CN101803547A - Direct seeding technology of China agricultural rice growing - Google Patents

Abstract

The invention relates to a direct seeding technology of China agricultural rice growing, which is a technology as follows: when being grown, rice seeds are directly seeded into large rice field, and are transplanted to a big field without need of raising rice seedlings in the field. In regardless of a dry-seeding method, a wet-seeding method or interplanting, the direct seeding technology saves time, water, fertilizer, pesticide, money, labor and worry compared with the traditional old growing method of transplanting the rice, and the yield also can be increased by 10 percent to 20 percent for per mu.

Description

The direct seeding technique of Chinese agriculture paddy rice plantation

(1) technical field

The present invention relates to the direct seeding technique of a Chinese agriculture paddy rice plantation

(2) background technology

It is constant that the planting technology of Chinese agriculture paddy rice often follows traditional ancient pattern, not only consuming time, but also effort, particularly everyly broadcast seedling nationwide mobilization especially in season, very so-called " yellow seedling lands, the old and the young bow ", " facing the loess back of the body " towards the sky hindered greatly rural productivity further with development.

(3) summary of the invention

The present invention provides the direct seeding technique of a Chinese agriculture paddy rice plantation to hundreds of millions peasants in the vast rural area of the whole of China, what is called is live to be exactly that the seed rice of paddy rice is directly sowed in large stretch of farmland of growth paddy rice, tooth is sent out in growth does not need seed soaking in the past, seal kind, sow, seedling, play seedling, manual labor that these are heavy and technology, the benefit of this technology is to save time, water-saving, economize fertile, economize medicine, the saving of labor, save money, economize the people, save worry, results are big, every mu can be increased production 1-2 and become income many, every mu can to increase more than 200 yuan of RMB rice matter good, every mu of dosage reduces half, and the chance of pollution is few:

Though use the direct seeding technique of this paddy rice convenient and simple, fast where the peasant at a glance can, can grasp once saying, roughly experience as the next stage.------later management as usual is until harvesting to spread and spill agricultural chemicals--sow seed rice--go up water infiltration--for following sufficient base manure in smooth rice field for real tillage.This rice direct-seeding technology that is is that rural area, Chinese the greater part plantation double cropping paddy rice has been established solid technical foundation, use the direct seeding technique of this paddy rice can also carry out wheat rice interplanting interplanting, the first rice crop interplanting interplant two season rice, but in Hainan, Fujian, area, Guangdong and Guangxi Provinces, these oceanic climate characteristics of Yunnan significantly the area also the whole China of the interplanting interplanting triple cropping of rice can increase by one season paddy rice production and results, will thoroughly solve the huge historical pressures of the grain demand of 1,300,000,000 populations.

Pass through the extensive utilization of the rice direct-seeding technology of several ten thousand mu of paddy fields for over ten years, peasants fall over each other utilization, even to surging forward the degree of falling over each other, peasants abandon the old way that ancient tradition is broadcast seedling kind paddy rice one after another, and all the direct seeding technique rice cultivation of paddy rice is used in study with open arms.Not only cost is low, income is main, and has liberated rural productivity with direct seeding technique kind paddy rice, propelled at high velocity agro-industryization, peasant's workmanization, farming workshopization, realizes agricultural modernization in advance.

Specific embodiment is as follows:

The smooth paddy field of turning over earlier is that standard is soaked in large stretch of paddy field of directly sowing sufficient base manure and agricultural chemicals in the water after 24 hours and gone with the seed rice on about four kilograms on every mu of ground then, can driedly broadcast, and with dilatory tractor-mounted drill drilling, also can the artificial broadcast.Sowing is gone up the water infiltration rice field later again, also can spray, drench filling; Also can wet and broadcast, exactly under large-area paddy field sufficient base manure and agricultural chemicals to do seedling pond Honda in the past with after image such, sheet is used for the field of long paddy rice irritates earlier and goes up water, weeds rake repeatedly again, make it level and smooth as mirror, be divided into several fritters again, be that the seed rice of standard is sowed down with about four kilograms every mu at last, later rice field field management shows identical with traditional field management, until the paddy rice of harvesting maturation.

Claims (1)

1. Chinese agriculture rice cultivation direct seeding technique has epoch-making history and realistic meaning.It is characterized in that: when rice cultivation, directly seed rice is sowed and gone growth in the large-area paddy field, no longer need to cultivate seedling in this field earlier and be transplanted to the big field of rice cultivation later on again until ripe and harvested.Can also use the direct seeding technique of this invention to carry out the interplanting interplanting double cropping rice and the triple cropping of rice, and realize agro-industryization, peasant's workmanization, realize modernization in advance, fully guarantee the grain demand of China's 1,300,000,000 populations in the vast rural area of the whole of China.
