Abstract
The invention discloses a cuttage and rapid propagation method for eustipes of double leaf segments of purple yam, belonging to the propagation method of purple yam. The method comprises the following specific steps of: (1) covering a plastic film and planting parent yam early: ridging, covering the plastic film and planting parent yam early in the first or middle ten days of April every year; (2) carrying out cuttage and rapid propagation of double leaf segments in summer: carrying out cuttage on braches with vigorous growth, short segments and no diseases and insect pest in a cuttage shed covered by a sun-shielding net after 9 in the morning in a sunny day from the ending of July to the beginning of August when the vines of the purple yam nearly climb fully the built propeller strut, shielding light, cooling and insulating heat within 2 weeks after planting, and removing the sun-shielding net until the middle or last ten days of September when the eustipes of the double leaf segments of the purple yam completely survive, thus the purple yam normally grows in the plot; and (3) harvesting miniature purple yam in autumn. The method has the beneficial effects: the propagation coefficient of the purple yam is increased in geometric progression, thus the production cost is lowered; and the obtained miniature yam can be popularized in a large area, and the propagation and spread of the original diseases and insect pests of the purple yam are avoided.
Description
Technical field
The present invention relates to the propagation method of a kind of purple Chinese yam, specifically a kind of purple Chinese yam cauline leaf double leaf joint cuttage and quick-propagation method.The cauline leaf cuttage root-taking that is mainly used in purple Chinese yam is born the numerous soon of micro potato.
Background technology
Chinese yam (Dioscorea opposite Thunb) is the high-efficiency and economic crop of a kind of grain, dish, medicine dual-purpose, also is China's export one of the Specialty vegetable of earning foreign exchange.The purple medicine of Xu Nong be Xuzhou Academy of Agricultural Sciences 2006 from Zhejiang, the ground such as Fujian, Guangxi introduce, screening, and it are carried out purple Chinese yam new varieties of detoxification purification and rejuvenation, because its meat is that purple is gained the name, are feature breeds in the Chinese yam.Purple Chinese yam is rich in anthocyan, and is of many uses, both can make the delicacies on the dining table, the medicinal material that can keep healthy again, and frequent edible purple Chinese yam can reduce blood pressure, blood sugar, anti-ageing lengthening one's life, brain tonic is mended intelligence, strengthens body immunity.Purple Chinese yam is not as the common white Chinese yam, and Chinese yam beans (bulbil) can be tied by the leaf segment place during growth, and next year is again with a large amount of fast numerous its merits of purificating and rejuvenating of Chinese yam beans.The purple Chinese yam of China is the stem tuber rhizome cutting propagation at present, and its reproduction coefficient only is 10～15 times, has greatly limited breeding and the popularization of purple Chinese yam.About the cauline leaf of purple Chinese yam the report of taking root the cuttage and quick-propagation technology so far there are no.
Summary of the invention
The invention provides a kind of purple Chinese yam cauline leaf double leaf joint cuttage and quick-propagation method, purpose is to solve the propagation method of purple Chinese yam, utilizes purple Chinese yam cauline leaf double leaf joint cuttage and quick-propagation to take root and bears micro potato.
The present invention realizes with following technical scheme: a kind of purple Chinese yam double leaf joint cuttage and quick-propagation method specifically comprises the steps:
(1) spring, overlay film was early planted female potato: on annual April, the middle ten days, make ridge, overlay film and early plant female potato, female potato size is 50～80g/ piece; Row spacing 85～90cm, the high 35～40cm in ridge, spacing in the rows 25～28cm, density is 3300 strain/mus;
(2) summer, double leaf saved cuttage and quick-propagation: at the beginning of by the end of July to 8 months, when purple Chinese yam tendril climbs the purple Chinese yam " man-like shelf " of completely taking soon, after fine at 9 o'clock in the morning, choose vigorous, the internode tubbiness of growth, without the branch of damage by disease and insect, every from 3～5 of the double leaf joint cauline leafs of tendril middle part clip semi-lignified; First the bottom stipes is hurt to petiole base in the middle of the stem branch, to break the dormancy of cauline leaf axillalry bud; Use again 3～5 hours hestening rootings of plant growth regulator 100ppm soaked with liquid; Plant after at 15 o'clock in afternoon in the cuttage canopy that is covered with sunshade net; Transplanting medium is farmyard manure, sandy loam, each mixture of 1/3 of river sand in the described cuttage canopy, the wide 110cm of the furrow of transplanting medium, the long 10m of furrow, line-spacing 10～15cm, spacing in the rows 5～8cm; Bottom leaf segment, blade are all imbedded in the matrix, and the top leaf segment places on the stromal surface; And after planting, all carry out shading, cooling and moisturizing in 2 weeks, and its temperature remains on 25 ℃～28 ℃, and humidity remains on 90%～95%; And after planting, carry out intermittent spraying cooling and moisturizing in 2 weeks, be beneficial to cauline leaf growth adventive root; In 9 months, the last ten-days period, purple Chinese yam double leaf joint stipes survives fully, the axillalry bud that namely the top stipes is new removes sunshade net after extracting out again, is allowed to condition at normal growth in the furrow;
(3) gather in the crops purple Chinese yam micro potato autumn: in 10 months, before arrive the Frost's Descent in the last ten-days period, the micro potato that purple Chinese yam cauline leaf cuttage root-taking is born excavates results, and airing moves into indoor storage after 2～3 days in the sun.
The invention has the beneficial effects as follows: the reproduction coefficient of (1) purple Chinese yam has reduced production cost with geometric growth; Need not stripping and slicing when (2) the fast numerous micro potato stem tuber of bearing of cauline leaf double leaf joint is done kind of next year damaged, emerge early, well developed root system, output is high; (3) micro potato of bearing with the cauline leaf cuttage carries out spread, the propagation that can avoid the original soil-borne disease insect pest of purple Chinese yam with spread.
