Abstract

The invention discloses a method for preparing degradable agricultural mulches by reusing organic waste residues of biomass, which can be widely used for preparing biodegradable nutritional type water-retention mulches by recycling the by-product residues in the fermentation brewing industry and the sugar industry. In the process, low-concentration alkali liquor is mainly used for processing the waste residues, specified neutralizing agents are used for neutralizing the fertilizers such as N, P, K and the like required for growing the plants which are generated and auxiliary film-forming agents, plasticizers and the like are used for preparing mulch stock solution, or casting or diluting or spraying is carried out. The mulch is low in cost and convenient to operate, such substances as pesticides, weedicides, trace fertilizers and the like can be added to the mulch according to the requirements of different crops, and the mulch not only has the effects of heat preservation, moisture preservation and fertilizer betterment but also has moderate degradation period. The degradation rate of the ground mulch reaches 55-70% after 4 months and almost reaches 100% after about 8 months.

Description

technical field

[0001] The invention relates to a method for preparing biodegradable agricultural mulch by reusing biomass organic waste, in particular for the comprehensive reuse of by-product residues in fermentation brewing industry and sugar industry to prepare biodegradable mulch, which belongs to the application of agricultural production field. Background technique

[0002] Mulch film: the ground covering film, usually transparent or black PE (polyethylene) or PVC (polyvinyl chloride) film, used for ground covering to increase soil temperature, maintain soil moisture, maintain soil structure, and prevent pests from invading crops and certain Diseases caused by some microorganisms, etc., have the function of promoting plant growth. However, the degradation time of this kind of plastic film is as long as 200 to 300 years. With the extensive application of this non-degradable plastic film, its residual film will accumulate in the soil more and more, which will reduce th...
