnesium phosphate, 0.1% glucose, and 1% wood vinegar according to the weight of the mixed material, and then adjust the water content to about 65% with water.

[0028] (5) Carry out stacking of stacked materials, between 1.5m at the bottom of the stack, with a height of 1m, and covered with film. Turn over once every 10 days, and turn over 3 times in total.

Abstract

The invention relates to a composting method, in particular to a safe composting and on-site returning method for solanaceous fruit straws. The method comprises the following steps: carrying out two-stage composting on solanaceous fruit straws, wherein in the first stage, the crushed straws and quick lime are primarily stacked; in the second stage, the mixed material is composted again, and the composted and decomposed material is directly returned to the field on the spot. According to the method, two-stage composting is adopted, the first stage is primary composting of waste and quick lime, and the main target is sterilization; in the second stage, the mixed materials are composted, and sterilization and decomposition are carried out again. And the composted and decomposed material is returned to the field according to about 1000-2000kg / mu, so that the safe field returning of the solanaceous fruit straws is realized, and the fertility of the vegetable field is improved.

Description

technical field [0001] The invention relates to a composting method, in particular to a method for safely composting and returning field solanaceous straws. Background technique [0002] In recent years, the rapid development of my country's facility agriculture has played a very important role in effectively ensuring the seasonal and balanced supply of vegetables in my country. In 2013, Fujian vigorously supported the development of vegetable planting facilities. By 2018, the area of ​​various types of facility vegetables in our province reached more than 1.3 million mu, especially solanaceous vegetables, which are the main varieties grown in winter greenhouses in Fujian Province. [0003] According to the survey, a large number of residual plants, vines, straws, fruit shells and other residues are produced in the process of fruit and vegetable production, which is the fourth largest crop straw, accounting for about 10% of the total output of crop straw. At present, a larg...
