Description

The selenium-rich purple sweet potato planting technology
Technical field
The present invention relates to the proportion of crop planting technology, be specifically related to a kind of selenium-rich purple sweet potato planting technology.
Background technology
Purple sweet potato cries sweet potato, sweet potato, pachyrhizus again, originates in Central America, and in the optimum food list that the World Health Organization confirms, sweet potato is arranged in the umber one of best vegetables group.China introduced since 2002, because the color of sweet potato is pansy, so cry purple sweet potato, purple sweet potato contains abundant trace element, and as iron, phosphorus, calcium, zinc etc., especially the content of selenium is higher, the rhizome of sweet potato is vitamin " rich ore ", is again anticancer expert.Over nearly 20 years, it is abundant that external increasing result of study demonstrates the sweet potato nutritive value.Sweet potato is rich in 18 seed amino acids, and the content of dietary fiber is rice, face 10 times, and vitamin E is 9.5 times of wheat, is a kind of physiological basic food, keeps the required acid base equilibrium of health.The bright potato of its organic selenium content per kilogram reaches more than 0.01 milligram, and the bright potato of anthocyanidin content per kilogram reaches 200 milligrams, and often edible can playing improved immune, hypotensive, liver-protective health-care effect.But purple sweet potato plantation is subject to seasonal restrictions, and the cultivated area of domestic edible purple sweet potato is little at present, skewness, and supply falls short of demand in market.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of green, nuisanceless, edible healthy selenium-rich purple sweet potato planting technology.
Technical problem to be solved by this invention realizes by the following technical solutions,
The selenium-rich purple sweet potato planting technology is characterized in that: may further comprise the steps,
1, grows seedlings: when mid-February, temperature reached the 15 degree left and right sides, can go out the cellar for storing things and grow seedlings, carry out the seedbed earlier, the connection of seed traverse is come on the seedbed, about 5 centimeters of line spaces, cover fine earth, soil is squirted, build mulch film with sprayer, cover a day film, moisture-heat preservation to more than the bud seedling length to 20 centimeter the time, just can be cut and be inserted into big field;
2, ridging: the good soil environment of select dark, pine, living, the spring potato requires to plough deeply 25-35 centimetre in 15 days in advance, the big ridge of zanjon is for well, reach deep ploughing, native carefully, row spacing is generally at 60-70 centimetre, the high 25-30 in ridge centimetre; The disposable base manure that uses sufficient, general mu is executed high-quality fertilizer 40-50 load, and nitrogen, phosphorus, potassium, composite fertilizer 35-50 kilogram, fertilizer spread fertilizer over the fields before all ploughing, and make Bao Xinfei during the composite fertilizer ridging;
3, transplant: select the short shape seedling of first section or second section 19-24 centimetre in purple sweet potato to transplant, general spring potato is transplanted to well late April to May, and the potato seedling is with slotting being advisable crosswise, and the degree of depth is planted into three joints and is advisable, and it is many that internode is tied potato; Spacing is generally 18-22 centimetre, and insert about purple sweet potato seedling 4000 strains in every mu in the field of fertile soil, and every mu of the thin partially field piece of soil is about 4500 strains;
4, field management: it is moistening to do to take advantage of soil behind the ridge, play weed killer herbicide one time, prevents weed growth, intertills 2-3 time, in conjunction with the cultivation and banking support ridger, purple sweet potato is afraid of accumulated water, must in time get rid of, when arid is serious, with good conditionsily want timely drought resisting, in time propose Teng and prevention and elimination of disease and pests;
5, results storage: will gently dig during results, gently transport, put down gently, reject potato piece that is in spite of illness, insect bite, damaged, water logging, go into the cellar for storing things after 3-4 days in purple sweet potato storage ground airing, kiln temperature is controlled at 10 ℃-14 ℃, humidity is controlled at 80%-95%, when oxygen in the air and carbonic acid gas are respectively 15% and 5%, can suppress to breathe, reduce organic nutriment consumption, increase storage thief's time.
The invention has the beneficial effects as follows: the purple sweet potato output by the present invention's plantation is big, quality better, and the color and luster uniqueness, mouthfeel is fragrant and sweet, belong to green non-pollution food, be of high nutritive value, pass through storage technology, can realize the annual supply of purple sweet potato, equilibrium market meets the consumption concept of people to environmental health.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with specific embodiment, further set forth the present invention.
