Description

Foliar fertilizer taking edible fungus residues and tangerine peel and citrus pulp residues as raw materials and preparation method thereof
Technical Field
The invention relates to the field of agricultural fertilizers, in particular to a foliar fertilizer, and particularly relates to a foliar fertilizer taking edible fungus residues and tangerine peel and citrus pulp residues as raw materials and a preparation method thereof.
Background
The edible fungus slag is a waste solid culture medium after the production of edible fungi, the scale for producing the edible fungi in China is huge, the quantity of the edible fungus slag is increased sharply along with the development of the edible fungus industry, but the utilization rate is low and is about 35 percent. The edible fungus dregs are generally rich in protein, crude fat, crude fiber and trace elements, and also contain bioactive substances such as polysaccharide, organic acid, enzyme and the like, and a large amount of fungus dregs are not treated in an environment-friendly way and are discarded at will, so that not only is the resource waste caused, but also the fungus dregs are easy to go moldy and deteriorate, pollute land and water sources and harm the health of human bodies.
At present, the main utilization approach of the edible fungus residues is to prepare organic fertilizer by stacking, use the organic fertilizer as an edible fungus cultivation material and a feed after treatment, but the comprehensive utilization is low and the effect is poor. The method for preparing the organic fertilizer by adopting the edible fungus residues mainly comprises two modes, wherein one mode is that the edible fungus residues are all used as raw materials, the organic fertilizer is prepared by stacking fermentation, the fermentation time is more than 30 days, and the nutrition in the organic fertilizer is single; one method is to add a small amount of the edible fungi residue into other raw materials to prepare an organic fertilizer, and the problem of low utilization rate of the edible fungi residue cannot be solved due to the small amount of the edible fungi residue. The edible fungus slag can not be fully utilized, so that the waste is turned into treasure and is discarded at will, which not only causes serious environmental pollution to the producing area of the edible fungus, but also wastes resources. Therefore, the comprehensive and efficient utilization of edible fungus resources is a common requirement for protecting the environment and saving resources.
In recent years, tea products prepared by using tangerine peel and tangerine peel are more and more popular, such as citrus-common tea in Xinhui city of Guangdong province. The tangerine peel and tangerine peel tea is divided into two types, one is a product prepared by mixing tangerine peel prepared from small green tangerine oranges and Yunnan Pu' er ripe tea, and the other is prepared from ripe large tangerine peel oranges. In any case, a large amount of byproduct citrus pulp residues are generated in the manufacturing process, and because the acidity of the citrus pulp is high, the citrus pulp residues are wasted in large quantity at present, and an effective solution is not provided at present. According to statistics, ten thousand tons of tangerine peel meat residues are required to be subjected to environment-friendly treatment every year in Xinhui county of Guangdong province, and if the tangerine peel meat residues can be comprehensively utilized, the method is beneficial to environment and resource reutilization.
