Description
Technical field
The present invention relates to agricultural plantation technology field, and in particular to a kind of producing method for seed of hybrid rice.
Background technology
The breeding technology for hybrid rice of China's current is the labor-intensive technology set up 1980s, the skill
Art recruitment is more, and labor intensity is big, and management is fine, but with the fast development of Chinese society's economy, hired laborer's hardly possible, labor during the production of hybrid seeds
The problem of power cost is high increasingly shows, and breeding of hybrid rice mechanization is imperative, and the mechanized cultivation of Parent, harvest are
Realize an important ring for breeding of hybrid rice mechanization.In the prior art, maternal machine transplanting of rice machine is received in some areas and demonstrated
And popularization, but male parent machine transplanting of rice machine receive technology be difficult to break through always.Publication No. CN101317546A, entitled " utilization combination
The patent application of the hybrid crop mechanization seeding technique of parent " proposes same using the existing parent of hybrid crop or seed selection poor phase
Type system is carried out on the basis of collocation obtains combined parent strain, using Parent by appropriate row than carrying out Mechanization sowing or transplanting seedlings
Mode, it is ripe after carry out extension set harvesting Parent, synchronous alternately operating completes harvesting process, or with the separate unit harvester same time-division
Parent and it Shou Ge not ensure that hybrid seed does not mix with male parent seed.Parent must same period sowing or machine in this technology
Insert, therefore be only suitable in the less combination of sowing gap stage, and the larger combination of sowing gap stage can not just be applied, and extension set rice transplanting, receipts
Cut, synchronous alternately operating, mechanical work efficiency is low, it is difficult to ensure that hybrid seed does not mix with male parent seed, if separate unit is received
Cutting mill gathers in Parent respectively simultaneously, and does not mix, and due to currently there are no this harvester, therefore this technology is one kind
Contemplate, it is difficult to practical application in production.
The content of the invention
The technical problems to be solved by the invention are the shortcomings for overcoming above prior art：A kind of break through is provided and hybridizes water
Rice production of hybrid seeds male parent be unable to the bottlenecks of machine transplanting of rice machine receipts there is provided a kind of operating efficiency is high, easy to operate, wide adaptability, good quality and high output
The producing method for seed of mechanization hybrid rice.
The technical solution of the present invention is as follows：A kind of producing method for seed of hybrid rice, comprises the following steps：
1）Sowing male parent is maternal respectively, wherein the sowing of 2 phases of male parent point, I phase male parent and II phase male parent sowing interval 3~8
My god；
2）Male parent female parent uses Nutrition Soil seedling, and I phase male parent is in the heart stage of 1 leaf 1 and the heart stage of 2 leaf 1 respectively with 150 mg kg-1
With 300 mg kg-1Paclobutrazol solution sprays seedling, and II phase male parent is in the heart stage of 1 leaf 1 with 200 mg kg-1Paclobutrazol sprays seedling, I phase male parent
Length of time rice seedlings grow control was at 20~25 days, and II male parent length of time rice seedlings grow phase was controlled at 16~20 days；
3）The mode rice transplanting that male parent is planted after female parent is planted by the way of female parent is planted after first cultivation male parent or first, parental is
2 ︰ 8 or 2 ︰ 9, correspondence railway carriage or compartment a width of 305cm or 330cm, 2 row male parents are inserted per railway carriage or compartment, wherein I phase of 1 row male parent, II phase of 1 row male parent, male parent
Line width is maintained at 130cm, and ridge surrounding inserts II phase of 2 row male parent；
First planting maternal mode after cultivation male parent is：Kind of a male parent is inserted with riding type high-speed transplanter, rice transplanter first when planting is inserted
Individual seedling case fills I phase male parent, and the 3rd seedling case fills II phase male parent, and remaining seedling case does not fill rice shoot, and male parent line-spacing is 50cm, pre- in railway carriage or compartment
Stay maternal row；Again kind of a female parent is inserted with riding type high-speed transplanter；
The mode of cultivation male parent is after first cultivation is maternal：Kind of maternal a, mother for adjacent wing-rooms on either side of a one-story house is first inserted using riding type high-speed transplanter
This spacing is 130cm, and it is the vacant of 130cm that the spacing also reserves spacing as reserved male parent row, between ridge surrounding and railway carriage or compartment
As male parent row, male parent is inserted when planting with the row rice transplanter of hand-held 2 in reserved male parent row rice transplanting, the one of the row rice transplanter of hand-held 2
Individual seedling case fills I phase male parent rice shoot, and another seedling case fills II phase male parent rice shoot, and male parent line-spacing is 30cm, male parent with it is adjacent maternal
Line-spacing is 50cm；
4）After male parent is ripe, male parent is gathered in 2 row harvesters, ridge surrounding male parent is first cut, then cuts remaining male parent, gathered in
The net male parent spike of rice for being scattered in field is picked up after finishing, maternal harvesting is then carried out.
The riding type high-speed transplanter is that foreign horse VP9D four-wheel riding type high-speed transplanters or well close PZ80D-25 seatings
Formula high-speed transplanter.
The row rice transplanter of hand-held 2 is the row rice transplanter of Kubo field SPW-28C hand-helds 2.
The 2 row harvester is Kubo field PRO208 half feed combine harvesters.
Male parent sowing time inserts male parent sowing time than hand and does sth. in advance 2~4 days.
The beneficial effects of the invention are as follows：
1. adapt to different breeding of hybrid rice combinations.The mode that male parent is first planted reserves female parent row in railway carriage or compartment, and female parent is first planted
Mode reserve male parent row in railway carriage or compartment, the machine transplanting of rice does not result in rice shoot and mixed Parent by stages.
2. operating efficiency is high.With rice transplanting machine transplanting of rice kind male parent, a machine can insert 50~60 mu in one day；Gathered in harvester
Male parent a, harvester can gather in 60 mu in one day.
3. save cost.The male parent machine transplanting of rice inserts every mu of 20 yuan of cost of saving than hand, and male parent machine is received cuts every mu of saving of rice than artificial
80 yuan of cost.
4. improve male parent yield and quality.Because male parent machine is incorporated as industry efficiency high, season contradiction is relaxed, male parent is can guarantee that
Harvested again after maturation, every mu can increase male parent yield 25kg, and male parent paddy quality is good, can make commodity food sale.
5. ensure hybrid seed purity.Male parent is first gathered in, and is gathered in female parent again after net spike of rice is picked up, is not resulted in hybrid seed
Mix.
6. hybrid seed yield is high.Male parent changes duplicate rows by original single file, accordingly adds pollen amount, improves outcrossing
Rate, hybrid seed yield increases production than the field that artificial hand inserts male parent, can increase production 10% or so.
