Abstract
The invention discloses a method for seed production of hybrid rice. The method comprises the following steps: 1) seeding, wherein the male parent is seeded in two stages; 2) raising rice seedlings: spraying the male parent in the stage I and the male parent in the stage II by using paclobutrazol, wherein the seedling age of the male parent in the stage I is controlled at 20-25 days and the seedling age of the male parent in the stage II is controlled at 16-20 days; 3) transplanting rice seedlings by way of firstly transplanting the male parent and then transplanting the female parent or firstly transplanting the female parent and then transplanting the male parent; and 4) harvesting. The method disclosed by the invention can break through the bottleneck that the seed preparing male parent for hybrid rice cannot be transplanted and harvested by machines, and a mechanized hybrid rice seed preparation method which is high in operating efficiency, simple to operate, wide in applicability and excellent in quality and high in yield is provided.
Description
Technical field
The present invention relates to agricultural plantation technology field, be specifically related to the producing method for seed of a kind of hybrid rice.
Background technology
The breeding technology for hybrid rice of China's current is the labor-intensive technology set up the eighties in 20th century, this technology recruitment is many, labour intensity is large, manage meticulous, but along with the fast development of Chinese society's economy, the problem that in production of hybrid seeds process, hired laborer is difficult, labour costs is high manifests day by day, and breeding of hybrid rice mechanization is imperative, and the mechanized cultivation of Parent, results are the important rings realizing breeding of hybrid rice mechanization.In prior art, maternal machine transplanting of rice machine is received in some areas and has been demonstrated and promoted, but the machine transplanting of rice machine of male parent receipts technology is difficult to break through always.Publication number is CN101317546A, name is called that the patent application of " utilizing the hybrid crop mechanization seeding technique of combined parent strain " proposes and utilizes the existing parent of hybrid crop or seed selection difference phase homotype system to carry out arranging in pairs or groups on the basis of acquisition combined parent strain, adopt Parent by suitable row than the mode of carrying out Mechanization sowing or transplanting seedlings, extension set harvesting Parent is carried out after ripe, synchronous alternately operating completes harvesting process, or gathers in Parent respectively with separate unit grain header simultaneously and guarantee that hybrid seed and male parent seed do not mix.In this technology, Parent must be sowed or the machine transplanting of rice same period, therefore be only suitable for the less combination of sowing gap stage, and the larger combination of sowing gap stage just cannot be applied, and point transplanting, harvesting, synchronous alternately operating, mechanical work efficiency is low, is difficult to ensure that hybrid seed and male parent seed do not mix, if separate unit grain header gathers in Parent respectively simultaneously, do not mix again, owing to also not having this grain header now, therefore this technology just a kind of imagination, is difficult to practical application aborning.
Summary of the invention
Technical problem to be solved by this invention is, overcome the shortcoming of above prior art: provide a kind of breeding of hybrid rice male parent that breaks through can not the bottleneck received of machine transplanting of rice machine, provide that a kind of operating efficiency is high, easy and simple to handle, the producing method for seed of the mechanization hybrid rice of wide adaptability, good quality and high output.
Technical solution of the present invention is as follows: the producing method for seed of a kind of hybrid rice, comprises the following steps:
1) sow male parent respectively maternal, wherein male parent divides the sowing of 2 phases, and I phase male parent and II phase male parent sow interval 3 ~ 8 days;
2) male parent female parent all uses Nutrition Soil seedling, and I phase male parent uses 150mgkg respectively in 1 leaf 1 heart stage and 2 leaf 1 heart stages
-1and 300mgkg
-1paclobutrazol solution spray seedling, II phase male parent is at 1 leaf 1 heart stage 200mgkg
-1paclobutrazol spray seedling, I male parent length of time rice seedlings grow phase controlled at 20 ~ 25 days, and II male parent length of time rice seedlings grow phase controlled at 16 ~ 20 days;
3) employing is planted maternal mode or is first planted maternal rear mode rice transplanting of planting male parent after first planting male parent, parental is 2 ︰ 8 or 2 ︰ 9, corresponding railway carriage or compartment is wide is 305cm or 330cm, 2 row male parents are inserted in every railway carriage or compartment, wherein 1 row I phase male parent, 1 row II phase male parent, male parent line width remains on 130cm, and ridge surrounding inserts 2 row II phase male parents;
The mode of planting female parent after first planting male parent is: insert kind of a male parent with riding type high-speed transplanter, and plug in rice transplanter first seedling case when planting and fill I phase male parent, the 3rd seedling case fills II phase male parent, and all the other seedling casees do not fill rice shoot, and male parent line-spacing is 50cm, reserved good maternal row in railway carriage or compartment; Kind of a female parent is inserted again with riding type high-speed transplanter;
First planting maternal rear mode of planting male parent is: first adopt riding type high-speed transplanter to insert kind of a female parent, the maternal spacing of adjacent wing-rooms on either side of a one-story house is 130cm, this spacing is as reserved male parent row, between ridge surrounding and railway carriage or compartment, also reserved spacing is the vacant as male parent row of 130cm, when male parent is inserted kind with hand-held 2 row rice transplanter in reserved male parent row rice transplanting, a seedling case of hand-held 2 row rice transplanter fills I phase male parent rice shoot, another seedling case fills II phase male parent rice shoot, male parent line-spacing is 30cm, and the line-spacing of male parent and adjacent female parent is 50cm;
4), after male parent maturation, by 2 row grain header harvesting male parents, first cut ridge surrounding male parent, then cut all the other male parents, after harvesting, pick up the male parent spike of rice being only scattered in field, then carry out female parent and gather in.
Described riding type high-speed transplanter is that foreign horse VP9D four-wheel riding type high-speed transplanter or well close PZ80D-25 riding type high-speed transplanter.
Described hand-held 2 row rice transplanter is Kubo field SPW-28C hand-held 2 row rice transplanter.
Described 2 row grain headers are Kubo field PRO208 half feed combine harvester.
Male parent is inserted male parent than hand and do sth. in advance 2 ~ 4 days sowing time sowing time.
The invention has the beneficial effects as follows:
1. can adapt to the combination of different breeding of hybrid rice.Mode reserved maternal row in railway carriage or compartment that male parent is first planted, maternal mode of first planting is reserved male parent row in railway carriage or compartment, and the Parent by stages machine transplanting of rice can not cause rice shoot to mix.
2. operating efficiency is high.By rice transplanting machine transplanting of rice kind male parent, a machine, can insert 50 ~ 60 mu in one day; Gather in male parent with grain header, a grain header can gather in 60 mu in one day.
3. save cost.The male parent machine transplanting of rice is inserted every mu than hand and is saved cost 20 yuan, and male parent machine is received and saved cost 80 yuan than manually cutting rice every mu.
4. improve male parent yield and quality.Because male parent machine receipts operating efficiency is high, relaxed contradiction in season, can ensure that male parent is gathered in the crops after maturation again, every mu can increase male parent output 25kg, and male parent paddy quality is good, can make commodity food and sell.
5. guarantee hybrid seed purity.Male parent is first gathered in, after picking up clean spike of rice, gather in female parent again, and hybrid seed can not be caused to mix.
6. hybrid seed yield is high.Male parent changes duplicate rows by original single file, correspondingly adds pollen amount, improves outcrossing seed-setting rate, and hybrid seed yield inserts the field volume increase of male parent than artificial hand, can increase production about 10%.
