A synchronous sowing and transplanting machine for hybrid rice seed production and a method for synchronous sowing and transplanting

Abstract

The invention relates to a synchronous seeding transplanter for hybrid rice seed production. The synchronous seeding transplanter for the hybrid rice seed production comprises a machine frame, a ditching and ridging device, a seeding device, a rice transplanting device and a power drive device, wherein the ditching and ridging device, the seeding device, the rice transplanting device and the power drive device are fixed in opposite to the machine frame. The ditching and ridging device is arranged in front of the seeding device and the rice transplanting device, and an output end of the power drive device is respectively connected with the seeding device and the rice transplanting device. The invention further relates to a synchronous seeding transplanter method for the hybrid rice seed production. The synchronous seeding transplanter for the hybrid rice seed production and the synchronous seeding transplanter method thereof have the advantages of being simple in structure and saving in energy and capable of effectively improving seed production efficiency, accurately controlling flower synchronization of male parents and female parents, and belong to the field of agriculture machinery.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a hybrid rice seed production and planting machine. Background technique [0002] Rice is the largest food crop in my country, with an annual rice planting area of ​​30 million hectares 2 About 57% of which are planted with hybrid rice. Hybrid rice is the technological achievement with the most intellectual property rights in my country. It is a major breakthrough in the history of rice breeding in the world. It has brought a leap forward to the world's rice production and achieved huge social and economic benefits. Because the good genes of hybrid rice are heterozygotes, traits will segregate in the self-bred offspring, resulting in reduced yield, so hybrid rice needs to produce seeds every year. After Yuan Longping successfully researched the technology of hybrid rice seed production, the yield of hybrid rice has been greatly improved. However, the conventional artificia...

Problems solved by technology

In addition, some domestic scientific research institutes have also carried out research on the technology of direct seeding of female parent water, but most of them still use artificial sowing or machine drill, and mainly focus on the research of agronomic technology.

[0004] So far, there is no mechanized planting and seed production method and equipment that can simultaneously complete the male parent and the female parent with the sowing period.
