A kind of early rice cultivation method based on winter planting green manure

Abstract

The invention discloses an early season rice cultivation method based on winter planting green manure. The method comprises the steps that before late rice harvesting, green manure seeds are evenly sprayed into a rice field before late rice harvesting, after late rice harvesting, a channel is dug in the rice field for drainage, the field surface is kept in the waterless and shallow water state in the channel in winter; in the second year, an ecological blanket rudiment composed of green manure, sposh, duck manure and unrotten straw is formed in the field surface after at least 500 elder ducks step on the green manure for 5 d continuously; then, a prying type grass pressing plate is adopted for acting on the green manure and unrotten straw inside the ecological blanket rudiment to form an ecological blanket, and an ecological seed hole for seed sowing and an ecological manure hole for fertilization are formed inside the ecological blanket, so that the ecological blanket is constructed into an ecological hole blanket; in the tillage-free and irrigation-free state, chest breaking rice seeds are sown inside the ecological seed holes and are covered, and fertilizer is applied to the ecological fertilizer hole, and a cover is arranged; on the basis of regular field management, when rice grows to the tillering stage, duckling control disease and pest weed is put, topdressing of compound fertilizer is performed at the active tillering stage, and topdressing of compound fertilizer is performed again at the booting stage.

Description

technical field [0001] The invention relates to the field of rice cultivation, in particular to a method for cultivating early rice based on winter-planted green manure. Background technique [0002] At present, the area of ​​winter idling fields in the south has exceeded 100 million mu, and there is a trend of further expansion; the idling of winter rice fields has caused great losses to local agricultural production resources. Substantial reductions in dosage, unreasonable fertilization ratios and methods have directly led to the shallowing of the paddy field cultivation layer, the decrease in organic matter content, the loss of nutrients, the decline in product quality, the aggravation of environmental pollution, and the deterioration of soil physical and chemical properties, which restrict the sustainability of paddy field soil. production capacity. After the green manure planted in winter is mature, it needs to be turned over and returned to the field in time, and the ...

Problems solved by technology

[0004] In order to realize the light and simple return of winter planting green manure to the field, and to overcome the problems of large amount of chemical fertilizer, unreasonable fertilizer application, increased use of pesticides, and shortage of irrigation water; Dry seed emergence rate, the present invention provides a winter-planted green manure-based early rice cultivation method, which can save water for soil preparation, reduce the amount of chemical fertilizers, improve the utilization rate of chemical fertilizers, and achieve fertilizer and water conservation.
