No-tillage cultivation method of early rice in winter fallow field

Abstract

The invention discloses a no-tillage cultivation method of early rice in a winter fallow field. The method includes the following steps that after late rice is harvested, straw in the field is reserved, in winter, dried rice tubes are reserved, and the growth of weeds is promoted; in the next year, at least 500 adult ducks tread the weeds twice to form an ecological blanket prototype composed of the weeds, mud, duck manure and unrotten straw; a lever type grass press plate is adopted to act on the weeds and unrotten straw in the ecological blanket prototype to form an ecological blanket, and ecological planting holes used for sowing and ecological fertilizer holes used for fertilization are formed in the ecological blanket, so that the ecological blanket is constructed as an ecological hole blanket; under the no-tillage and no-irrigation conditions, sprouted rice seeds are sown in the ecological planting holes and then covered, a fertilizer is applied in the ecological fertilizer holes and then covered; on the basis of conventional field management, when the rice enters the early tillering period, young ducks are placed in the field for preventing and controlling diseases, pests and weeds, a compound fertilizer is applied in the active tillering period, the compound fertilizer is applied again in the booting stage, and then the no-tillage cultivation of early rice in the winter fallow field is completed. The method improves the utilization rate of chemical fertilizers and reduces the amount of water used in the field and the use amount of pesticides.

Description

Technical field [0001] The invention relates to the field of rice cultivation, in particular to a no-tillage cultivation method for early rice in winter fallow fields. Background technique [0002] According to statistics, in 2016, the use of chemical fertilizers and pesticides in China reached 60 million tons (equivalent to pure) and 300,000 tons (equivalent to 100), but the fertilizer utilization rate was only about 35%, and pesticide residues were large, which led to soil degradation and nutrients. A series of problems such as loss, waste of resources, environmental pollution, and low product quality. At the same time, China’s total agricultural water consumption is 372 billion m 3 , But the total water consumption for rice reaches 241.8 billion m 3 (The total water consumption for rice accounts for about 65% of the total agricultural water consumption); the sown area of ​​rice is about 452 million mu, and the plowing of rice fields generally requires 150 m2 of water for soaki...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the problems of idle winter fields, shortage of water for soaking fields, large amount of chemical fertilizers, time for top dressing, and unreasonable use of pesticides, etc.; at the same time, in order to avoid the poisonous effect of fertilizer base application on rice seedlings, realize rational utilization of winter idle fields and save water for soil preparation and soaking , improve the emergence rate and fertilizer utilization rate of upland rice, the present invention provides a no-tillage cultivation method for early rice in winter slack fields, which can save water for field preparation, reduce the amount of chemical fertilizers at the same time, and avoid the poisonous effect of fertilizer base application on rice seedlings, Improving the Emergence Rate and Fertilizer Utilization Efficiency of Dry Rice Plants
