Abstract
The invention discloses a cultivation method of konjac rich in selenium, zinc and calcium. According to the method, a konjac tuber is soaked in a selenium fertilizer diluent for 2-4 h, taken out, drained and planted, and 25-150 kg of quicklime is applied per mu according to the status of the pH of soil; a selenium fertilizer and a zinc fertilizer are mixed into a base fertilizer during base fertilizer application; 10-50 g of the selenium fertilizer is added with water per mu to pour the root for additional fertilization; and the selenium fertilizer diluent, a zinc fertilizer diluent and a calcium fertilizer diluent are used for 2-6 times of foliage spraying in a konjac growing period. According to the konjac cultivated by the method, the content of selenium, zinc and calcium in the konjac is further increased, nutrition and health care value of the konjac are enriched, and human health can be enhanced.
Description
Technical field
The present invention relates to konjaku cultivation, specifically the cultivation method of the rich selenium in acid red soil of south China area, rich zinc, rich calcium konjaku.
Background technology
Konjaku has the multiple functions such as lipopenicillinase, hypoglycemic, anti-cancer defaecation, the glucomannan that konjaku contains is a kind of macromolecular compound, has very strong water imbibition, and after water suction, the inflatable 80-100 of volume doubly, and can adsorb cholesterol and bile acid, to reducing blood pressure, reducing cardiovascular disease outbreak has certain effectiveness.Through online retrieval, the research to konjaku culture technique, mainly biases toward high-yield cultivating at present, and the research for other nutritive and health protection components in further raising konjaku, there is not yet report.
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, rich calcium konjaku, is worth further to improve the nutrition and health care of konjaku.
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, rich calcium konjaku, comprises the steps:
(1) selenium seed soaking: with the fertile dilution of 10000-15000 selenium doubly immersion konjaku stem tuber 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: the calcareous fertilisers dilution that the zinc fertilizer dilution that is 0.3-0.5% by the fertile dilution of dilution 10000-15000 selenium doubly, concentration and concentration are 0.5-1%, at konjaku foliar spray 2-6 time in vegetative period.
Step (5) is described execute foliage fertilizer be each spray of Seedling Stage, vigorous period and fruit expanding period at konjaku once.
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 rich selenium, rich zinc, rich calcium, cultivate, can greatly improve Organic Selenium, zinc, calcium content in konjaku, after measured, in konjaku, 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, and the konjaku obtaining by the rich selenium of the present invention, rich zinc, the cultivation of rich calcium cultivation method, has further increased the selenium in konjaku, zinc, calcium content, the nutrition and health care that has improved widely konjaku is worth, and has promoted health.
