Irrigation paddy field 'wheat culture type' rice high yield wet land seeding method

Abstract

Rice is the main crop in china, and the rice growing is the first farming. However, with the water consumption accounting for a half of national freshwater resource, the rice is the first water consumer, and the water utilization ratio is low. The phenomenon is described as one kilo of grain requiring one ton of water. Since the 1970s, the rice growing has been a typical example of agricultural non-point source pollution because of high production pursuance, and luxurious and random application of fertilizers and pesticides. For the food and etiological security, the rice growing must be reformed. With the reform of rice growing technology as a target, an ''irrigation paddy 'wheat planting type' high rice production wet planting method'' is invented. The invention comprises: (1) a soil fertility biological repair technology which integrates the soil utilization with the maintenance of soil fertility, with the paddy fertilization and crop rotation as the basis, (2) a direct sowing technology with seeding keeping, weeding and falling prevention technology as the basis, and (3) a novel water-saving rice growing irrigating system, that is, seeding in the wet soil, cultivating the root in a dry tube, developing ear in the ditch water and preventing the weakness in the dry and the wet environment, with physiological water requirement of the rice as the basis. The invention has the specific effects of saving the cost by 10 percent, saving the water by 40 percent, and achieving the stable production of 500Kg / mu, and has other ecological benefits.

Description

technical field [0001] The invention relates to a rice cultivation technique. It specifically involves a rice planting method similar to wheat farming. Compared with the traditional rice cultivation technology popularized today, which is mainly characterized by flood irrigation, seedling cultivation and transplanting, this is a new water-saving, cost-saving, environmentally friendly and stable-yield rice cultivation method. . Background technique [0002] Rice is the main food crop in my country. Rice is the staple food of 60% of the population in China, and about 50% of the farmers are engaged in rice production. Rice farming is the number one agricultural task in my country. More people, less land and less water is the basic national condition of our country. How to use limited land resources and fresh water resources to ensure food security in our country is the main proposition of the progress of rice farming science and technology. [0003] The researchers of the pres...

Problems solved by technology

Coupled with engineering and non-engineering losses, the production efficiency per ton of water is very low, only 0.6-0.8 kg / m 3 , which is equivalent to "tons of water and catties of grain"

[0007] 2. The second disadvantage of today's rice farming technology: high input of chemical fertilizers and pesticides

[0010] 3. The third disadvantage of today's rice farming technology: high pollution to the environment

First, rice paddies are the greenhouse gas CH 4 with N 2 The main release source of O; second, excess agrochemicals remain in the soil, threatening the quality and safety of rice, and destroying soil agricultural productivity; third, polluting surrounding waters, causing water eutrophication; fourth, cyclical impacts, deteriorating the ecology of rice producing areas Environmental Quality
