Hybrid rice senility-resistant grain-plumping lodging-resistant high-yield culture technology

Abstract

The invention discloses a hybrid rice senility-resistant grain-plumping lodging-resistant high-yield culture technology, and belongs to the technical field of super hybrid rice planting. Existing super hybrid rice has the defects of premature senility, lodging and the like. According to the method, in a rice field, early season rice cultivars are cultured in a disalignment mode with the density being 5*(5+10) inch, the late rice cultivars are cultured in a disalignment mode with the density being 6*(5+10) inch, and the single-season semilate rice cultivars are cultured in a disalignment mode with the density being 6*(8+10) inch. The early season rice cultivars, the late rice cultivars and the single-season semilate rice cultivars are cultured in a disalignment mode with different densities, so that senility resistance and grain plumping are facilitated, and the setting rate and the yield are improved. Accordingly, rice senility, lodging and the other phenomena can be avoided, and the high social and economic benefits are provided for agricultural technology progress and rice cultivation in China.

Description

technical field [0001] The invention belongs to the technical field of super hybrid rice planting, and in particular relates to a hybrid rice anti-aging and strong seed anti-lodging and high-yield cultivation technology. Background technique [0002] Super hybrid rice is the technical achievement of super hybrid rice proposed by Academician Yuan Longping. It uses 3 mu of land to produce 4 mu of grain. The economic benefit of growing grain ensures national food security. On October 5, 2014, the acceptance expert group announced the scientific research results to the outside world at the Agricultural Bureau of Longshan County, Hunan Province. The yield per mu is 1004.5 kg. On the 5th, the acceptance expert group announced the scientific research results to the outside world at the County Agricultural Bureau. The successful large-scale demonstration means that it can be planted on a large scale in a large area and in a wide range in ASEAN countries, and high-quality and high...

Problems solved by technology

However, a large amount of fertilizer input, on the one hand, leads to excessive fertilizer absorption by rice, which aggravates the negative effects of pest damage, rice overgreening and late maturity, and lodging and yield reduction. On the other hand, it also affects the benefits of rice production.

However, due to the high yield of super hybrid rice, it is because of its large biomass and high harvest index; but there are also hidden dangers: such as premature aging (variety problems, cultivation techniques), lodging, etc.
