Rice planting method based on wheat straw returning to field

Abstract

The invention provides a rice planting method based on wheat straw returning to a field. The method includes the steps that crushing full doses of wheat straw to return to the field; using shallow water to soak the field, and conducting soil preparation through wet rotary tillage; when applying base fertilizers and tillering fertilizers, applying calcium peroxide or/and carbamide peroxide in a combining mode, and transplanting rice seedlings; at late rice tillering stage, ditching before field drying; carrying out field management until the rice matures. The rice planting method has the advantages of ecological environmental friendliness, effective utilization of farmland resources, improvement of soil environment and stable yield increase of the rice.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a rice planting method based on wheat straw returning to the field. Background technique [0002] Double cropping of rice and wheat is the main crop rotation method in Jiangsu's grain production, and full straw returning to the field is an important way to reduce environmental pollution and provide farmland resource utilization. In recent years, due to the extension of the growth period of rice varieties and the large-scale promotion of rice machine transplanting technology, the maturity period of rice has generally moved back, and the sowing of wheat has also been delayed, resulting in tight stubble. After returning to the field, under the condition of irrigation in the field, the uneven distribution of straw and the displacement of plowing equipment will also cause excessive accumulation of wheat straw in some areas. The water is hypoxic. At this time, drainage and water c...

Problems solved by technology

In recent years, due to the extension of the growth period of rice varieties and the large-scale promotion of rice machine transplanting technology, the maturity period of rice has generally moved back, and the sowing of wheat has also been delayed, resulting in tight stubble. After returning to the field, under the condition of irrigation in the field, the uneven distribution of straw and the displacement of plowing equipment will also cause excessive accumulation of wheat straw in some areas. The water is hypoxic. At this time, drainage and water change will pollute the river, and the green growth of rice after transplanting will be affected and even lead to stiff seedlings, yellow seedlings or even dead seedlings.
