Abstract
The invention relates to a novel method for green house wintering breeding of sweet potato stems, which solves the problems that in the traditional sweet potato breeding, the potato seeds are required to be preserved through wintering, storage cellars are occupied and the facility consumption is increased, the breeding cost is high, the mature seedlings are weak, and the seedlings have rhizoid and are easily infected. Through a brand-new special sweet potato cultivation method, sweet potato seeds which have no rhizoid, can be named as semi-virus-free seedlings, reduce the generation of root rot and nematode disease, have strong, green and thick stems, strong disease-resistant ability and high survival rate, reach the level of special grade, achieve yield increase of 750 to 1000g per Chinese acre, come into the market early, and have good economic benefit, can be cultured, and are especially suitable for large-area planting in the North of China.
Description
Technical field
The invention belongs to the technical field of Ipomoea batatas cultivation, be specifically related to a kind of new method for raising seedling of sweet potato stem over winter in greenhouse.
Background technology
Known to the inventor, present known cultivation method of sweet potato is to select potato seed from the Ipomoea batatas of last one year results, make naked formula cultivation seedling-cultivating spring, tradition is grown seedlings at first will solve the problem that potato seed is survived the winter and preserved, both taken manpower, material resources, increase facility consumption such as storage vault cellar for storing things again, improved seedling cost, a little less than the Cheng Miao of cultivation, thin per hundred weight of stem have only below 500 grams, do not reach advanced standard, and rice shoot band coring is easily caught an illness, and easily carries root rot and nematodosis secretly, the not high seedling-slowing stage of survival rate is all more than 10-15 days, also will occur simultaneously changing the dead leaf phenomenon of seedling, greatly reduce and lacked vegetative period, amount is given birth in influence.
Summary of the invention
The objective of the invention is for overcoming with deficiency, what provide a kind ofly omits the potato seed preservation of surviving the winter, and does not take the storage vault cellar for storing things, saves and drops into, and seedling cost is low, and seedling is strong, and stem is prosperous, and resistance against diseases is strong, the new method for raising seedling of sweet potato stem over winter in greenhouse that survival rate is high.
The present invention is achieved in that described new method for raising seedling of sweet potato stem over winter in greenhouse.It is characterized in that selecting in mid-September that kind is excellent in the big field of Ipomoea batatas, growing way is strong, the Caulis Ipomoea of no damage by disease and insect is climing, with stem climing connect to cut cut length and be 15 centimetres, then move that to be inserted into smooth pre-rice transplanting ground fast, key points for operation are trench digging straight cuttings, 10 centimetres of furrow widths, 10 centimetres of ditch depths, 15 centimetres of line-spacings, 2 centimetres of spacing in the rows, the earth backing that waters gently buries, about 400 of square metre plant; Mid or late November, look temperature in the time of 10-15 ℃, the climing seedling of stem is moved people's booth, the standard of transplanting is 35 centimetres of line-spacings, and 20 centimetres of spacing in the rows, method are the trench digging straight cuttings, and earth backing waters, about 1000 of mu plant; During climate and other natural phenomena of a season Winter Solstice to the beginning of spring, potato is climing apart from the symptom of a trend 50 centimeters in the booth, adds one deck plastic freezing-proof barrier film, during the climing seedling of the stem egersis that earns a bare living not long; Before and after 1 year rainwater climate and other natural phenomena of a season, the temperature rises, throw off antifreeze barrier film, mid-March, look the climing seedling length of booth stem, divide two kinds of methods to carry out secondary and grow seedlings, a. per 20 centimetres is that a strain standard seedling is cut out, this phase cuts out seedling and is called the climing seedling of secondary stem, and the climing seedling of secondary stem is moved by standard-required again insert other booth subsequently; B. the employing level is pressed and is buried method, and the climing level of the stem about a chi is pressed in 2 centimetres of dark shallow ridges, buries climing dew leaf, appears.After one week, each leaf segment place, it is climing to grow seedling naturally, and a mu raising seedling rate can reach 400%.
Adopt new method for raising seedling of sweet potato stem over winter in greenhouse of the present invention, omit the potato seed storage link of surviving the winter, do not take the storage vault cellar for storing things, saved the input of potato piece, alleviated labour's input, the Cheng Miao of output is not with coring, can be described as half detoxic seedling, reduced root rot, growing of nematodosis, the climing seedling of stem is strong, and is dark green, stem is thick, resistance against diseases is strong, and the survival rate height reaches superfine seedling, at the climing seedling of field planting stem potato piece seedling per hundred heavy 3-5 jin more traditional than plantation, thick 7 millimeters of stem goes out 2-4 rank than the superfine height of seedling of national Specification, about the average volume increase of mu 1500-2000 jin, the climing seedling seedling-slowing stage of plantation stem is short, change seedling hardly, do not fall leaves, prolong about the two weeks in vegetative period, thereby can early go public the average economic well-being of workers and staff 600-1000 unit of improving of mu.
Embodiment:
The present invention is described in further detail below in conjunction with embodiment, plant experimentally the above beneficial effect of getting as the present invention in Shanxi Province Yangquan Suburb Xingcai Wanmuyuan large tracts of land after, prepare this year and in the whole city, district's scope, promote again.
