Abstract

The invention relates to the technical field of improvement and fertilization of soil, in particular to a green fertilization method for reclaimed land. The green fertilization method for the reclaimed land includes the steps of: screening out gravel in soil of the land which is obtained from a reclaimed house site, crushing mushroom residues, and modifying the reclaimed soil by using the crushedmushroom residues and urea, wherein modification comprises the steps of: mixing the mushroom residues and topsoil 5-7 days before sowing of spring crops and late-autumn crops is conducted, 1-2 days before sowing of the spring crops and late-autumn crops is conducted, applying urea, and covering the soil with the mushroom residues; and in a period between spring and late autumn, mixing the mushroomresidues with the topsoil. Through adoption of the green fertilization method for the reclaimed land, organic matter of 0-20 cm of the soil of the reclaimed land can be promoted and improved by 12.9%per year on average, the content of N, P and K is improved by 6.2-10.4% under the action of promotion, the volume weight is reduced by 3.6-6.9%, the field moisture capacity is increased by about 2.8-3.8% on average, and the annual yield of wheat, corn and other crops is increased by 3.6-5.5%.

Description

technical field [0001] The invention relates to the technical field of soil improvement and fertilization, in particular to a method for green fertilization of reclaimed land. Background technique [0002] China's per capita arable land area is less than 40% of the world's average level. There are many people and little land, and the land pressure is very huge. The government of our country has carried out the homestead reclamation project to reorganize and reclamate the scattered, idle and abandoned homesteads that are improperly allocated and used unreasonably in rural areas, making them arable land resources. However, the homestead reclaimed soil has more bricks and stones and poor soil nutrient status, which leads to the loss of the original function and characteristics of the soil, resulting in low crop yield and quality. However, the current fertilization technology after homestead reclamation mostly uses excessive organic materials and inorganic fertilizers, and the ...
