Abstract
The invention discloses a method for improving the seed production yield of a sterile line of cabbage vegetables. Under an isolated condition, male and female parents of the cabbage vegetables are sowed; a sugarcane juice water solution is sprayed on the female parents at a full-blossom period until a final flowering period; the solution is sprayed once every day and all the male parents are removed at the final flowering period; and when seeds are ripe, the seeds can be harvested from the female parents. According to the method, the sterile-line female parents attract bees by virtue of the sugarcane juice water solution and pollination is finished by the honeys so that the seed production yield is greatly improved, the method is simple and easy to operate and the effect is obvious.
Description
Technical field
The present invention relates to and a kind ofly improve the method that cole vegetables utilizes sterile lines seed making output, belong to field of plant growing technology.
Background technology
Cole vegetables comprises the various vegetables such as wild cabbage, cabbage mustard, broccoli, Cauliflower, western blue a kind of sedge.The edible organs of cole vegetables is nutritious, containing multivitamin, mineral matter, is especially rich in vitamin C.Can for stir-frying and eating, eating raw or process pickled.
Used cole vegetables seed is all crossbreed in the market, in hybrid seeding, have and utilize Parent to be all the self incompatible line production of hybrid seeds, also having a kind of is utilize female parent to be the cytoplasm male sterility line production of hybrid seeds, utilize the cytoplasm male sterility line production of hybrid seeds, there are two advantages relative to utilizing the self incompatible line production of hybrid seeds: (1) can ensure that the purity of crossbreed is 100%, unlike utilizing the self incompatible line production of hybrid seeds, more or less have a little self-fruitful pseudostationary inside; (2) the F1 generation seed using cytoplasmic male sterilty to produce is also male sterile, can ensure that breeding material does not outflow.
Because these two advantages above-mentioned, on market, increasing kind is all utilize the cytoplasm male sterility line production of hybrid seeds.But cytoplasm male sterility line, compared with self incompatible line, has two major features: (1) does not have pollen; (2) nectary is undeveloped.The production of hybrid seeds of wild cabbage class is all by honeybee to complete pollination, but these two features of cytoplasm male sterility line, and cause honeybee not like presence, this will affect hybrid seed yield.
Summary of the invention
The technical problem solved: the deficiency existed for prior art, the invention provides a kind of being easy to operate, effectively can improve the method that cole vegetables utilizes sterile lines seed making output, the method effectively can attract honeybee, relies on honeybee to complete pollination, thus improves hybrid seed yield.
Technical scheme: provided by the inventionly a kind ofly improve the method that cole vegetables utilizes sterile lines seed making output, it comprises the following steps:
(1) sowed by the Parent of cole vegetables, wherein said female parent is male sterile line;
(2) treat the maternal full-bloom stage of cole vegetables, only the sugar-cane juice aqueous solution is sprayed to female parent, once a day, until spend eventually;
(3) when cole vegetables is spent eventually, male parent is all removed;
(4) during seed maturity, in female parent results seed.
The described sugar-cane juice aqueous solution is mixed by the sugar-cane juice of fresh squeezing and clear water, and the mixed proportion of sugar-cane juice and clear water is 1:10 ~ 20; Preferably, the mixed proportion of described sugar-cane juice and clear water is 1:10.
Described sugar-cane juice aqueous solution spraying time is every morning 8 or dusk 6 points, and spraying consumption is 10 ~ 15 liters every mu.
Beneficial effect: the present invention, on the basis of traditional sterile lines seed making method, sprays the sugar-cane juice aqueous solution by full-bloom stage to parent male sterile line, attracts honeybee to complete pollination, improves hybrid seed yield.Method is simple to operation, successful.
Embodiment
Mode below by embodiment further illustrates the present invention, but therefore protection scope of the present invention is not confined to following embodiment, but is limited by specification of the present invention and claims.
Embodiment 1
Mid-August, under isolation condition, the female parent (male sterile line) risen in the head cabbage varieties winter is sowed with male parent; April next year, bolting was bloomed, and select full-bloom stage every morning 8 and spray the sugar-cane juice aqueous solution (mixed proportion of sugar-cane juice and clear water is 1:10) to female parent, spraying consumption is 10 liters every mu, until colored eventually; Eventually during flower, male parent will be risen the winter and all remove; By the end of June, during seed maturity, in female parent results seed.
Comparative example 1
Mid-August, under isolation condition, the female parent (male sterile line) risen in the head cabbage varieties winter is sowed with male parent; April next year, bolting was bloomed, full-bloom stage every morning 8 to maternal spray concentration be 1% white sugar water solution, spraying consumption is 10 liters every mu, until flower eventually; Eventually during flower, male parent will be risen the winter and all remove; By the end of June, during seed maturity, in female parent results seed.
Embodiment 2
Mid-August, under isolation condition, the female parent (male sterile line) risen in the head cabbage varieties winter is sowed with male parent; April next year, bolting was bloomed, and select full-bloom stage every morning 8 and spray the sugar-cane juice aqueous solution (mixed proportion of sugar-cane juice and clear water is 1:15) to female parent, spraying consumption is 12 liters every mu, until colored eventually; Eventually during flower, male parent will be risen the winter and all remove; By the end of June, during seed maturity, in female parent results seed.
Comparative example 2
Mid-August, under isolation condition, the female parent (male sterile line) risen in the head cabbage varieties winter is sowed with male parent; April next year, bolting was bloomed, full-bloom stage every morning 8 to maternal spray concentration be 1% white sugar water solution, spraying consumption is 12 liters every mu, until flower eventually; Eventually during flower, male parent will be risen the winter and all remove; By the end of June, during seed maturity, in female parent results seed.
Embodiment 3
Mid-August, under isolation condition, the female parent (male sterile line) risen in the head cabbage varieties winter is sowed with male parent; April next year, bolting was bloomed, and select full-bloom stage every morning 8 and spray the sugar-cane juice aqueous solution (mixed proportion of sugar-cane juice and clear water is 1:20) to female parent, spraying consumption is 15 liters every mu, until colored eventually; Eventually during flower, male parent will be risen the winter and all remove; By the end of June, during seed maturity, in female parent results seed.
Comparative example 3
Mid-August, under isolation condition, the female parent (male sterile line) risen in the head cabbage varieties winter is sowed with male parent; April next year, bolting was bloomed, full-bloom stage every morning 8 to maternal spray concentration be 1% white sugar water solution, spraying consumption is 15 liters every mu, until flower eventually; Eventually during flower, male parent will be risen the winter and all remove; By the end of June, during seed maturity, in female parent results seed.
When cultivation management is identical, full-bloom stage is not carried out the hybrid seed yield of any operation as blank to female parent, compare with the output of each embodiment and comparative example, result is as shown in table 1:
Table 1 cole vegetables hybrid seed yield compares
As can be seen from Table 1, spray the sugar-cane juice aqueous solution in full-bloom stage every day to female parent, hybrid seed yield is much higher than and sprays white sugar water solution and the natural production of hybrid seeds every day at full-bloom stage.It can thus be appreciated that the plant sugar fragrance contained in the sugar-cane juice aqueous solution can attract honeybee to come to pollinate, thus greatly improves the output that cole vegetables utilizes the male sterile line production of hybrid seeds.Can find out that the method is simple by test.Can determine thus, the present invention has promotional value aborning.
