Abstract

The invention relates to an overwintering method for protecting purple sweet potato planted seedlings, belongs to a sweet potato propagation method and aims to solve the problems of high risk and very high cost of the conventional cellar overwintering method for protecting sweet potato root tubers. The method is characterized by comprising the following steps of: selecting thick and disease-free stems while harvesting in autumn, cutting each stem into segments at the interval of every 2 to 3 sections and planting the segments into a field; building a shed frame facility covered with a double-layer plastic film when the local air temperature is below 10 DEG C and covering another layer of plastic film when the local air temperature is below 0 DEG C so as to ensure that the air temperature in the shed frame facility is above 0 DEG C; removing the lastly covered plastic film when the local air temperature is above 10 DEG C in spring of the next year so as to increase illumination for promoting the germination and leaf growing of the planted seedlings; removing the covered plastic film and detaching the shed frame facility when the local air temperature is above 15 DEG C and applying a fertilizer at the right time so as to promote the growth of the seedlings; and when a fresh seedling has more than two stems, cutting the seedling at the right time to obtain a first batch of fresh seedlings for transplanting. After the method is implemented, the risk of an overwintering process is lowered effectively and overwintering cost for protecting the seedlings is lowered by over 80 percent.

Description

A kind of drinamyl sweet potato is planted seedling over wintering method
Technical field: the present invention relates to a kind of sweet potato propagation method, particularly a kind of drinamyl sweet potato is planted seedling over wintering method.
Background technology: the drinamyl sweet potato has another name called purple sweet potato, the drinamyl Ipomoea batatas.Formal name used at school is mountain, a river purple, is that China scientific and technical personnel introduce the sweet potato new varieties of breeding success from the Kawasaki, Japan farm.The potato skin of this sweet potato is purplish red nearly black, and potato meat is aubergine also, so gain the name.Analyze according to Japanese agricultural product inspection center, the nutrient composition content of the purplish red potato in mountain, river is apparently higher than common Ipomoea batatas, the content of its lysine, copper, manganese, potassium, zinc is higher than 3~8 times in general Ipomoea batatas, long-term edible has step-down, enriches blood, the effect of beneficial gas, moistening lung, beauty treatment; Simultaneously, it belongs to diet food, and effectively prevention of arterial is atherosis, and especially the content of cancer-resisting substance iodine, selenium is higher more than 20 times than other Ipomoea batatas.Therefore, the purple sweet potato in mountain, river is described as " space health food " in Japan, and the food as pilot, astronaut's indispensability has very big market potential and economic benefit.The drinamyl sweet potato is being of high nutritive value of potato meat not only, and young stem and leaf also is nutritious fresh vegetables.The data that provides according to Japan shows: the protein content of the climing tender point of the purple stem in mountain, river is higher more than 10 times than other vegetables such as water spinach, spinach, and the content of vitamin C, vitamin B2, calcium, iron, magnesium is higher than common vegetables.The Hebei Academy of Sciences is through chemical detection: the stem apex of mountain, river purple and piece root nutrient component all exceed the traditional category of China.Stem apex is fried, and with meat, the braised stir-fry of chicken or boil cold and dressed with saucely after boiling with boiling water, food flavor is better than fresh kidney beans, celery etc., in Hong Kong, the name of the dish on ground such as Guangzhou is long-life vegetable, day Sichuan cuisine, health care point etc.The purple sweet potato in mountain, river more and more causes extensive concern both domestic and external owing to have multiple actions such as nutrition, painted, health care.At home and abroad the sweet potato 4-6 that its price exceeds common variety on the market doubly.Existing sweet potato over wintering method, still continuing to use the traditional yam loaf root is preserved in the cellar survives the winter, the potato seed of will surviving the winter again after beginning of spring next year is taken out, plant in the smooth ground furrow of arrangement, harmony soil waters and urgees its germination, short its seedling of fertilising in good time comes into leaves luxuriant, when new talent is long when having 2 joint cauline leafs above, cut in good time be cut into into new seedling for transplanting use.There are the following problems for conventional method and survive the winter in such yam loaf root cellar: 1, over wintering is subjected to climatic influences and mashed potato occurs in unusual severe winter easily, even all rots, and the over wintering risk is higher; 2, expended a considerable number of the yam loaf root that can sell, the over wintering cost is bigger, and the drinamyl sweet potato of the purple kind in mountain, especially expensive river more makes the over wintering cost of drinamyl sweet potato quite big.This shows that it is lower to study a kind of over wintering process risk, it is necessary that the less drinamyl sweet potato of over wintering cost is planted seedling over wintering method.
Summary of the invention: the objective of the invention is to overcome the deficiency of prior art, a kind of over wintering process of research and design risk is lower, and the less drinamyl sweet potato of over wintering cost is planted seedling over wintering method.
The object of the present invention is achieved like this: a kind of drinamyl sweet potato is planted seedling over wintering method, it is characterized in that:
A, when gathering in the crops the drinamyl sweet potato in the fall, choose the stem rattan of sturdy no damage by disease and insect, cut off blade, cut the section of being cut into by every 2-3 joint, plant in the smooth ground furrow of arrangement, harmony soil waters, and short its survives;
B, survive after, when being lower than 10 ℃, planting ground and building the topped frame facility of double-layer plastic film on the furrow when ground temperature, when being lower than 0 ℃, increase again that one deck plastic foil is topped guarantees that the interior temperature of plastic foil frame facility is higher than 0 ℃ when ground temperature;
C, spring next year, when ground temperature more than 10 ℃ the time, one deck plastic foil that adds after throwing off impels to survive the winter and plants seedling and come into leaves from germinateing between the joint armpit to increase illumination;
D, when ground temperature more than 15 ℃ the time, throw off topped plastic foil, remove the frame facility, short its seedling of fertilising in good time comes into leaves luxuriant;
E, when new talent is long when having 2 joint cauline leafs above, cut in good time be cut into for the first batch of new seedlings that comprise at least 2 joint cauline leafs for transplanting use;
F, original surviving the winter are planted the suitable pruning of seedling except that behind the strong yellow blade, and its hyperplasia new talent is urged in fertilising in good time again, so that cut section second batch of new seedling.
Obtained following beneficial effect after the invention process:
1, reduced over wintering process risk effectively.Compare with the yam loaf root cellar conventional method of surviving the winter, it is less to be subjected to unusual severe winter climatic influences, and can observe in good time, adopts remedial measures, and avoids the failure of over wintering.
2, reduced the cost of over wintering effectively.Compare with the yam loaf root cellar conventional method of surviving the winter, need not expend the drinamyl yam loaf root of the purple kind in mountain, a considerable number of, expensive river fully, initial estimate has reduced the over wintering cost more than 80%.
