Embodiment 1

[0053] A method for adjusting the carbon-nitrogen ratio of plateau grassland soil, comprising the following steps:

[0054] S1: raking the grassland to be treated and forming ridges, the raking depth is 20cm, the ridge height is 20cm, the ridge width is 20cm, and the ridge spacing is 40cm.

[0055] S2: Take the highland barley straw, cut it into a 20cm long straw section, then soak the straw section in lime water with a pH value of 14 for 20min, remove and drain until the water content is 60%, and then spray 30mL of 1Kg straw section to decompose Spray the decomposing agent solution on the straw section, and finally stack the straw section into a haystack with a growth of 2-3m, a width of 2-3m, and a height of 1-1.5m, and then cover the haystack with a film, and naturally pile it for 10 days. Complete decomposing; the decomposing agent used when preparing the decomposing agent solution includes the following components by mass: 50 parts of Bacillus subtilis, 25 parts of saccha...

Abstract

The invention discloses an adjusting method of a soil carbon-nitrogen ratio of a plateau grassland. According to the method, the to-be-processed grassland is firstly raked, ridges are formed, a carbon-nitrogen adjusting base material obtained by the mixing of thoroughly decomposed straw and a carbon fertilizer is spread in the ridges, a carbendazim solution with the concentration of 600-800 mg / L is sprayed on the carbon-nitrogen adjusting base material, soil on ridge boxes are buried to the ridges, so that the carbon-nitrogen adjusting base material is completely covered with soil, and the thickness of a soil covering layer on the carbon-nitrogen adjusting base material is 5-10 cm; the grassland is raked again after 10-15 days to allow the carbon-nitrogen adjusting base material to be uniformly mixed with soil blocks in the grassland, and the carbon-nitrogen ratio adjustment is completed. By means of the method, the problem of carbon-nitrogen disproportionality on the plateau grasslandcan be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of soil quality improvement, and in particular relates to a method for adjusting the carbon-nitrogen ratio of plateau grassland soil. Background technique [0002] Carbon and hydrogen are the two most important elements in plants, and their content accounts for more than 50% of the dry weight of plants. Carbon is equivalent to human bones for plants, and plays a supporting role for plants; nitrogen is equivalent to human muscles for plants, playing a strengthening and auxiliary role. A moderate ratio of carbon and nitrogen is not only beneficial to crop growth, but also can control the excessive growth of plants. [0003] The plateau area has less vegetation and less natural organic humus, which cannot effectively supplement carbon and nitrogen. In addition, in order to ensure the normal growth of plateau grassland crops, a large amount of organic nitrogen and inorganic nitrogen have been invested year afte...
