Rice breeding method for observing rice yield through pollination time

Abstract

The invention discloses a rice breeding method for observing rice yield through pollination time. The rice breeding method comprises the following steps that 1, plump rice seeds uniform in size are selected, and the seeds are evenly placed in a 300-fold trichloroisocyanuric acid soaking solution to be soaked for 48-52 h; 5, the seeds with metalaxyl-M on the surfaces are sown in soil for seedling breeding; 6, rice seedlings are transplanted, and during transplanting, tall and straight rice seedlings are selected and transplanted in four parts, wherein two parts are subjected to pollination through natural growth, and the other two parts are subjected to artificial pollination; after pollination is completed, one of the natural growth pollination parts and one of the artificial pollination parts are watered. By means of the rice breeding method for observing rice yield through pollination time, the relationship between the rice yield and the pollination time and the problem whether pollen falling influences the rice yield or not can be observed.

Description

technical field [0001] The invention relates to the technical field of rice planting, in particular to a rice breeding method for observing rice yield through pollination time. Background technique [0002] Rice belongs to cereals. Rice is rice after husking. Nearly 50% of the world's people have rice as their staple food. In my country, 65% of the regions use rice as their staple food. Therefore, stable and high-yield rice has always been a concern of people. In order to obtain stable and high-yield rice, people have been selecting and breeding rice to obtain rice with higher yield. [0003] At present, there are still deficiencies in the use of rice breeding methods, and it is impossible to judge whether the pollen pollination time affects the rice production in the later stage, and whether the shedding of pollen after pollination affects the rice production in the later stage. A rice breeding method for rice yield to solve the problems raised by the above-mentioned backgr...
