Reasonable method for constructing plough layer of plough land of red soil slope

Abstract

The invention belongs to the technical field of agricultural production, and discloses a reasonable method for constructing a plough layer of plough land of a red soil slope. For the increasingly-prominent problems, of plough layer soil thinning and soil hardening, caused by unreasonable tractor-ploughing and extensive management of the plough land of the red soil slope, methods of deep scarification and optimal configuration of deep-rooted and shallow-rooted crops are adopted; for the problems, of nutrient loss and ecological environment destruction, caused by serious water and soil loss of the plough land of the red soil slope, biological trapping and protective ploughing methods are adopted; and for the problems of acidification aggregation, poor nutrients and a poor structure of red soil, methods of fast decomposition and returning to land of straw, a soil amendment and a conditioner are adopted. According to the reasonable method for constructing the plough layer of the plough land of the red soil slope, reasonable plough layer constructing technologies of red soil slope plough land plough layer thickening ploughing, plough layer thickening water conservation, plough layer nutrient activation and the like are completed, the structure of the plough layer of the plough land of the red soil slope is improved, crop yields are raised, and the net incomes of farmers are increased.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and in particular relates to a method for constructing rational plow layers of red soil sloping cultivated land. Background technique [0002] At present, the sloping cultivated land in the red soil area accounts for more than 70% of the dry land area. It is an important agricultural production resource in the red soil area in the south. The abundant water and heat resources make the agricultural production and economic development potential in this area huge, and it undertakes the dual tasks of increasing production and income and environmental protection. duty. However, for a long time, factors such as single planting system, irrational use of land, soil compaction and shallow plowing layer caused by long-term mechanical rotary tillage have resulted in low production levels and economic benefits of red soil sloping farmland, which has become a bottleneck restricting agricultural...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problems existing in the prior art are: the unitary planting system and irrational use of land in the southern red soil area, etc., resulting in low production level and economic benefits of the red soil sloping farmland, which has become a bottleneck restricting the agricultural development of the southern red soil area. Shallow soil, serious water and soil erosion, and unreasonable planting methods are the key obstacles to the construction of a reasonable cultivated layer on red soil slope farmland. The research on deep loosening technology of deep and shallow root crops intercropping and ridge farming is blank

[0004] The difficulty and significance of solving the above technical problems: There are many studies on the physical and chemical properties of soil and crop agronomic properties for intercropping and ridge cultivation alone, but there are relatively few studies on the combination of these two techniques. Different crops have complementary advantages in terms of spatial distribution and nutrient requirements, and can effectively use various growth factors to obtain yield advantages, which plays an important role in promoting sustainable agricultural development
