Method for rapidly rotting composting of litter in the open in autumn / winter

Abstract

The invention relates to a method for rapidly rotting composting of litters in the open in autumn and winter, comprising the following steps of selecting field and then digging pit, collecting litters, sampling and calculating, composting litters and disposing. The method can sufficiently utilize ground temperature to greatly reduce the influence of external high temperature on composting temperature mainly by digging pit and underground composting; the effects of heat preservation, moisture preservation and fertility preservation are good; therefore, the activity of microbes to decompose flora can be ensured, thereby rapidly achieving the effect of rapidly rotting. The method solves the problems that the natural decomposition of litters is slow, the fire hazard is outstanding and the latent nutrient runs off in artificial forest in northwest arid area and meanwhile is not limited by climate and field, thereby solving the problems existing in circulation of substances and nutrient balance of the ecological system of the artificial forest in northwest arid area. The invention provides a new method for a near nature managing and protecting technique of the artificial forest.

Description

Technical field:

[0001] The invention relates to a method for quickly decomposing litter in the open air in autumn and winter, and in particular to a rapid decomposition technology for woodland litter in temperate arid and semi-arid regions. Background technique:

[0002] In the northwest of my country, in order to improve environmental conditions, reduce natural disasters, and protect urban safety, a large area of ​​artificial ecological protection forest has been built around the city. However, due to the severe constraints of natural conditions such as drought, lack of rain, and dry climate, the litter in the forest land decomposes naturally It is very slow, which seriously restricts the material circulation, nutrient balance and improvement of forest soil fertility in the forest ecosystem, and the healthy growth of trees and the stability and sustainability of forest land are seriously threatened. In addition, with the gradual accumulation of undecomposed litter on the su...
