Description
Technical field
The present invention relates to technical field of economic crop cultivation, specifically a kind of implantation methods of selenium-rich Chinese yam.
Background technology
Selenium is one of indispensable trace element of human life, and medical information is shown, selenium is some in animal and human body
The important component of antioxidase and selenium-P albumen, play a part of balance oxidation reduction in vivo, selenium is to a variety of of the mankind
Disease plays the role of prevention and auxiliary treatment, and it can strengthen the immunologic function of human body, and has the function that anti-cancer, anticancer, right
Diabetes, Kaschin-Beck disease, asthma, parkinsonism, cardiovascular and cerebrovascular disease etc. can also play good preventive and therapeutic action, selenium deficiency
It may further result in the generation of various eye illnesses.Selenium-supply is the measure of the best preventive cancer, but selenium is directly taken and is not easy by human body
Absorbed, best selenium-supply measure is that the purpose that selenium reaches selenium-supply is absorbed from food.
Chinese yam, also known as Chinese yam, wherein containing materials such as amylase, polyphenol oxidase, be advantageous to taste digestion and absorption function,
It is the product of the medicine-food two-purpose of flat tonifying spleen and stomach simply.And contain various nutrients, there are strong body, the effect of nourishing kidney and replenishing pneuma.Mesh
The preceding research to Chinese yam cultivation technique, mainly bias toward high-yield cultivating, for further improve Chinese yam in other nutrition and health cares into
The research divided, report are also seldom.
Guangxi Guigang Guiping City is one of district rich in selenium in Guangxi having found, belongs to high-quality natural selenium-rich area, 70% with
On soil basically reach the standard of selenium-rich soil（0.4 more than mg/kg）, some are up to 2.91mg/kg, and major part exists
0.7mg/kg or so, great Development volue.Guiping is also Chinese yam major production areas simultaneously, and cultivation history is long, widely distributed.With
Industry restructuring and the development of market economy, the production of Guiping City Chinese yam are developed rapidly, occupied in agricultural planting structure important
Status.Develop Chinese yam production has turned into growth of agricultural efficiency, one of the important channel of increasing peasant income.In recent years, Guiping City creates energetically
Se-rich farm products base, Se-rich farm products are developed, at present, build together into Se-rich farm products production base 8, area is up to more than 3200
Mu, and how using geographical environment advantage the high selenium-rich Chinese yam high-yield culturing of health-care effect is realized, tool is of great significance.
The content of the invention
For above technological deficiency, it is an object of the invention to provide a kind of implantation methods of selenium-rich Chinese yam, select selenium-rich
Area plantation, and in Chinese yam growth and development process, foliage-spray selenium-rich solution, by the biochemical reactions of Chinese yam itself,
The Organic Selenium that inorganic selenium suction people's plant conversion in the body behaviour physical efficiency is absorbed, is enriched in Chinese yam stem tuber and reaches selenium-rich standard
As selenium-rich Chinese yam.
Technical scheme is as follows：
A kind of implantation methods of selenium-rich Chinese yam, it is characterised in that comprise the following steps：
（1）Bulbil is bred：The bulbil sand storage that last year harvests is passed the winter, is seeded in Second Year spring in seedbed, seeding row spacing
10cm square, summer seedling, autumn form potato seed；
（2）Transplanting in good time：In late March to late April, Se content is selected when seedling grows to 30cm more than 0.4 mg/kg's
Soil carries out ditching transplanting, and distance between rows and hills is 60~70cm × 25~30cm, and per hectare plants 52500~67500 plants, furrow width 30cm,
Deep 20cm, the deep mellow soil of 20cm is placed on ditch both sides, then proceedes to 30~40cm of lower digging, soil scarifying is whole broken, by base manure with turning over
After soil after pine fully mixes, then mellow soil is put into ditch, is made into wide 30~35cm, high 20cm ridge, then Chinese yam seedling
Field planting pours root water on ridge；
（3）Field management：After height of seedling 35cm, timely built, it is barricaded as A-frame or vertical type shelf with 1.5~1.8m bamboo pole, makes
Vines winding is grown up；
（4）Timely top dressing：Growth period top dressing 3~4 times；First time top dressing is carried out when taking out climing；Carried out as height of seedling 50cm second
Top dressing；Third and fourth top dressing is carried out in bud stage, knot potato phase；
（5）Spindling control：In initial bloom stage, sprayed 1 time with 15% paclobutrazol wettable powder, 1000~1500 times of liquid, growth is vigorous
After 7 days, then spray 1 time；Spraying 2-3 times with 0.3% potassium dihydrogen phosphate at later stages prevents early ageing；
（6）Insect pest preventing and controlling：With 58% metalaxyl manganese-zinc wettable powder, 500 times of liquid, the more Mil's wettable powders 800 of 25% thunder~
1000 times of liquid, 80% anthrax good fortune U.S. 800 times of liquid of wettable powder, 70% thiophanate methyl wettable powder, 1500 times of liquid spray anti-
Control, continuous 2~3 times, every 7~10 days 1 time；
（7）Selenium-rich mechanism：21 ~ 25g is preserved with grain and oil type zinc selenium, 5 ~ 8mL of Jia Buneite, adds 15 ~ 20kg of water, stirs；
20 ~ 25cm of height of seedling applies selenium 1 time before not transplanting, per hectare applies selenium solution 225kg；In squaring period, florescence, tuber expansion period difference
Apply selenium 1 time, per hectare applies selenium solution 450kg, and leave dual sides are sprayed.
Specifically, step（4）Described in first time top dressing：From plant base portion 30cm, deep wide 8~10cm ditch is excavated, will
Fertilizer is applied in ditch, and per hectare applies 12000~15000kg of people and animals' liquid dung；Second of top dressing：Per hectare applies people and animals' liquid dung
12000~18000kg, and earth up 1~2 time；Described 3rd, the 4th top dressing：Per hectare apply people and animals' liquid dung 22500~
30000kg, and cover ground cooling moisture-retaining with green grass or cogongrass.
Specifically, the step（2）Described in base manure be：Per hectare applies 30000~45000kg of decomposed manure, carbon ammonia
420 ~ 450kg, 350 ~ 375kg of potassium sulfate.
Specifically, Chinese yam can carry out intercropping and interplanting with solanaceous vegetables, Kidney bean, radish, spinach, muskmelon, seeding corn and other crops.
The beneficial effect of the invention is：
1st, the present invention carries out bulbil generative propagation using to Chinese yam, kind of property can be kept constant, compared to vegetative propagation, its line of breeding
Number is higher, it is not easy to degenerates；By suppressing Chinese yam tendril excessive growth, the organic matter and potato wedge Root Absorption that synthesize photosynthesis
Nutrition is mainly used in the growth of Chinese yam potato wedge, greatly improves yield；The plantation of selenium-rich soil is selected, ensure that in the whole of Chinese yam growth
The selenium that process has abundance is available for absorbing, and saves the selenizing fertilizer for needing to put into；In Chinese yam growth and development process, foliage-spray
Selenium-rich solution, by the biochemical reactions of Chinese yam itself, inorganic selenium suction people's plant conversion in the body behaviour physical efficiency is absorbed
Organic Selenium, be enriched in Chinese yam stem tuber and reach selenium-rich standard and turn into selenium-rich Chinese yam.
