How to grow rice plants

Abstract

The present application relates to a method for planting Oryza plants, which comprises the following steps: selecting a variety with strong main panicle dominance as the rice seed; sowing with the target seeding rate so that there are at least 100,000 non-tillering basic seedlings per mu; The whole growth stage controls the tillering, prevents the occurrence of tillering, and promotes the death of tillering seedlings. The above-mentioned Oryza planting method overcomes the technical prejudice of the traditional Oryza planting method, adopts an ultra-dense planting method that runs counter to hybrid rice, and keeps only the main panicle as much as possible to develop the natural main panicle. Advantages allow Oryza plants to increase production and income voluntarily and actively. On the one hand, the offspring effect of the advantage of the main ear can be used, and on the other hand, the advantage of the main ear can be used in the current season. The opposite new direction of increasing production and income of hybrid rice is an important and significant new technology.

Description

technical field [0001] The present application relates to the field of agricultural planting, in particular to a method for planting plants of the genus Oryza. Background technique [0002] The main panicle advantage of rice originally refers to the advantages of increasing yield and so on in conventional rice breeding by using the seeds of the main panicle compared with the seeds of the tiller panicle. Here, the dominance of the main panicle refers to the comparison between the main panicle and the tiller panicle in terms of progeny traits. Usually, the yield increase of the main panicle dominance relative to the tiller panicle is about 10%. Another concept of main panicle dominance comes from the comparative advantage of the main panicle and tillering panicle in contemporary yield traits. This main panicle dominance originates from the comparative difference between the rice panicle formed by seed buds and the rice panicle formed by tiller buds. Compared with the tiller p...

Problems solved by technology

[0004] That is to say, the main panicle advantage exists naturally. At present, the hybrid rice technology has developed to a certain bottleneck, and it is difficult to reflect the main panicle advantage by changing the overall balance between the main panicle and tillers.
