Abstract
The invention discloses a three-segment healthy purple micro yam breeding method, and belongs to the field of yam seedling breeding methods. The three-segment rapid yam seedling breeding method is utilized in the seedling growing method, healthy micro yam seedlings without soil-borne diseases and yam-borne diseases are produced from purple yam seedlings without yam tubers and are non-contact with soil, factorial production is implemented, a large amount of healthy micro yam seedlings are bred intensively, breeding efficiency of purple yam seedlings can be improved, and production cost can be reduced. Yield of purple yams is increased by 15 to 20% per mu, original fine species and yield of the purple yams are recovered, and planting benefits of soil per unit area is increased.
Description
Technical field
The present invention relates to Chinese yam potato seed mating system field, relate in particular to a kind of healthy purple Chinese yam micro potato three section type mating system.
Background technology
Chinese yam (Dioscorea opposite Thunb), for the perennial herbaceous stem prehensile of Dioscoreaceae Dioscorea liane, is the high-efficiency and economic crop of a kind of grain, dish, medicine dual-purpose, is also China's export one of the Specialty vegetable of earning foreign exchange, and all there is plantation all parts of the country.Purple Chinese yam is rich in anthocyan, of many uses, both can make the delicacies on dining table, can make again health-care medicinal, and often edible purple Chinese yam can reduce blood pressure, blood sugar, anti-ageing lengthening one's life, and brain tonic is mended intelligence, strengthens body immunity.But purple Chinese yam is not as Chinese yam, and when growth, Chinese yam beans (bulbil or bulbil) can be tied by leaf segment place, next year is again with a large amount of fast numerous its good strains of seeds of purificating and rejuvenating of Chinese yam beans.The purple Chinese yam of China produces and is underground stem tuber rhizome cutting propagation at present, and its reproduction coefficient is only 10-15 times, has greatly limited breeding and the popularization of purple Chinese yam, and long-term stripping and slicing vegetative propagation, has reduced the original good strains of seeds of purple Chinese yam and output.
Summary of the invention
In order to improve the reproduction coefficient of purple Chinese yam potato seed, reduce production costs, recover the original good strains of seeds of purple Chinese yam and output, the invention provides a kind of healthy purple Chinese yam micro potato three section type mating system.Utilize three section type Chinese yam potato seed fast breeding method, to not produce the healthy miniature seed without soil-borne disease and the former disease of potato with potato piece with the purple Chinese yam potato seedling that does not contact soil, realizing batch production produces, concentrate and cultivate a large amount of healthy miniature seeds, be conducive to improve purple Chinese yam potato seed reproductive efficiency, reduce production costs.
The present invention realizes with following technical scheme: a kind of healthy purple Chinese yam micro potato three section type mating system, and concrete steps are:
(1) in purple Chinese yam potato seed booth, stripping and slicing is grown seedlings the stage: in annual 15-25 day in March, select the purple medicine of Xu Nong, Huangyan purple to transplant the purple Chinese yam improved seeds such as medicine, improve purple Chinese yam potato seedling quality with three section type seedling-cultivating method, strive that seedling is many, Miao Yun, Miao Zhuan, seedling early send out, for producing autumn in a large number, high-quality, the miniature purple Chinese yam potato seed of health lay the first stone; Select anosis, without worm, without the potato piece of freeze injury, by purple Chinese yam potato seed stripping and slicing, standard is 50-60g/ piece; Then mix sterilization seed dressing with carbendazim or mancozeb original powder and quicklime powder in 1:3 ratio, and bask seeds or high-temperature healing; Stripping and slicing back, in, tail is separately big arch shed, small arched shed, mulch film propagating seeding in cold frame with booth 3 films, density is 15-20kg/m
2;
(2) in purple Chinese yam potato seedling small arched shed with the numerous seedling of the seedling stage: 5-10 day in May, in small arched shed, by line-spacing 15-18cm, spacing in the rows 5-8cm, the wide 90-100cm of furrow, after the potato seed height of seedling of 3-5 leaf segment is cut with Miao Fanmiao; Cut Miao Houxian bottom minor matters are hurt to petiole base from minor matters centre pocket knife, to break the dormancy of cauline leaf axillalry bud; Again by 3-5 minute hestening rooting of 100ppm root-inducing powder immersion bubble; After planting, adopting three height is high temperature, high humidity, high fertile cultivation management technology, reaches the tiller of taking root completely and survives seedling, prepares against the later stage and plants into land for growing field crops;
(3) the purple Chinese yam potato seedling land for growing field crops breeding health micro potato stage: 11-15 day in June, the purple Chinese yam seedling band root that the tiller of taking root is completely survived is planted into breeding land for growing field crops; Purple Chinese yam seedling is planted appropriate to the occasion high density furrow and is done, the wide 100-110cm of furrow, the high 10-15cm of furrow, furrow spacing 20-30cm; Line-spacing 18-20cm, spacing in the rows 8-10cm, density is 10000-12000/mu; While planting with 5% carbosulfan granule and 3% phoxim granule mixed in equal amounts, the row replacement of 2-2.5kg/ mu; Or the 30% Phoxim microcapsule agent of 1:5 dips in root 5 minutes, to prevent and treat the harm of purple Chinese yam root-knot nematode and grub;
(4) the healthy micro potato field management of purple Chinese yam: be cauline leaf growth animated period August, requires purple Chinese yam overground part growing way balance, and anti-excessive growth, controls prosperous length.The prevention and control cauline leaf excessive growth such as available paclobutrazol, S 3307; Use 2 kinds of liquids of Prochloraz or benzene miaow methyl cyclic-azole and mancozeb or carbendazim and separately spray 1-2 time, interval 5-7 days, for preventing and treating Chinese yam anthracnose; Be the quick expanding stage of healthy micro potato potato piece September, requires the steady long not prosperous length of purple Chinese yam overground part, anti-early ageing, and short potato piece expands soon; By control cauline leaf early ageing phenomenons such as 0.2% potassium dihydrogen phosphates;
(5) the healthy micro potato results of purple Chinese yam and storage: 15-20 day in October, purple Chinese yam leaf look, gradually by green flavescence, is tending towards ripe, should gather in the crops healthy purple Chinese yam micro potato in good time, and general output is 15-25g/ grain, 30000-35000 grain/mu; To 1000-1200 times of carbendazim spray disinfectant for purple Chinese yam potato seed, if there be bad rotten can only the sprinkling with quicklime powder of part potato seed, make sure to keep in mind to stir potato seed; Purple Chinese yam Winter safety reserve temperature is 15-18 DEG C.
The invention has the beneficial effects as follows: (1) utilizes three section type Chinese yam potato seed fast breeding method, will not produce healthy miniature seed with potato piece with the purple Chinese yam potato seedling that does not contact soil, avoided the propagation of the original soil-borne disease of purple Chinese yam and the former disease of potato and spread.(2) realize batch production and produce, concentrate and cultivate a large amount of healthy miniature seeds fast, be conducive to improve purple Chinese yam potato seed reproductive efficiency, reduced production cost.(3) healthy miniature seed is emerged soon, has extended breeding time, and Miao Qi, per mu, mu strong, mu morning, general purple Chinese yam per mu yield increase 15-20%, recovers the original good strains of seeds of purple Chinese yam and output, has improved Land Units area planting benefit.
