Fallow crop rotation, wind-proofing and moisture-preserving method for cultivating corn

Abstract

The invention belongs to the agricultural technique field and relates to a method of crop rotation with no tillage, windbreak and water-holding for corn, comprising: changing the traditional tillage ridge to super large ridge, with the distance between large ridges being 1.6-1.7 m, the distance between small ridges 0.3-0.4 m, the large ridge and small ridge form the large-small ridge cultivation pattern of two rows with the width being 2 m. The large ridge is shared into three 36-37 cm distances and two 0.3-0.4 m distances, sowing two rows of corn in the small ridge with the distance between each other being 36-37cm in each year, unrepeated sowing of corn for two-year in 0.3-0.4m small ridge in the large ridge with the width being 1.6-1.7m, repeating the first year sowing in the small ridge in the fourth year. Leaving stubble with the height being 35-40 cm when recovering the corn and putting the whole straw in the middle of the small ridge uniformly.

Description

technical field [0001] The invention belongs to the farming system and cultivation method in the field of agriculture, and relates to the fallow crop rotation after changing the ridge direction and expanding the ridge spacing, in particular to a method for corn fallow crop rotation and windproof and water retention. Background technique [0002] Due to the high population and low land in some places, the land cultivation index is extremely high, and due to the requirements of food supply, it is impossible for any land to fall fallow. Continuous tillage will gradually reduce the soil quality, and the soil fertility will not be restored, and because only planting but not raising, and only chemical fertilizers are applied instead of organic fertilizers, the land will be compacted, the physical properties will deteriorate, the organic matter content of the soil will decrease year by year, and the soil quality will gradually deteriorate. . There has been a vicious cycle in which...

Problems solved by technology

Continuous tillage will gradually reduce the soil quality, and the soil fertility will not be restored, and because only planting but not raising, and only chemical fertilizers are applied instead of organic fertilizers, the land will be compacted, the physical properties will deteriorate, the organic matter content of the soil will decrease year by year, and the soil quality will gradually deteriorate.

There has been a vicious cycle in which chemical fertilizers alone are used to increase production, which seriously restricts the sustainable development of agriculture and endangers food security and social stability
