Embodiment 1

[0030] In 2014, a cultivation technique experiment was carried out at the Fuyang base of the China Rice Research Institute to prevent lodging of high-yield rice by increasing oxygen in the root system and strengthening the stalks to prevent falling. Conventional japonica rice was sown on May 20 and transplanted on June 16. The plant spacing × row spacing = 20cm × 25cm, Insert 3 to 4 copies in each hole, complete the ear on September 2, and harvest on November 15. The area of ​​each plot in the test is 20m 2 , each treatment was repeated 5 times, and each plot was randomly arranged. The field water and fertilizer management of the treatment is carried out according to the technology of the present invention, and the contrast is traditional deep water irrigation. The control of diseases, insect pests and weeds and fertilizer management are the same as conventional field production. The experimental plots are randomly arranged, and the yield of each plot obtained by harvesting a...

Embodiment 2

[0035] In 2015, in the Fuyang base of the China Rice Research Institute, a cultivation technique experiment was carried out to prevent lodging of high-yielding rice by increasing oxygen in the roots and strengthening stalks. The rice variety used for the test: Zhongzheyou No. 1 (hybrid rice), which is more prone to lodging under the condition of high N fertilizer , bred by the China Rice Research Institute. The test materials were sown on May 20, 2015, and transplanted on June 16, with a single plant in each hole. Plant spacing×row spacing=20cm×30cm. The field water and fertilizer management of the treatment is carried out according to the technology of the present invention, and the contrast is traditional deep water irrigation. The control of diseases, insect pests and weeds is the same as conventional field production. The test plots are randomly arranged, and the yield of each plot obtained by harvesting and yield measurement is shown in Table 2 below: harvested on Octobe...

Abstract

The application discloses a high-yield cultivation method for rice by increasing oxygen in the root system, strengthening the stalks and preventing lodging. The method comprises the following steps: cultivating multi-tiller and strong seedlings, transplanting the seedlings in good time, digging deep drainage ditches for high-yield, and creating an oxygen-enriched root-strengthening soil environment for irrigation , Pest control and weed control are the same as conventional field production. This method excavates deep ditches in rice fields, and at different stages of rice growth, by implementing technical measures to control or reduce or empty the ditch water in paddy fields, the soil oxygen environment in paddy fields is improved and the oxygen nutrition of rice roots is increased, so as to realize strong root prevention of rice. Lodging and high yield.

Description

technical field [0001] The application belongs to the field of plant cultivation, and in particular relates to a high-yield cultivation method for rice by increasing oxygen in the root system, strengthening the stalks and preventing lodging. 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] In the last century, the research and utilization of rice dwarf gene and sterile gene were successful, and the advancement of rice farming technology centered on the promotion of rice dwarf varieties and hybrid rice, ...
