Description
Technical field
The present invention relates to the producing method for seed of a kind of soybean.
Background technology
Soybean is the main source of human protein's nutrition.In recent years, 150 kilograms/mu of soybean world per unit area yields, China's per unit area yield has only about 120 kg/mu, and per unit area yield is starkly lower than world average level.Under the national conditions of having a large population and a few land at present, particularly along with the increase of population and the raising of living standards of the people, demand to soybean prod is more and more powerful, it is unpractical that simple dependence enlarged-area increases the soybean gross yield, and the new technology that must seek such as heterosis utilization improves soybean yields.Hybrid vigour is one of important channel of improving the crop yield prediction level, China paddy rice, corn are extensive use of crossbreed, made per unit area yield increase sharply 1-2 doubly, the volume increase speed of the hybrid maize of nearly more than the 20 years China's hybrid rices and the U.S., adopted the volume increase speed of conventional variety before more than 20 years, the breeding hybridized grain yield genetic progress of this explanation is bigger than conventional variety; Soybean heterosis is strong, and yield potential is big, and can solve tatoin self fixed nitrogen effectively increase production unconspicuous drawback under high fertilizer and water condition; Therefore, explore the hybrid soybean seeding technique, improve hybrid seed yield, quicken hybrid soybean and be used for producing, meaning is very great.
Soybean male is sterile to be proposed by Brim and Young (1971) the earliest; The research of soybean heterosis was just set about by the U.S. since 1975, the patent disclosure of 6 hybrid soybean seeds was just arranged from 1975 to 1996, and all because of immature in theory, operability is not strong, and can't implement for these patents, at present still low-level.China starts late in the research of soybean heterosis aspect utilizing, but makes much progress.Yu Jianzhang (1996) has applied for a patent of utilizing caryon sterile line to produce hybrid soybean seeds, because maternal row can only be isolated 1/4th sterile strain, the hybrid pick-up rate is too low, and can not remove before blooming and can educate strain, the soybean false hybrid easily takes place, and is difficult for utilizing; The academy of agricultural sciences, Jilin Province takes to this respect research from nineteen eighty-three, obtained the soya cells matter male sterile line and the homotype maintenance line of the cultivated soybean and wild soybean hybridization in 1993, realized that subsequently " three are " is supporting, and bred the first in the world hybridization spring soybean kind in 2002; The academy of agricultural sciences, Anhui Province has realized that soybean M type male sterility three line is supporting by 10 years of researches, has bred in the world first hybridization summer soybean varieties that can be directly used in production No. 1, assorted excellent beans " (Anhui beans 25) " in October, 2004; Agricultural University Of Nanjing bred cytoplasmic male sterile line and maintenance line in 1998; It is highly sterile that F1 also appears in 2 combinations of the Fuyang city institute of agricultural sciences (1995) report, the normal phenomenon of reciprocal cross fertility, and they think the genus cytoplasmic-nuclear male sterility, realize also that at present " three are " is supporting.The summer soybean crossbreed that spring soybean crossbreed that Jilin Province breeds the academy of agricultural sciences and academy of agricultural sciences, Anhui Province breed significantly is better than conventional soybean at aspects such as resistance, lodging resistance and yielding abilities, and to improving the soybean per unit area yield, the development soybean produces and is of great importance.
Though, the seed selection of hybrid soybean kind is in the ascendant, being limited to soybean is strict self pollination crop, natural outcrossing rate is low, utilize the wind pollination difficulty big, increased many difficulties for the production of hybrid seeds of hybrid soybean, have not yet to see simple and easy, a soybean cross-breeding technology efficiently, it has become the restriction hybrid soybean and has been directly used in the bottleneck that the land for growing field crops produces.
Summary of the invention

Concrete sowing operation may further comprise the steps:
A, set up isolated area: the seed farm circumference must not be planted other soybean varieties for 200 meters, and the male parent kind should be planted in the protection zone around the seed farm, pulls out different strain according to proterties such as soybean varieties pattern, fine hair look, the ripe look of pod and pod bearing habits, the raising seed production purity.
B, row are to selection: thing capable to.In the Northwest that China's west wind blows hard, thing in the ranks air-flow connects, and is dry nice and cool, help insect flying, and the flower beanpod in the strain can be avoided the sunlight of south direct projection, is beneficial to guarantor's flower and protects pod.
C, date of seeding: male sterile line (female parent) early sowing, adopt the mode of wheat cover beans or select precocious big wheat stubble for use, sow in 15-25 day in May, because male sterile line derives from the Yellow River and Huai He River southern areas, postpone flowering stage in the Northwest's production of hybrid seeds, early sowing in good time makes soybean can bloom in the 15-20 day high temperature and little rainfall time in July in advance in production of hybrid seeds base, maintenance line or recover system's (male parent) and determine suitable sowing date with maternal flower synchronization according to the morning and evening at kind self florescence; Maintenance line or recovery system in the male sterile line planted on two sides adopt the interval to sow in 10-15 days by stages, effectively prolong the pollen supply of male parent.
D, narrow wide row plantation: narrow wide row is plantation alternately; Be narrow row line-spacing 40cm, wide every trade is apart from 60cm.The narrow row closing, be convenient to glimmering chrysomelid cover to perch with the flower thrips short distance pollinate; Spacious between wide capable strain, be convenient to shuttle flights pollination such as yellow wild bee, black wild bee, white butterfly, also be beneficial to aeration-cooling and flowering, pollen bulk storage.
E, thin planting: at medium rich water field piece, density is 10000-12000 strain/mu, fertilizer and water condition preferably field piece density be 8000-10000 strain/mu; The field envelope is controlled at the whole florescence on the departure date, is convenient to the pollination of circling in the air of honeybee, butterfly, glimmering insect such as chrysomelid.
F, father and mother's one's own profession ratio: male parent: female parent is 1: 2 row ratio configuration.
G, florescence pour water in good time: initial bloom stage keeps soil moisture content 40-60%, guarantees that abundant bulk storage of pollen and insect actively pollinate, but to the whole florescence be lower than at 70% o'clock as the signs of drought or field capacity occurring, in time pour water, protect flower and protect pod, improve hybrid seed yield.
The prevention and elimination of disease and pests of use highly toxic pesticide is prohibited in field damage by disease and insect prevention and control, duration of flowering, in order to avoid accidentally injure insect pollinator.Therefore before blooming, should conscientiously carry out the disease insect protected work of looking into, based on efficient physical (as light trap) technology prevention damage by disease and insect.
Producing method for seed of the present invention can effectively improve hybrid seed yield 20-30%.
