Problems solved by technology

[0003] At present, the increase in yield and quality of super rice is mainly considered from the selection of high-quality varieties, the adoption of scientific cultivation methods, the provision of good field equipment, and the application of special fertilizers. It has produced significant effects, but it is difficult to further improve

Embodiment Construction

[0010] Below by embodiment, the present invention will be further described.

[0011] The experimental soil of the super rice planting experiment is the red-yellow mud developed by the Quaternary loess, with medium fertility. Before planting, the field test area was uniformly topdressed. According to the rice planting, 12-15kg of pure nitrogen was applied per mu, and the phosphorus, nitrogen, and The ratio of potassium fertilizer is 1:1:1.4, and the area of ​​each experimental field is 1.44m2. 2 , the uniform fertilization rate in the experiment is, nitrogen fertilizer: urea 25g / block, phosphate fertilizer Ca(H 2 PO 4 ) 2 , 25g / block, potassium fertilizer: KCL35g / block. The rice variety Shenyou 9586 was used in the experiment.

[0012] First dig trenches side by side in the test field, and bury PVC plastic hoses with a diameter of about 5 mm side by side. One end of the PVC plastic hoses is uniformly sealed with iron wires, and 2 holes are tied with iron wires every 10 cm,...

Abstract

The invention discloses a super rice oxygen aeration irrigation method. The super rice oxygen aeration irrigation method comprises the following steps: carrying out oxygen aeration in the daytime of a tillering period, carrying out oxygen aeration at night in a heading period and carrying out oxygen aeration in the daytime of mature period. By virtue of the super rice oxygen aeration irrigation method, the increase of species and quantities of microorganisms in the rhizosphere soil of the super rice can be facilitated; and the rice yield can be remarkably improved.

Description

technical field [0001] The invention relates to a crop irrigation method, in particular to an oxygen-increased irrigation method for super rice. Background technique [0002] Super rice, that is, rice super-high-yielding varieties, has been a key research project of many countries and research institutions in recent decades under the background of increasing pressure on food security at home and abroad. In Japan, some scientists began research on super-high-yield rice breeding in the early 1980s, with the aim of increasing the yield of rice by 50% per mu within 10 to 15 years. In the late 1980s, the International Rice Research Institute also launched a breeding program for "super rice", aiming to increase the yield per mu of rice varieties cultivated in the early 21st century by 20% to 25% compared with the highest existing varieties. No big breakthrough yet. my country only started its own super rice breeding program in the mid-1990s. After more than ten years of scientif...
