Abstract
The invention discloses the hybrid rice seed breeding process of a kind of entire mechanization, comprise the steps: S1, select the hybrid rice that Parent duration from seeding to heading is close, brown shell marker gene is imported male parent or female parent；S2, by the Parent of hybrid rice according to seed weight than 1: 5～1: 4 mixing, carry out floppy disk seedling, rice transplanting according to the standard of transplanting；S3, heading flowering period spray hormone GA and release maternal phimosis；S4, utilizing aircraft to catch up with powder, pollination sprays Bentazon herbicide and removes most male parent；S5, carry out mechanized harvest, utilize separator the male parent of residual to be removed before warehouse-in, it is thus achieved that highly purified hybrid rice seeds.The present invention can carry out mass mechanized production hybrid rice on big farming household, large-scale farm, eliminates the reliance on intensive labour force；Simplify production of hybrid seeds program, save breeding cost, adapted to the policy of the novel farmer of national cultivation.
Description
Technical field
The present invention relates to crop breeding field, be specifically related to the hybrid rice seed breeding process of a kind of entire mechanization.
Background technology
The hybrid rice routine production of hybrid seeds, uses 2 row male parents, the pattern of 12 row female parent point railway carriage or compartment plantations, and operator's Parent is respectively
Seedling, the most first plants 2 row male parents, and after a period of time, (time span is identical with the sowing gap stage of Parent) is again every 2
Plant 12 row between row male parent maternal, after maternal pollination, cut off male parent, finally gather in the crops cenospecies.Conventional producing method for seed program is multiple
Miscellaneous, recruitment is more, and cost is relatively big, has become as the bottleneck that hybrid rice produces.
Summary of the invention
For solving the problems referred to above, the invention provides the hybrid rice seed breeding process of a kind of entire mechanization, omnidistance machinery
Changing Mixed plant, simplify breeding of hybrid rice program, saved breeding cost, practicality is the strongest.
For achieving the above object, the technical scheme that the present invention takes is:
The hybrid rice seed breeding process of a kind of entire mechanization, comprises the steps:
S1, the hybrid rice that selection Parent duration from seeding to heading is close, import male parent or female parent by brown shell marker gene；
S2, by the Parent of hybrid rice according to seed weight than 1: 5～1: 4 mixing, carry out according to the standard of transplanting
Floppy disk seedling, rice transplanting；
S3, heading flowering period spray hormone GA and release maternal phimosis；
S4, utilizing aircraft to catch up with powder, pollination sprays Bentazon herbicide and removes most male parent；
S5, carry out mechanized harvest, utilize separator the male parent of residual to be removed before warehouse-in, it is thus achieved that highly purified hybridization water
Rice.
The method have the advantages that
Mass mechanized production hybrid rice can be carried out on big farming household, large-scale farm, eliminate the reliance on intensive labor
Power；Simplify production of hybrid seeds program, save breeding cost, adapted to the policy of the novel farmer of national cultivation.
Detailed description of the invention
In order to make objects and advantages of the present invention clearer, below in conjunction with embodiment, the present invention is carried out further
Describe in detail.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not used to limit this
Bright.
Embodiments provide the hybrid rice seed breeding process of a kind of entire mechanization, comprise the steps:
S1, the hybrid rice that selection Parent duration from seeding to heading is close, import male parent or female parent by brown shell marker gene；
S2, by the Parent of hybrid rice according to seed weight than 1: 5～1: 4 mixing, carry out according to the standard of transplanting
Floppy disk seedling, rice transplanting；
S3, heading flowering period spray hormone GA and release maternal phimosis；
S4, utilizing aircraft to catch up with powder, pollination sprays Bentazon herbicide and removes most male parent；
S5, carry out mechanized harvest, utilize separator the male parent of residual to be removed before warehouse-in, it is thus achieved that highly purified hybridization water
Rice.
Actual tests funds expenditure according to various cultivation seed production ways and market survey, we are by the cultivation system of the application
The mode of kind compares with the production cost of conventional rule kind, is shown in Table 1, from the cost consuming the means of production of seed production way
Seeing, transplanting is 372.6 yuan/667m2, the cost of the conventional production of hybrid seeds is the highest, is 607.4 yuan/667m2。
Table 1 cost comparative unit: unit/667m2
Mixed plant mode illustrates with the cost of conventional seed production way:
1, fertilizer: include that base is made in rice seedling bed and land for growing field crops, every 667m2 Diammonium phosphate (DAP) 15kg, carbamide 15kg, potassium chloride 15kg
Fertilizer, imposes BB fertilizer 15kg boot stage.
2, " use of gibberellins " consumption: Mixed plant consumption gibberellins 4g unit/667m2, the requirement male parent of the conventional production of hybrid seeds
Plant slightly above female parent, therefore male parent to spray twice more.
3, results: Mixed plant need not the most first cut male parent to the conventional production of hybrid seeds, saves and cuts the artificial of male parent.
4, water rate: mixed seeding transplanted by machine machinery direct-sowing dry and artificial water direct seeding all eliminate rice seedling bed water, and machinery drought is straight
The seedling stage broadcast, for mixed seeding transplanted by machine and artificial water direct seeding will much less with aqueous phase, need not water.
In sum, originally it is embodied as improving breeding of hybrid rice efficiency, reduces labor intensity and production cost.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For Yuan, under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, these improvements and modifications also should
It is considered as protection scope of the present invention.
