Description
Technical field
The present invention relates to a kind of method for improving vegetables production of hybrid seeds setting percentage, more particularly to a kind of raising kohlrabi production of hybrid seeds setting percentage
Method, belong to plant seeding technique field.
Background technology
Kohlrabi is also known as kohlrabi（Brassica olerecea L.var.caulorapa）, it is Cruciferae, Brassica genus
Vegetables, originate in Mediterranean to the North Sea, Europe littoral.It is divided into purple kohlrabi, white kohlrabi, blue or green kohlrabi etc. by ball color.Kohlrabi Leaf-feeding insects are
The fleshy stem expanded, meat is pure white, thin skin meat is crisp, have the mouthfeel of similar pear, apple, ripe can eat and also be eaten raw as fruit.
Kohlrabi is nutritious, and containing higher anthocyanidin, crude fibre, mineral matter, contained vitamin C is equivalent to Citrus.Due to form
Peculiar, beautiful in colour, also can be used as ornamental crops is used for park, garden plant or potted plant.
Kohlrabi producing method for seed mainly has the excellent kind of systematic breeding character from conventional plant, and protospecies breeding is applied to life
Production；Or the excellent cenospecies combination of the character prepared of the self-incompatible material of Selection utilization, parent material hybridization prepares F1Generation
And utilize male sterile line and hybridization between selfed lines preparation F1In generation, is applied to three kinds of forms such as production.The production of hybrid seeds be breeding of new variety most
Latter step, is also a step of most critical, and some kohlrabi parents can make in experimental plot to be combined, but is made under field conditions (factors)
Kind, and be difficult it is numerous go out seed.Because kohlrabi " Cruciferae " belongs to cross pollinated plant, pattern is also bright-coloured equal with rape, wild cabbage etc.
Crop is compared and has no significant difference in appearance, but nectary is not flourishing enough（Different cultivars is variant）.Passed by insect, wind etc.
Powder, mainly by honey bees pollination.Kohlrabi florescence is mid-April, though it is slightly more late than rape, it is overlapping with many plant full-bloom stages, this
It is no lack of the kind that temptation is had more to honeybee in a little plants, therefore can attracts to walk most honeybee, even if seed farm is largely put
Honeybee is also of no avail, has a strong impact on the pollination of production of hybrid seeds kohlrabi, directly results in setting percentage decline, and hybrid seed yield is low, breeding work, work(
A thanks to basket for holding earth.
The content of the invention
Present invention solves the technical problem that：It is overlapping with many plant full-bloom stages for kohlrabi florescence, because nectary is not enough sent out
Reach, be attracted away most honeybee, it is also of no avail largely to put honeybee even if seed farm, have a strong impact on the pollination of production of hybrid seeds kohlrabi, directly
The defect for causing setting percentage to decline is connect, the present invention takes regulation sowing time, rich water is planned strategies for, pinched, pruning sprays hormone, in the production of hybrid seeds
Full-bloom stage root outer spraying water-soluble amino acids fertilizer perfuming essence attracts the cultivation steps such as honey bees pollination to create good pollination environments, from
And setting percentage is improved, and then increase hybrid seed yield.
Technical scheme：The method for the raising kohlrabi production of hybrid seeds setting percentage that the present invention is provided, comprises the following steps：
Step 1: kohlrabi production of hybrid seeds sowing time postpone into September, the last ten-days period, seedling age starts to heel in cultivation kohlrabi for 20-25 days and strengthened
Seedling；
Step 2: water is controlled after living of kohlrabi production of hybrid seeds field planting, as long as not rewatered without meeting with arid；Bulb is controlled in 3-
Within 4cm, existing certain nutrient accumulation has certain winter resistance again, and bulb is bigger, is more easily endured cold when surviving the winter；
Step 3: kohlrabi budding after stem pinching when growing to 10-15cm, remove 1/5-1/4 center flower bud, subsequent every mu of cave
Apply 10-15Kg urea and 25-30Kg NPKs（15-15-15 types）Promote primary branch growth；When primary branch is grown into
Pinched during 15-20cm, promote Secondary branches development, manual removal bottom flower suitably puts off flowering time；
Step 4: kohlrabi seed farm puts 2-3 case honeybees for every mu in full-bloom stage（2-3 ten thousand）, root outer spraying 0.5-0.8% water
Dissolubility amino acid fertilizer adds 0.5-1% essence mixed solution 100-120Kg, attracts honey bees pollination, increases considerably astragalus adsurgens number
Amount；
Step 5: kohlrabi blooms, later stage spraying concentration is 250-300ppm gibberellin 100-120Kg, undershoot portion in promotion
Bar Blooming, it is ensured that the later stage is spent, and has the enough nutrient accumulation time after pollination.
Beneficial effect：The inventive method significantly reduces kohlrabi bulb and survived the winter because by freeze injury using growth is controlled before surviving the winter
And rotten risk, moderate retardation flowering time avoids the florescence of the good crop of the nectarys such as rape, wild cabbage, in production of hybrid seeds full-bloom stage root
The outer fertile essence of water-soluble amino acids that sprays attracts honey bees pollination, the measure such as later stage Accelerate bloom, so as to improve production of hybrid seeds setting percentage, enters
And improve kohlrabi hybrid seed yield.
