Method for treating rotten vegetable leaves and fermenting biofertilizer by utilizing biotechnology

Abstract

The invention discloses a method for treating rotten vegetable leaves and fermenting a biofertilizer by utilizing a biotechnology. The method comprises steps as follows: the rotten vegetable leaves are poured into a treatment tank, a compound decomposer is scattered every time the rotten vegetable leaves are stacked to be 15-25 cm thick, the rotten vegetable leaves and the compound decomposer are repeatedly added to reach the two-thirds position of the height of the treatment tank, water is added until the treatment tank is full, and the treatment tank is covered with waterproof cloth; the rotten vegetable leaves are decomposed for 7-10 days through the compound decomposer, livestock manure, decomposed coal, ammonium sulfate and a compound microbial agent are added to the treatment tank and stirred uniformly for retting, the mixture is stirred once every three days, and retting ends after the mixture is biologically fermented and composted for 15-20 days; after fermentation ends, the mixture is uniformly stirred, and a solid and liquid mixture in the treatment tank is pumped out by a feces suction truck and taken as a biofertilizer to be applied. The raw materials are easy to obtain, the rotten vegetable leaves can be treated on the spot or in the vicinity in a large-scale and harmless manner, a process is simple, energy consumption is not required, no three wastes are generated, the ecological environment is protected, the waste is turned into valuable, and the prepared biofertilizer can be directly returned to the farmland.

Description

technical field [0001] The invention belongs to the technical field of tail vegetables processing, and in particular relates to a method for treating tail vegetables and fermenting biological fertilizers by using biological technology. Background technique [0002] Mature fresh vegetables will remove some inedible parts when harvesting, such as vegetable roots, vegetable sides, and incomplete outer leaves, which will also cause damage to some vegetables during transportation. nice leaves. Before putting them on the shelves, some simple treatment will be carried out. In the whole process, a large number of residual branches and rotten leaves will be produced, thus forming vegetable waste. These residual leaves are tail vegetables, commonly known as rotten vegetable leaves. Now many cities will be affected by the leftovers. On average, about one catty of leaves and roots will be discarded for one cabbage plant, and several tons of waste leftovers will be produced for about o...

Problems solved by technology

At the same time, a large amount of water is needed when cleaning the end dishes, resulting in a waste of water resources

Moreover, there are still a lot of pesticides and nitrite left in the tail vegetables processed into feed. From the perspective of food safety, these feeds cannot be used to feed poultry and livestock.

[0005] In addition, at present, farmers apply fertilizers and spray pesticides blindly. In order to ensure the control effect, they shoot insects whenever they see them, and often consciously increase the frequency of application.

When some illegal drug dealers sell pesticides, they bundle and prescribe large prescriptions, misleading farmers to use pesticides indiscriminately

There are also some farmers who are eager to control pests and prevent diseases. They are always worried about the types and dosages of pesticides guided by the agricultural technology and plant protection departments. They do not use them according to the dosage indicated on the label.

This will lead to a large amount of pesticide residues on the vegetable leaves, especially the tail vegetables. To recycle the tail vegetables, the problem of high concentration of pesticide residues must be solved first.
