Problems solved by technology

Therefore, the application of organic livestock and poultry manure on the soil can effectively solve two problems: waste waste and low soil fertility
But animal manure added to soil directly contributes about 10% of global N 2 O emission; and some carbon will be degraded into CO 2 、CH 4 And other greenhouse gases are emitted into the atmosphere, thereby aggravating the greenhouse effect, and the carbon loss can be as high as 66.7%

Abstract

The invention discloses biomass charcoal-based organic fertilizer compost, and a preparation method and application thereof, and relates to the technical field of fertilizers. The biomass charcoal-based organic fertilizer compost comprises the following raw materials in parts by weight: 1-3 parts of rice straw biomass charcoal, 0.5-1.5 parts of pine wood chips and 6-8 parts of fresh pig manure. The biomass charcoal-based organic fertilizer compost disclosed by the invention can be used for rapidly increasing the content of organic matter in soil, improving the crop yield and reducing emissionof CH4 and N2O, and also has good adjusting functions on physical, chemical and biological properties of the soil. In addition, reasonable application of the organic fertilizer compost on red soil insouthern dry land can be guided, and formulation of greenhouse gas emission reduction measures on the red soil in the dry land can be guided, so that a good application prospect is achieved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to adding biomass charcoal to organic fertilizer compost, and utilizing biochar-organic fertilizer compost to form a biomass charcoal-based organic fertilizer product containing a large amount of elements, which is applied to soil. Background technique [0002] Red soil is the third largest soil type in my country. It is mainly distributed in the low mountains and hills south of the Yangtze River. The southern red soil area feeds 43% of the country's population with 28% of the country's arable land. However, the high temperature and high humidity in the red soil area lead to strong weathering and leaching of soil minerals and complete development, resulting in a lack of nutrients in the red soil and a decrease in soil fertility, which is not conducive to high crop yields, and the degree of nutrient degradation in dry land red soil is more serious than that in paddy field soil. T...
