Abstract

The invention belongs to agriculture seeding technique fields, and in particular to a kind of field row of entire mechanization breeding of hybrid rice uses the smooth seed farm of ploughing machine than setting method, (1)；(2) using paddy planter or rice transplanter plantation male parent and female parent, parental 2m:4m, 10-12 row: 20-24 row；(3) supple-mentary pollination and spraying pesticide or hormone are carried out using unmanned helicopter；(4) male parent and female parent are gathered in using rice harvester respectively.Male parent of the present invention realizes machine rice transplantation and mechanical harvesting, breaches the technical bottleneck of production of hybrid seeds entire mechanization.By the entire mechanization of production process, labour costs is reduced, the limitation of labour's factor is effectively overcome, promotes scale production of hybrid seeds production, it is ensured that the supply of breeding；Male parent, which is planted, simultaneously is changed to machine transplanting of rice machine receipts, although male parent line number increases row than reducing, increases pollen amount, improves outcrossing seed-setting rate.Germinative seed output is lower than the benefit for applying mechanization to save labor cost because male parent increases reduced benefit.

Description

The field row of entire mechanization breeding of hybrid rice compares setting method

Technical field

The invention belongs to agriculture seeding technique fields, and in particular to a kind of field row of entire mechanization breeding of hybrid rice Compare setting method.

Background technique

During traditional rice production of hybrid seeds, male parent mostly uses greatly uniline or duplicate rows to be planted in female parent, and can only people Work rice transplanting and harvesting, increase production cost, reduce working efficiency, with soil it is extensive circulation and rural laborer to A large amount of transfers of second and third industry, breeding of hybrid rice rely on the more aobvious protrusion of manually-operated contradiction.Its approach solved, gesture The scale machinery production of hybrid seeds must be opened up.

Summary of the invention

In view of the above technical problems, the invention proposes a kind of field rows of entire mechanization breeding of hybrid rice than being arranged Method establishes Parent production of hybrid seeds mechanization and educates rice transplanting technology, forms hybrid rice entire mechanization seeding technique system.It can Good operability, applicability is wide, and economic and social profit is significant, anxious to current breeding of hybrid rice lack of labor, cost is solved The problem of play improves pushes hybrid rice development to be of great significance, is the great innovation of breeding technology for hybrid rice.

Specific technical solution are as follows:

The field row of entire mechanization breeding of hybrid rice is than setting method, including following procedure:

(1) the smooth seed farm of ploughing machine is used；

(2) using paddy planter or rice transplanter plantation male parent and female parent, parental 2m:4m, 10-12 row: 20-24 Row；

(3) supple-mentary pollination and spraying pesticide or hormone are carried out using unmanned helicopter；

(4) male parent and female parent are gathered in using rice harvester respectively.

The field row of entire mechanization breeding of hybrid rice provided by the invention is than setting method, bring beneficial effect Have: male parent realizes machine rice transplantation and mechanical harvesting, breaches the technical bottleneck of production of hybrid seeds entire mechanization.Pass through the complete of production process Journey mechanization, reduces labour costs, alleviates labor intensity, effectively overcomes the limitation of labour's factor, promote scale Production of hybrid seeds production, it is ensured that the supply of breeding；Male parent, which is planted, simultaneously is changed to machine transplanting of rice machine receipts, although male parent line number increases row, ratio reduces, Pollen amount is increased, outcrossing seed-setting rate is improved.Germinative seed output is lower than application machinery because male parent increases reduced benefit Change the benefit for saving labor cost.

Specific embodiment

It is described in conjunction with the embodiments the specific technical solution of the present invention.

The field row of entire mechanization breeding of hybrid rice is than setting method, including following procedure:

(1) the smooth seed farm of ploughing machine is used；

(2) using paddy planter or rice transplanter plantation male parent and female parent, parental 2m:4m, 10-12 row: 20-24 Row,

(3) supple-mentary pollination and spraying pesticide or hormone are carried out using unmanned helicopter；

(4) male parent and female parent are gathered in using rice harvester respectively.

The hybrid rice seeds of harvesting are dried using grain drying machine.Seed production purity and production cost are better than people Work sowing harvesting.

Claims (1)

1. the field row of entire mechanization breeding of hybrid rice compares setting method, which is characterized in that including following procedure:

(1) the smooth seed farm of ploughing machine is used；

(2) using paddy planter or rice transplanter plantation male parent and female parent, parental 2m:4m, 10-12 row: 20-24 row；

(3) supple-mentary pollination and spraying pesticide or hormone are carried out using unmanned helicopter；

(4) male parent and female parent are gathered in using rice harvester respectively.
