Method for preparing organic nutrient soil by using greenery wastes

Abstract

The invention discloses a method for preparing organic nutrient soil by using green plant waste, which comprises the following steps: placing the green plant waste in the form of powder in a closed greenhouse, and a drainage groove is arranged in the greenhouse; waste green plant The carbon-nitrogen ratio of the mixture is controlled at 25:1-35:1, and then mixed with fermented water containing compound fermentation bacteria at 25-35°C; the fermentation mixture is fermented in a closed environment at a temperature of 50-65°C; During the process, the water content of greening plant waste is 40-55%, fermented for 14-20 days to form fermented organic matter; take organic matter, cottonseed cake powder, bran, peat and loam, pulverize and mix, add water to 25-30% of the total weight, adjust the pH value to 7.5-8.5; mix the mixture with high-temperature microbial strains, then add clean water, stir and mix well, and make a pile. Keep the pile at 60-70°C. After 15- After 20 days of fermentation, the temperature of the heap is lowered to below 40°C, the heap is spread out, and the decomposed material is obtained after natural drying.

Description

technical field [0001] The invention relates to a method for preparing organic nutrient soil by utilizing greening plant waste. Background technique [0002] During the growth of green plants, plant waste materials such as litter and leaves produced by natural regeneration or tree and shrub trimmings, lawn trimmings, discarded grass flowers and weeds generated during greening maintenance become garbage. The disposal of these garbage Often becomes a big problem. [0003] At present, there are several traditional treatment methods for greening plant waste, some are composted as organic matrix, used as mulch to improve and repair soil, and some are incinerated or landfilled. However, with the increasing requirements for greening environment and the rising rate of greening, there is an increasing problem of disposal of greening plant waste. If the traditional incineration or landfill method is used, it will undoubtedly cause great damage to the environment, and it is also a wa...

Problems solved by technology

However, with the increasing requirements of the greening environment and the increasing greening rate, there are more and more green plant wastes to deal with.

If the traditional incineration or landfill method is used, it will undoubtedly cause great damage to the environment and a waste of resources.
