Night mechanical aerobic irrigation method for super rice

Abstract

The invention discloses a night mechanical aerobic irrigation method for super rice. In the whole growth period of super rice, air is added to rhizosphere soil of the rice at night. According to the method, the population diversity of rhizosphere microorganisms of the soil is prompted in the heading period, and the yield of the rice is remarkably increased.

Description

technical field [0001] The invention relates to a crop irrigation method, in particular to a nighttime mechanical aeration 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...

AI Technical Summary

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
