An amphibious mobile seed production device and its working method

Abstract

The invention relates to a device for preventing different kinds of pollens from contamination during the process of the small-area seed production of hybrid rice, and provides an amphibious movable seed production device and an operating method thereof. The device comprises a main body adopting a boat-shaped structure; soil is filled at the bottom of the main body; the main body is provided with a drain device; the drain device is arranged below the surface soil; and the main body is provided with an iron pull ring used for being dragged. The device can not only solve the problem of contamination during the development and seed production processes of the hybrid rice, and relieve the pressure of shortage of land and manpower resources, but also achieve the parental multiple matching of the rice, thereby saving manpower and material resources, and improving the breeding, development and seed production efficiency of the rice.

Description

technical field [0001] The invention relates to a device for preventing pollen of different varieties from being pollinated during the small-area seed production process of hybrid rice, in particular to an amphibious mobile seed production device and a working method thereof. Background technique [0002] In the research and development and production of hybrid rice breeding, the link of preventing pollination is very important. my country is the birthplace of hybrid rice, and the successful development of hybrid rice has made outstanding contributions to solving the world's food security problems. The R&D and production process of hybrid rice mainly includes germplasm innovation, testing and matching of new varieties (combinations), trial production of new varieties (combinations), pilot demonstration of new varieties (combinations), seed production, seedling raising, transplanting, field management, harvesting, etc. . New variety (combination) testing, trial production, ...

Problems solved by technology

For this reason, rice breeding scientific research bases usually use methods such as erecting plastic sheets and cotton cloths to manually set up isolation, but this method is time-consuming, labor-intensive, and requires a lot of investment, and repeated construction is required every year. The distance of pollination is very long, and it is easily affected by strong winds. The isolation effect of this method cannot be guaranteed.

For this reason, when many domestic rice scientific research units apply for new varieties (combinations) to participate in regional tests at all levels, they often cause the test results to be discarded due to the seed purity not meeting the standard due to pollination, which greatly affects the output of scientific research results.
