Embodiment 1

[0016] A new method for hybrid rice seed production, the specific method steps are as follows,

[0017] 1. According to the reproductive characteristics of the parents, re-determine the sowing period of the parents, and cannot copy the traditional artificial planting mode or the sowing period of the parents of the female parent live broadcast, so as to ensure that the flowering period of the parents of the combination meets;

[0018] 2. The double-machine transplanting technology of the parents, the premise is that the seedlings of the parents adopt floppy disks for seedling cultivation. There are two parts, one part is the tray, the other part is the floppy disk where Yagu is implanted. There are several leak holes at the bottom of the floppy disk, which can not only leak water, but also absorb water on the seedbed. The tray and floppy disk are both plastic products and can be reused. The specification is 30cm*60cm. During operation, the floppy disk is placed in the tray, and...

Abstract

The invention relates to a new method for hybrid rice seed production, belonging to the technical field of agriculture. According to the method, a double-machine transplanting technology is adopted for changing the traditional manual transplanting mode and also changing the adverse situation of easy lodging due to direct seeding. The method can be suitable for hybrid rice seed production for any combination, lodging-resistant or non-lodging-resistant varieties and high-straw or short-straw rice, so that the method has a wide prospect in the field of seed production.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a new method for hybrid rice seed production. Background technique [0002] As we all know, hybrid rice seed production is a high-tech, labor-intensive, costly, and risky agricultural system engineering. With the large transfer of rural population to cities in recent years, hybrid rice seed production is difficult, expensive, and costly contradictions are becoming increasingly prominent. In order to reduce costs and improve the economic benefits of seed production, the applicant, through research on seed production technology and repeated scrutiny in 2011, decided to implement a new method of male-based machine transplanting and female-based machine transplanting in an area of ​​more than 800 mu in the Baihu seed production base of Chaohu Lake. The technical measures (hereinafter referred to as the double-machine transplanting technology) have achieved success. The yield o...
