Abstract

The invention discloses a method for building and / or maintaining a high-standard farmland rich in humus. The method comprises the following steps: (1) carrying out enzymolysis on crop straws containing surface active compound enzyme to obtain humus; (2) supplementing the humus into the farmland; in the surface active compound enzyme, the mass ratio of cellulase to hemicellulase to protease to hydrolase to oxidoreductase to esterase is (8-12): (3-7): (18-22): (28-32): (28-32): (13-17). The method for building and / or maintaining a high-standard farmland rich in humus is suitable for various crops such as food crops, vegetables and ornamental plants, and the residual rate of mulching films and pesticides can be effectively lowered.

Description

technical field [0001] The present invention relates to a method of building and / or maintaining high-standard farmland rich in humus. Background technique [0002] Cultivated land is the material basis of food production, and the construction of high-standard farmland is an important measure to ensure China's food security. The delineation of high-standard farmland is slightly different from place to place, and the comprehensive score for calculating high-standard farmland = contiguousness score x weight + financial support score x weight + grain production capacity score x weight + cultivated land consolidation potential score x weight . Among them, the grain production capacity score and the cultivated land consolidation potential score are the most important. [0003] In 2014, the "General Rules for High-standard Farmland Construction" (GB / T30600—2014)'2 jointly formulated by the Ministry of Land and Resources and the Ministry of Agriculture'2] combined high-standard fa...
