Problems solved by technology

[0005] The main purpose of the present invention is to provide a production method of carbon-based synergistic compost. The technical problem to be solved is that the method can effectively return fruit tree waste to the field, reduce the pollution caused by its stacking and burning to the environment, and pass Adding a new material - biochar powder, overcomes the problems of rapid degradation of conventional compost in the soil, insufficient stable carbon into the soil and slow effect of improving soil fertility

Abstract

The invention relates to carbon-based synergistic compost manure as well as a production method and an application thereof. The production method of the carbon-based synergistic compost manure comprises the following steps: crushing waste branches of fruit trees into wood dust; doping and mixing the wood dust, a nitrogen fertilizer, excrement and biomass charcoal to obtain composting materials; composting the composting materials; and after completely composting, obtaining the carbon-based synergistic compost manure, wherein the use amount of the nitrogen fertilizer is based on pure nitrogen:the mass ratio of the wood dust to the nitrogen fertilizer to the excrement to the biomass charcoal is (40 to 45) to (3 to 8) to (30 to 35) to (15 to 20). According to the carbon-based synergistic compost manure, conventional composting materials and the biomass charcoal are commonly composted and are complementary to each other; and the biomass charcoal can be used for reducing the ammonia volatilization of conventional compost manure and keeping nutrients in the compost manure, so that a habitat and activity place for composting microorganisms is provided, the humification of the compostingmaterials is promoted, the content of humic substances in the compost manure is improved and the degradation of harmful substances in the compost manure is promoted. The conventional composting materials can be used for supplementing nutrients of the biomass charcoal and eliminating defects of high carbon and low mineral nutrients of the biomass charcoal.

Description

technical field [0001] The invention relates to the technical field of waste biomass resource utilization and organic fertilizer production, in particular to a carbon-based synergistic compost and its production method and application. A method of rotting to produce compost. Background technique [0002] Compost is an organic fertilizer that uses organic materials to ferment and decompose under the action of microorganisms. It contains rich nutrients and has a long and stable fertilizer effect. The ability, and mixed with chemical fertilizers can overcome the single nutrient contained in chemical fertilizers, long-term single use of chemical fertilizers will cause soil compaction, and the defects of water retention and fertilizer retention performance decline. At present, there are many organic materials used in conventional composting. Commonly used materials include plant primary residual biomass, such as crop straw, wheat bran, rice husk, vegetable stems and waste; and s...
