Description
Technical field
The present invention relates to a kind of method improving vegetables production of hybrid seeds ripening rate, particularly relate to a kind of method improving kohlrabi production of hybrid seeds ripening rate, belong to plant seeding technique field.
Background technology
Kohlrabi, also known as kohlrabi (BrassicaolereceaL.var.caulorapa), is Cruciferae, Vegetables in Brassica, originates in European Mediterranean to the North Sea littoral.Purple kohlrabi, white kohlrabi, blue or green kohlrabi etc. is divided into by ball look.Kohlrabi Leaf-feeding insects is the fleshy stem expanded, and meat is pure white, the thin meat of skin is crisp, have the mouthfeel of similar pear, apple, can ripely eat also to can be used as fruit and eat raw.Kohlrabi is nutritious, and containing higher anthocyan, raw fiber, mineral matter, contained vitamin C is equivalent to Citrus.Due to Peculiar Forms, beautiful in colour, also can be used as ornamental crops and to plant for park, garden or potted plant.
Kohlrabi producing method for seed mainly contains the kind that systematic breeding proterties is excellent from routine kind, and protospecies breeding is applied to production; Or the crossbreed combination that the proterties of the self-incompatible material formulation of Selection utilization is excellent, parent material hybridization preparation F
1generation and utilize male sterile line and hybridization between selfed lines to prepare F
1in generation, is applied to three kinds of forms such as production.The production of hybrid seeds is the final step of breeding of new variety, and be also a step of most critical, some kohlrabi parent can make in experimental field and combine, but the production of hybrid seeds under field conditions (factors), and be difficult to numerous go out seed.Because kohlrabi " Cruciferae " belongs to cross pollinated plant, pattern is also bright-coloured there is no obvious difference in appearance compared with the equal crop such as rape, wild cabbage, but nectary flourishing not (different cultivars is variant).By the pollination such as insect, wind, mainly by honey bees pollination.Kohlrabi flowering stage is mid-April, though slightly more late than rape, but overlapping with many plant full-bloom stages, be no lack of kind honeybee being had more to temptation in these plants, therefore can attract most honeybee, even if it is also of no avail that seed farm puts honeybee in a large number, have a strong impact on the pollination of production of hybrid seeds kohlrabi, directly cause ripening rate to decline, hybrid seed yield is low, breeding work, falls short of success for lack of final effort.
Summary of the invention
The technical problem that the present invention solves: overlapping with many plant full-bloom stages for flowering stage for kohlrabi, because nectary is flourishing not, be attracted away most honeybee, even if it is also of no avail that seed farm puts honeybee in a large number, have a strong impact on the pollination of production of hybrid seeds kohlrabi, directly cause the defect that ripening rate declines, the present invention takes to regulate sowing time, rich water is planned strategies for, pinch, pruning sprays hormone, adding essence at production of hybrid seeds full-bloom stage root outer spraying water-soluble amino acids fertilizer attracts the cultivation steps such as honey bees pollination to create good pollination environments, thus raising ripening rate, and then increase hybrid seed yield.
Technical scheme: the method for raising kohlrabi production of hybrid seeds ripening rate provided by the invention, comprises the following steps:
Postpone in step one, kohlrabi production of hybrid seeds sowing time in 9 months, the last ten-days period, seedling age 20-25 days starts to heel in and cultivates kohlrabi strong sprout;
Step 2, kohlrabi production of hybrid seeds field planting control water after living, only otherwise meeting with arid does not just rewater; Control bulb within 3-4cm, existing certain nutrient accumulation, have again certain cold resistance, bulb is larger, more easily endures cold when surviving the winter;
Step 3, kohlrabi budding after stem pinching when growing to 10-15cm, remove the center flower bud of 1/5-1/4, every mu of spread manuer in holes 10-15Kg urea and 25-30Kg Nitrogen, Phosphorus and Potassium (15-15-15 type) promote that primary branch grows subsequently; Pinch when primary branch grows into 15-20cm, promote that Secondary branches is grown, manual removal bottom flower, suitably puts off flowering time;
Step 4, kohlrabi seed farm put 2-3 case honeybee (2-3 ten thousand) full-bloom stage every mu, and root outer spraying 0.5-0.8% water-soluble amino acids fertilizer adds 0.5-1% essence mixed solution 100-120Kg, attract honey bees pollination, increase considerably astragalus adsurgens quantity;
Step 5, kohlrabi later stage spraying concentration of blooming is the gibberellin 100-120Kg of 250-300ppm, and undershoot portion bar Blooming in promotion, ensures later stage flower, have the enough nutrient accumulation time after pollination.
Beneficial effect: control growth before the inventive method adopts and survives the winter, significantly reducing kohlrabi bulb survives the winter because of the rotten risk by freeze injury, moderate retardation flowering time avoids the florescence of the good crop of the nectary such as rape, wild cabbage, honey bees pollination is attracted at the fertile essence of production of hybrid seeds full-bloom stage root outer spraying water-soluble amino acids, the measures such as later stage Accelerate bloom, thus improve production of hybrid seeds ripening rate, and then improve kohlrabi hybrid seed yield.
