Abstract
The present invention belongs to the field of farmland irrigation and the no water layer rice irrigating method features that water channels are dug in rice field at certain density for irrigation and drainage. While irrigation, water is replenished to rice field via the water channels to maintain moisture of soil while no water layer in the field. In area with relatively rich water source, rice seedling raising and transplanting in shallow water is adopted. In area with lack of water source, direct seeding, mulching covering and channel irrigation are adopted.
Description
The present invention relates to the field irrigation field, is a kind of invention of paddy rice irrigation method.
Traditional rice cropping is that deep water is irrigated, and can be described as " paddy rice paddy rice, support rice with water ".Advocate " light irrigation is diligent irritates " after the sixties, the water layer change " shallow ", but " duty " word makes the field face overwhelming majority times leave water layer, research promotion various rice water-saving irrigation techniques in various places since the eighties, but basically still based on the water layer irrigation.The paddy rice water layer is irrigated and is had following problem:
1, hinders root growth.The rice field is under long-term waterflooding condition, the soil severe depletion of oxygen, the gas concentration lwevel that is produced by root system and edaphon respiration increases, oxidizing potential descends, noxious materials such as excessive low price iron, manganese, rudimentary saturated fatty acid and hydrogen sulphide produce and accumulation, hinder the growth of root, even black root, mashed root take place.
2, the paddy rice of black root takes place, and the absorption of water is hindered, and Nutrient Absorption goes down, and photosynthesis can not normally carry out.The rice root development is bad, and the rice bar is weak easily to fall, and banded sclerotial blight, oriental sesame leaf pinta also takes place easily, cause the underproduction.This is the main factor that influences rice yield.
The purpose of this invention is to provide a kind of no water layer rice irrigating method, the solution paddy rice is dark excessively because of water layer, and floods oversize problem of field time, and makes this method be easy to again apply.
The approach that no water layer rice irrigating method is realized, and feature is described as follows: this method is to offer the little ditch of suitable density at rice field, double as " furrow irrigation ", " ditch row " dual-use function.It keeps the skin wet to soil by " furrow irrigation ", makes the field no water layer, but keeps moisture state.Different irrigation methods is adopted in the deficient area in more and water source at the water source.Adopt the method for " the wet pipe of water kind " in the area that water resource is more, promptly when rice transplanting, still have shoaling layer (the most handy non-irrigated seedling, well developed root system), and keeping water layer about 5 days, after the transplanting in order to turning green.After this field face no longer leaves water layer, but transfers " furrow irrigation " to.Need the water characteristic according to paddy rice,, soil moisture content is controlled between the 70%-100% of saturated water amount, to satisfy the paddy growth needs by regulating field water ditch water level.According to the paddy rice physilogical characteristics, it is the need water characteristic of different growing, making full use of on the basis of rainfall, with soil moisture content as control index, determine irrigation period, irrigating water quota, regulate soil moisture, oxygen, fertilizer, each key element of heat, give full play to paddy rice self regulative mechanism with " furrow irrigation ", impel paddy rice to develop to the direction of resistant to lodging, high yield, high-quality, this method can be saved duty about about 50%.
In the area of water resources shortage, then adopt the method for " dry planting and dry administration ", promptly adopt the non-irrigated seedling raising of " live " (program request, drilling all can).The land for growing field crops plastic mulching mainly utilizes the natural rainfall moisturizing, keeps ground moistening with mulch film, passes through " furrow irrigation " on a small quantity several times in case of necessity, and this method of artificial recharge " drought resisting " can be saved duty about 2/3.
No water layer rice is irrigated, and is for basining irrigation (water layer is arranged) for a long time, is not definitely can not " water layer be arranged ".For example the rice shoot of Yi Zaiing keeps 3-5 days shoaling layers, to promoting that rice striking root is favourable.Consider from the paddy rice water demand for natural service, " with water for cooling, with water insulation, fertile " with the water accent, these short time water layers also are useful and harmless.Certainly had multiple weed killer herbicide now, as long as the application process enemy, " pressing grass with water layer " there is no need.
The present invention does not increase production cost, only opens little ditch in the field more, make to irritate, row two is easy, also is that other high-yielding rice cultivation technique is desired, also according to the susceptibility of paddy rice different growing to water, determines the soil moisture content upper limit, lower limit and duty.Its meaning is: the paddy rice water consumption accounts for 50% of whole society's water consumption total amount, and has a large amount of wastes, and no water layer rice is irrigated can save great lot of water resources, is the shortcut of alleviating China's water scarcity contradiction, is again the important stain yield-increasing technology of controlling at southern area.
Claims (2)
1, a kind of no water layer rice irrigating method, it is characterized in that the paddy rice whole growing, the field face does not keep water layer, offer the little ditch of suitable density at rice field, double as " furrow irrigation ", " ditch row's " usefulness, it keeps the skin wet to soil by " furrow irrigation ", makes the field no water layer, but keeps moisture state.
2, no water layer rice irrigating method according to claim 1, it is characterized in that " furrow irrigation ", " ditch row ", be to adopt different irrigation methods with deficient area, water source by the water source is more, promptly adopt the method for " the wet pipe of water kind " in the more area of water resource, promptly when rice transplanting, still have shoaling layer, and keeping water layer about 5 days after the transplanting, after this field face no longer leaves water layer, but transfers " furrow irrigation " to; In the area of water resources shortage, then adopt the method for " dry planting and dry administration ", promptly adopt " live " non-irrigated seedling raising.
