Rice three-free cultivation method for paddy field

Abstract

The invention discloses a rice three-free cultivation method for the paddy field. The rice three-free cultivation method comprises the following steps of treating straws of previous harvested crop, performing ridging, transplanting rice, adding earthworms, performing field management, and after rice is harvested, performing three-free circular planting. Ridging is performed in the paddy field, water is stored in furrows, and the rice is planted on ridges, so that the roofs of the ridges are maintained to be moist and free from water; through shielding of the rice, before ridging, an organic fertilizer is basally applied, full dose of the straws are returned to the field, and the roofs of the ridges are covered with the straw, so that favorable places and rich baits are provided for growthand propagation of the earthworms, and self-reproduction of the earthworms in the paddy field is realized. The earthworms are bred in the paddy field, so that the content of nitrogen, phosphorus, potassium and the like in the soil are increased, and the problems of sealing of soil, secondary gleyization and the like can be solved; through the furrows, the water storing and draining capacity of thepaddy field can be improved, the utilization efficiency of natural rainfall can be improved, and three-free operations namely free from tillage, free from straw burning and free from irrigation of the field, in the production course of the rice, are realized, so that the energy consumption during operation is reduced, the irrigation water is reduced, and haze is reduced.

Description

technical field [0001] The invention relates to rice cultivation technology, in particular to a three-free (no-tillage, no-burning straw, and no-irrigation-soaking field water) cultivation method for rice in a paddy field. Background technique [0002] At present, there is still extensive production in my country's rice cultivation, that is, a large amount of pesticides and fertilizers are invested to obtain high yields. While extensive production has brought about an increase in rice production, its cumulative effect of "reverse ecologicalization" has also become increasingly apparent, especially in the form of increased agricultural non-point source pollution, declining soil fertility, declining product quality, and frequent food safety issues. Chemical fertilizers and pesticides are used in large quantities and have low utilization rates, and have become the main sources of agricultural non-point source pollution. Agricultural production is overly dependent on the use of...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a rice field that can realize the symbiosis of rice and earthworms, and rice planting can realize no-tillage, no-burning of straw, and no-irrigation of field water for the problem that conventional rice planting and earthworm growth cannot coexist.
