Novel degradable nutritional type growing tray manufactured by using pig manure

Abstract

The invention provides a novel degradable nutritional type growing tray manufactured by using pig manure. The novel degradable nutritional type growing tray manufactured by using the pig manure is prepared from the following method, and the preparation method comprises the steps that (1) the dry basis pig manure is exposed to the sun, moisture is reduced within 10%, and the dry basis pig manure issmashed into 30-80 mesh powder; (2) the smashed dry basis pig manure is stirred with microbial species and saccharomycetes, water is added, the moisture of the dry basis pig manure is increased to 25-30%, and microbial fermentation is carried out to make into dry basis pig manure powder; (3) ultramicro grinding is carried out to obtain ultramicro dry basis pig manure powder with the mean grain size of 4-7 [mu]m; (4) the ultramicro dry basis pig manure powder and starch glue are placed into a mixer, and uniform mixing is carried out to obtain raw materials; and (5) the raw materials are placedinto a growing tray mould to pressed into the growing tray. According to the novel degradable nutritional type growing tray manufactured by using the pig manure, the growing tray manufacturing raw materials and technology are very environmentally friendly, the obtained growing tray can promote seeds to sprout and grow, nutritional ingredients can be provided for seedlings, the rate of absorptionand utilization is high, after seeding is completed, the growing tray can be buried into the earth and used as slowly released base fertilizers, and soil nutrients are enhanced.

Description

technical field [0001] The invention relates to the technical field of seedling raising, in particular to a novel degradable nutritional seedling raising tray made of pig manure. Background technique [0002] The seedling tray is a device for cultivating rice and other crop seedlings. Using the seedling tray to transplant and transplant the seedlings can make the seedlings take root deeply and improve lodging resistance. The seedlings are thick and the survival rate is improved. In addition, the seedling tray is used to facilitate mechanical transplanting, saving manpower and capital investment. [0003] Traditional seedling trays are made of plastic injection molding. Although they can be used continuously, the plastic products themselves are refractory substances. Long-term use will bring great pollution to the environment. Plastic seedling trays require additional Add soil and nutrients to supply the energy needed for seedling seedlings. Every year when seedlings are rai...

Problems solved by technology

[0003] Traditional seedling trays are made of plastic injection molding. Although they can be used continuously, the plastic products themselves are refractory substances. Long-term use will bring great pollution to the environment. Plastic seedling trays require additional Add soil and nutrients to supply the energy needed for seedling seedlings. Every year when seedlings are raised, many farmers have to dig the soil for mesh filtration. The fine soil is sifted out as the soil for seedlings. It not only destroys the ecology but also has a cumbersome process. Under increasingly stringent policies, the raw materials and techniques for making seedling trays should be environmentally friendly and develop in the direction of ecological cycles.
