Problems solved by technology

Physical improvement includes shallow plowing, cutting roots, cutting turf, etc. However, if the shallow plowing is too deep, it will easily cause wind erosion and the release of surface soil organic carbon in the early stage of improvement when the wind is strong in the grassland area. Therefore, the depth of plowing is a An important factor affecting the effect; chemical improvement includes irrigation and fertilization, etc., but the investment cost of irrigation and fertilization is high and the technology is complicated, so it is not suitable for large-scale promotion and application in grassland areas

Embodiment 1

[0034] In the 2012 growing season, the rainy grassland was implemented to improve the measurement of the degraded grassland, and the three -cricket plow degraded sheep grassland was used to loosen the soil. The effective depth of farming was 18 ± 2cm., Twelve -rounded to the ground, the effective depth of farming is 12 ± 2cm.Because the depth of farming is an important factor that affects the effect of improvement, it is easy to cause wind erosion and deepen, and the effect and purpose of not being improved.

[0035] In the third year of the processing, the data shows that the density and biomass of sheep grass population is not only largely increased by improvement, reducing the proportion of community miscellaneous grass (see Table 4), and reducing the weight of the surface soil, improving the soil of the soil, the soil.Vegetable water transparency (see Table 5).Among them, the density changes in the density of sheep grass behind the deep pine soil invented by this invention are...

Embodiment 3

[0049] In 1983, improvement measures were implemented for the degraded land of grazing. In the rainy season, the grazing grass grassland was cultivated with a deep plow of the grazing sheep grassland. The depth of farming was still 20 ± 2cm.The area of the area is parallel in the direction of farming twice. The data results of the second year after the analysis and improvement show that the same year after the deep rake of the grazing degenerate grassland with the three plows of the three plowsAlthough it can also reduce the surface capacity of the soil (see Table 8), it also largely improves the density and biomass of sheep grass population, but the effect is worse than the rake in the second year, and the proportion of community hypotemians is relatively high, Still reached 55.12%after processing (see Table 9).The comprehensive improvement effect is still the first year proposed by the topic of the topic of the top year, and the treatment measures for the use of heavy rake paral...

Abstract

The invention, which belongs to the technical field of soil improvement, discloses an improved method of deep digging of degenerated grazing leymus chinensis grassland at a grassland area. According to the improved method, one group of three-furrow ploughs and heavy harrows are dragged by a tractor to carry out smoothing improvement on manual soil loosening and clod crushing on the degenerated grazing leymus chinensis grassland. The improved method comprises: step 1, a tractor with the power larger than or equal to 80 horsepower drags one group of three-furrow ploughs to carry out soil loosening on the degenerated grazing leymus chinensis grassland at a rainy season at the first year, wherein the effective tillage depth is 18+ / -2cm; and step 2, reciprocating harrowing is carried out twice by using heavy harrows at the direction parallel to the tillage direction before the rainy season at the second year, wherein the effective depth is 12+ / -2cm. With the method, the soil can be loosened effectively; the soil porosity is increased and the soil bulk density is reduced. Meanwhile, the rootstocks of the chinese wildrye can be cut off to promote the sprout differentiation and growth, thereby accelerating the recovery and growth of the chinese wildrye.

Description

Technical field [0001] The present invention involves a method of recovering the human recovery of the hepheromed sheep grasslands. Specifically, the tractor traction a group of three -tap plows and heavy rakes to the method of human loose soil and soil crushing and tidal improvement of the grazing sheep grassland.Technical fields. Background technique [0002] Today, the main recovery measures for benign degenerative sheep grassland include: natural recovery, artificial improvement and recovery and reconstruction.Human improvement recovery includes two types: physical improvement and chemical improvement.Physical improvement includes shallow farming, cutting roots, cutting through grass, etc., but if the shallow plowing is too deep in the grassland, it is easy to cause wind erosion and surface soil organic carbon release in the early stages of improvement.Important factor affecting the effect; chemical improvement includes irrigation and fertilization, but the investment cost of...
