Abstract
The invention provides a hybrid pumpkin seed production method. The hybrid pumpkin seed production method includes the steps of seedling growing in a greenhouse, soil preparation, field planting, field management, hybrid seed production and harvesting, and the inbred line HCD-2-3 as a male parent and the inbred line QYC-5-1 as a female parent are adopted to be crossbred to produce hybrid seeds. Compared with the conventional pumpkin seed production method, the method can avoid the rainy season at the late stage to obtain high-yield, stable-yield and high-quality seeds 20 to 30 days early.
Description
Technical field
The present invention relates to field of plant breeding, be specifically related to a kind of method of the squash hybridization production of hybrid seeds.
Background technology
Pumpkin popular name pumpkin, pumpkin are annual dicotyledonous herbaceous plant, but dish is with, edible when ripe when fruit is tender, and seed can be eaten.Along with the research of pumpkin nutrient health-care effect and the large-scale production of product, the whole nation to high-quality pumpkin F1 for the seed demand trend that is that supply falls short of demand.Yet seed yield is widely different between pumpkin production of hybrid seeds year border, and tracing it to its cause mainly is the weight that how much depends on pumpkin later stage disease of pumpkin seed yield, and the weight of disease depends on whether suitable pumpkin late growing stage is grown when year-climate.
Summary of the invention
Technical problem to be solved by this invention provides a kind of method of the squash hybridization production of hybrid seeds, and this method is done sth. in advance 20 ~ 30 days than conventional pumpkin producing method for seed, can avoid rainy season in later stage, obtains stable high yield, high quality seed.
The technical scheme that the present invention adopted is:
A kind of method of the squash hybridization production of hybrid seeds comprises and nurses young plants in hothouses, puts in order ground, field planting, field management, hybrid seeding, results step.This method with inbred line HCD-2-3 make male parent, inbred line QYC-5-1 makes hybridization of female parent improved crossing kind.
Precocious, disease-resistant, the young melon of inbred line HCD-2-3 is shiny black, melon meat yolk, and article are of fine quality; Inbred line QYC-5-1 extremely early mature, disease-resistant, young melon be dark green to have decorative pattern, and article are of fine quality.
Saidly nurse young plants in hothouses to behind male parent HCD-2-3 seed soaking 4h, the 30 ℃ of vernalization 20h seeding and seedling raising, every 1m
2Sow 500; Behind maternal QYC-5-1 seed soaking 4h, the 30 ℃ of vernalization 20h, seeding and seedling raising, per 1 m
2Sow 500.
It is said that irrigation and drainage are convenient in order to select wholely, multiplication fields is made, per 667 m in the smooth plot of physical features
2Execute fertile 4000 kg of farming, nitrophosphate fertilizer 25 kg, potassium dihydrogen phosphate 5 kg; Deep plough, rake, 3 m make groove by line-spacing, promptly scrape out the groove that is lower than ground 15 cm with spade, are convenient to irrigate.
Said field planting be with male parent, maternal field planting at groove, the male parent field planting is at two ends, the pollination of being convenient to pick flowers; Male parent, maternal spacing in the rows are 0.5 m; Per 667 m
2Maternal 400 strains of field planting, male parent 40 strains, male parent is 1 ︰ 10 with the capable ratio of female parent; After the field planting, spray 2000 ~ 3000 times of liquid of 5 % Imidacloprid missible oil and prevent eliminating aphis; Water, detain little shed.
Said field management is to be main with short root strong sprout before bloom after the field planting, when seedling grows to 4 ~ 5 true leaves, topdresses on a small quantity in conjunction with watering; When fine temperature is high, raise little shed two ends and central authorities, in time leaking informaton prevents to burn seedling; Field planting removes little shed according to weather condition in the time of 30 days ~ 45 days; Intertill deeply to improve ground temperature after removing canopy; Rogueing finds that suspicious strain takes out immediately; Training is kept down the vines of a creeping plant, maternal two climing formula trainings, male parent three climing formula trainings; The potassium dihydrogen phosphate of foliage-spray 0.2 % 1 time.Whole seedling management is accomplished early to send out short strong sprout, and one urgees on earth, strives the early flowering pollination.
When said hybrid seeding is initial bloom stage, all male flowers in the maternal strain are beaten only, guaranteed that no male flower is open in the maternal field of pollination phase, keep all male flowers on the paternal plant, extract all female flowers or young fruit in conjunction with pruning to keep down the vines of a creeping plant; During pollination, select in male parent, maternal field noon before that day respectively and mark was about to open male parent male flower and maternal female flower in second day, uses the knitting wool embroider; The next morning 6:00 ~ 10:00 takes off the knitting wool on the female flower, gently strip off female flower corolla; The male parent male flower is taken, removed corolla and expose flower pesticide, male flower pollen is put on the female flower column cap equably; With knitting wool the female flower corolla is hitched, a general male flower can be awarded 3 ~ 5 female flowers again; After the pollination beginning, the liquid manure demand is big, waters once in per 7 days, topdresses once agricultural chemicals of sprinkling in per 10 ~ 15 days in per 15 days.
Said results are pollination back 35 ~ 40 days, when fruit begins painted maturation, gather, and must notice when gathering whether the fruit of being adopted has this varietal characteristic, can't adopt into assorted strain fruit, and mellow fruit and not full ripe fruit is placed apart; After-ripening is 10 ~ 20 days after gathering, and the seed of process after-ripening is full, germination rate is strong, thousand kernel weight is high; Will fruit when drawing kind with thick angle of throat crosscut fruit, in order to avoid cut brokenly seed; Flat son is cleaned, floated to the seed that takes out with clear water; Seed dries after cleaning; Treat further to select after seed moisture content is reduced to below 7%, remove foreign material such as not plump seed, sand grains, make cleanliness reach 100%, mark batch, packing warehouse-in.
Compared with prior art; The present invention has following remarkable advantage and beneficial effect: the present invention is warm, not strict to temperature requirement according to pumpkin happiness, have stronger moisture-proof power and drought-enduring power, the well developed root system absorbing capacity by force, feature such as adaptability is strong; Employing is nursed young plants in hothouses, little shed is cultivated, land for growing field crops artificial hybridization is pollinated and bred crossbreed F1 generation; Do sth. in advance 20 ~ 30 days than conventional pumpkin producing method for seed; And can avoid rainy season in later stage, stable stable high yield, the high quality seed of obtaining, general per 667 m
2Hybrid seed 60 kg are produced in maternal 400 strains of field planting, male parent 40 strains.This squash hybridization producing method for seed production of hybrid seeds is reliable and stable, can be used for actual test, at present in further test and applies in Henan Province.
Embodiment
Below in conjunction with embodiment the present invention is made further specific descriptions, but be not limited to this.
