Abstract
The invention discloses a method for cultivating selenium-rich, zinc-rich, calcium-rich purple potatoes. The method comprises the following steps: soaking tubers in selenium diluents for 2-4 hours, and taking out and draining off the tubers for planting; according to the condition of soil pH, applying 25-150kg of quick lime to soil per mu; during applying a base fertilizer, mixing a selenium fertilizer and a zinc fertilizer in the base fertilizer; then, adding 10-50g of the selenium fertilizer into water to spray roots for topdressing per mu; atomizing selenium fertilizer diluents, zinc fertilizer diluents and calcium fertilizer diluents on leaf surfaces within the growth period of purple potatoes for 2-6 times. The method cultivates the purple potatoes in a selenium-rich, zinc-rich and calcium-rich mode, so that the contents of selenium, zinc and calcium in the purple potatoes are further increased, the nutrition and health care values of the purple potatoes are enriched, and the body health can be improved.
Description
Technical field
The present invention relates to purple potato cultivation, specifically the cultivation method of the rich selenium in acid red soil of south China area, rich zinc, the purple potato of rich calcium.
Background technology
Purple potato is again black potato, and potato meat is purple to darkviolet.It,, except having the nutrient component of common Ipomoea batatas, is also rich in selenium element and anthocyan.Research to purple potato culture technique, mainly biases toward high-yield cultivating at present, and for the research of other nutritive and health protection components in the purple potato of further raising, report also seldom.
Summary of the invention
The cultivation method that the object of this invention is to provide the rich selenium in a kind of acid red soil of south China area, rich zinc, the purple potato of rich calcium, is worth further to improve the nutrition and health care of purple potato.
The technical scheme that realizes the object of the invention is:
The cultivation method of the rich selenium in acid red soil of south China area, rich zinc, the purple potato of rich calcium, comprises the steps:
(1) selenium seed soaking: with the fertile dilution seed soaking of 10000-15000 selenium doubly 2-4 hour, take out and drain plantation;
(2) execute quicklime: according to the situation of soil pH value, execute quicklime 25-150kg for every mu;
(3) basal dressing: sneak into selenium fertilizer and zinc fertilizer in base manure, materials proportioning is: Ji Fei ︰ Xi Fei ︰ zinc fertilizer=1000 ︰ 1 ︰ 5;
(4) spraying fertilizer: every mu with the fertile 10-50g of selenium, is watered pouring root;
(5) execute foliage fertilizer: with the fertile dilution of dilution 10000-15000 selenium doubly and concentration, be the calcareous fertilisers dilution that 0.3-0.5% zinc fertilizer dilution and concentration are 0.5-1%, at purple potato foliar spray 2-6 time in vegetative period.
The described spray foliage fertilizer of step (5) is that Seedling Stage, the potato piece at purple potato forms the phase, potato piece expanding stage respectively sprays twice.
Described selenium fertilizer is that the commodity selenium such as agricultural selenium fertilizer, sodium selenite, the rich treasured of selenium, selenium-rich amino acid foliage fertilizer are fertile.
Described zinc fertilizer is the commodity zinc fertilizers such as agricultural zinc fertilizer, zinc sulphate, zinc foliage fertilizer.
Described calcareous fertilisers are the foliage fertilizers such as agricultural lime, nitrate of lime, calcium chloride, calcium carbonate, calcium oxide, ionized calcium.
By the rich calcium of the rich zinc of rich selenium, cultivate, can greatly improve Organic Selenium, zinc, calcium content in purple potato, after measured, in purple potato, contain selenium 0.05-5mg/kg, zinc 100-500mg/kg, calcium 200-1000mg/kg.
Advantage of the present invention is: selenium is the trace element of needed by human, anti-oxidant, anti-ageing, anti-virus ability that tool is very strong, and the serious selenium that lacks in the food chain of China; Zinc can promote that human body grows, and strengthens body immunity, and the several functions such as whet the appetite; Calcium is to form the maximum element of human body, children's calcium deficiency can cause depauperation, feeblemindedness, adult's calcium deficiency can cause muscle cramp to be knotted, the elderly's calcium deficiency can cause osteoporosis, by the rich calcium of the rich zinc of the rich selenium of the present invention, cultivates purple potato, has further increased selenium, zinc, calcium content in purple potato, the nutrition and health care that has improved widely purple potato is worth, and has promoted health.
