Soil rotation tillage corn planting method suitable for semi-arid regions

Abstract

The invention discloses a soil rotation tillage corn planting method suitable for semi-arid regions. All corn straw is returned to the field by taking three years as one period, a turning-over, rotation tillage and no-tillage mode or a rotation tillage, no-tillage and no-tillage mode is used, soil fertilizing is completed by means of a reasonable straw returning strategy, accordingly the yield of crops is effectively increased, and soil degradation and fertilizer and water loss are prevented; besides, shallow tillage and no-tillage are partly used so that the cultivation cost can be effectively reduced, and the efficiency of cultivation is improved; the straw can be recycled or returned to the field so that air pollution caused by incineration of the straw can be avoided, and the utilization efficiency of farmland resources is improved; by the adoption of the ridge planting method, groundwater can be conveniently used for irrigation in summer, so that the harvest benefits of different years in the semi-arid regions are guaranteed, and therefore the method has relatively high practical value.

Description

technical field [0001] The invention relates to the technical field of soil rotation cultivation, in particular to a corn planting method suitable for soil rotation cultivation in semi-arid areas. Background technique [0002] The quality of soil fertility directly affects the yield of crops. In the traditional agricultural production process in my country, it is generally used to plant a single crop all year round for tillage production. However, tillage will lead to reduced soil water storage capacity, serious soil erosion and salinization, and high organic matter loss. problems, which in turn lead to rapid soil degradation, continuous reduction in crop yields, and long-term cultivation of the same crop will also lead to reduced microbial content in the soil, serious pests and other problems. [0003] The western part of the Northeast Plain in China is mainly a dry farming area, but it is the main corn producing area in my country. The long-term single planting of corn has ...

Problems solved by technology

[0002] The quality of soil fertility directly affects the yield of crops. In the process of traditional agricultural production in my country, a single crop is generally cultivated through perennial plowing, but plowing will lead to reduced soil water storage capacity, serious soil erosion and salinization, and high organic matter loss. problems, which in turn lead to rapid soil degradation, continuous reduction in crop yields, and long-term farming of the same crop will also lead to problems such as reduced microbial content in the soil and serious pest infestation

[0003] The western part of the Northeast Plain in China is mainly a dry farming area, but it is the main corn producing area in my country. The long-term single planting of corn has led to heavy use of land and light cultivation. The yield has declined year after year, and the quality of corn has continued to decrease, which has seriously damaged my country's agricultural development. In recent years, with the continuous exploration of farming methods, people have realized that reasonable rotation cultivation can effectively restore soil fertility, reduce crop diseases and insect pests, and can effectively reduce soil cultivation costs. If the soil quality and climate characteristics of semi-arid areas can be used , designing a high-efficiency rotation method can effectively improve the agricultural production efficiency in the Midwest and reduce the cost of agricultural production. For this reason, we provide a method for planting corn in the semi-arid area soil rotation
