Biological organic fertilizer applied to greenhouse vegetables

Abstract

The invention discloses a biological organic fertilizer applied to greenhouse vegetables, and belongs to the field of biological organic fertilizers. The biological organic fertilizer applied to the greenhouse vegetables is prepared from the following preparation steps that 1, chicken dung and chicken feathers are collected separately for standby application; 2, the chicken feathers are washed anddisinfected, after drying, the soft parts of the chicken feathers are taken to be weaved into a bag-shaped chicken feather bag, and the remaining hard parts are reserved for standby application; 3, material inoculation and pre-fermentation are conducted; 4, evenly mixing is conducted in a mixer after composting; 5, the finished product of solid manure is obtained after granulation, drying, cooling, and screening; and 6, the 'chicken feather bag' is used for wrapping the finished product of solid manure and sealing to obtain the final biological organic fertilizer. The chicken feathers are used for making the 'chicken feather bags' of different sizes to wrap the finished product of solid manure inside the chicken feather bags, compared with a traditional organic fertilizer, according to the biological organic fertilizer, on the one hand, the organic fertilizer can be fully utilized, on the other hand, environmental pollution brought by the use of additional packaging bags can be avoided, 'bagless' packaging is realized, and meanwhile quantitative manure application is further facilitated.

Description

technical field [0001] The invention relates to the field of bio-organic fertilizers, in particular to a bio-organic fertilizer applied to vegetables in greenhouses. Background technique [0002] With the development of animal husbandry, the problem of livestock and poultry waste pollution has become increasingly prominent. Improper handling of livestock and poultry manure not only wastes a lot of organic fertilizer resources, but also pollutes the environment. Among them, nutrient loss, odor pollution, surface water and groundwater pollution during chicken manure stacking are the main manifestations. [0003] At present, there are only two aspects to the harmless treatment and resource utilization of chicken manure in my country. One is to provide bioenergy through biogas fermentation, and the other is to use it as organic fertilizer. The harmless treatment methods mainly include: (1) Direct drying mode, the chicken manure is spread out manually to dry, after drying, it is...

Problems solved by technology

(3) The biological fermentation mode mainly adopts fermentation tank fermentation, direct composting, tower fermentation, etc. The advantages of fermentation tank fermentation are simple process, less investment, and low cost. The main problem is that the product stacking time is too long; tower fermentation occupies an area The area is small, the energy consumption is low, and the pollution is small. The problem is that the cost is high and the equipment corrosion is serious.

[0005] The existing solid manure products are generally packed in a sack or plastic packaging bag. When fertilizing, the solid manure product in the bag needs to be poured out. It is difficult to control the amount applied. In addition, the solid manure product in the bag is poured out. Finally, people usually throw away the packaging bags or bury them in the ground with chicken manure. However, no matter whether they are littered packaging bags or directly landfilled packaging bags, they are difficult to degrade, causing certain environmental pollution. In addition, Whether it is a littered bag or a bag that is directly landfilled, it is an unnecessary waste
