Description

A kind of wheat head progeny row seeder for crop field experiment

Technical field

The utility model relates to agricultural machinery technological field, specially a kind of wheat head progeny row for crop field experiment is broadcast Kind machine.

Background technique

Head progeny row breeding experiment is that cereal, beans new varieties enter the important link before area's examination and kind detection, seeding quality Directly affect the accuracy of crop head progeny row comparative test.It is relatively flourishing since the research of China's breeding mechanical equipment is started late For country, the breeding Mechanization Level in China still more falls behind, and 80% or more breeding production equipment needs external introduce.It is external Field stock breeding machinery is expensive, and adequate and systematic service is relatively deficient in the specialized maintenance improvement personnel of China's field machinery, purchase The machinery bought can not be merged organically during actual job with local work pattern.Therefore, a kind of suitable China is researched and developed The head progeny row seeder of cropping pattern and agriculture requirement improves wheat yield for exploitation high yield, stable yields, good wheat breeding, The international competitiveness for promoting the grains germplasm such as China's wheat has great significance.

The requirement of head progeny row seeder is: to prevent variet complexity, need to uniformly finish in defined cell length a certain amount of Seed, interval walking a distance after sow next cell again, the gap length between cell and cell must control standard Really.Domestic traditional head progeny row seeder does not have automatic seed-feeding device and in the ranks synchronizes automatic control seed-dropping equipment, due to planning cell Gap length is shorter, it is therefore desirable to and it shuts down before each cell is sowed and is manually charged seed, cause minizone operation discontinuous, then By the every row planting of manual control, the more difficult synchronization of planting in the ranks causes cell sowing row length irregular, the control of cell gap length Not precisely, breeding precision is influenced.External more advanced head progeny row seeder has been provided with automatic seed-feeding device and synchronous control planting in the ranks Device, but automatic seed-feeding device needs artificial triggering with the action signal of synchronous automatic control seed-dropping equipment in the ranks, that is, needs before working It is for kind of device and same in the ranks by manually pressing control button when reaching each cell sowing label in each cell setting flag Step control seed-dropping equipment can auto-action.Due to the generally existing error of manual control, cause the control of cell gap length not smart Standard influences to test precision.

In order to ensure the purity and production performance of wheat breeding, present wheat breeding cell generally uses head progeny row method of purification raw Produce head progeny row original seed.State Council, the Central Committee of the Communist Party of China in 2016 points out in " No.1 Central File " of publication, " it is great to push forward breeding comprehensively Scientific research research cooperation is cultivated and is promoted adapting to mechanization production, high yield and good quality extensively suitable new varieties, accelerates staple food crop New round Cultivar replacing is regenerated ".
