Field row proportion setting method for whole mechanized hybrid rice seed production

Abstract

The invention belongs to the technical field of agricultural seed production, and particularly relates to a field row proportion setting method for whole mechanized hybrid rice seed production. The method includes the steps of (1) using a tillage machine to level a seeding field; (2) planting male parents and female parents by using a rice direct seeding machine or a rice transplanter in a male parent-female parent ratio of 2m: 4m, 10-12 rows: 20-24 rows; (3) using unmanned helicopters for auxiliary pollination and pesticides or hormones spraying; and (4) using rice harvesters to harvest the male parents and female parents. Mechanical transplanting and mechanical harvesting of male parents are realized through the method, which breaks through the technical bottleneck of mechanization of the whole process of seed production. The mechanization of the whole production process reduces the labor cost, the limitation of labor factors is effectively overcome, the large-scale seed production is promoted, and the supply of improved seeds is ensured. The male parent transplanting is changed to machine planting and harvesting. Although the number of male parent rows are increased and the rowratio is reduced, the amount of pollen and self seed set rate are improved. The benefit of reduced effective seed production due to increased male parents is lower than the benefit of labor cost saved by applying mechanization.

Description

technical field [0001] The invention belongs to the technical field of agricultural seed production, and in particular relates to a field row ratio setting method for full mechanized hybrid rice seed production. Background technique [0002] In the traditional rice seed production process, the male parent is mostly planted in single or double rows in the female parent, and can only be transplanted and harvested manually, which increases production costs and reduces work efficiency. With the large-scale transfer of land and rural areas With the massive transfer of labor force to the secondary and tertiary industries, the contradiction of relying on manual operation for hybrid rice seed production has become more prominent. The way to solve it must develop large-scale mechanical seed production. Contents of the invention [0003] Aiming at the above technical problems, the present invention proposes a field row ratio setting method for fully mechanized hybrid rice seed prod...
