Description
Technical field
The present invention relates to proportion of crop planting field.It is more particularly related to a kind of high-yield planting of selenium-rich drought Rhizoma Nelumbinis
Method.
Background technology
Non-irrigated Rhizoma Nelumbinis, also known as banana dasheen, queensland arrowrood etc., it is the plant of Lowiaceae Canna generalis Bailey category, the ground such as South America are originated in, on
Middle of century introduces China's cultivation.Non-irrigated Rhizoma Nelumbinis have become the new raw material sources of high value starch, dry lotus root starch particle in Asia
Footpath is big, and gelatinization point is low, and paste transparency is good, and chain content of starch is high, good film-forming property, and its molecular weight is also very big, with potato starch
It is close to, with preferable application feature.The exploitation of non-irrigated Rhizoma Nelumbinis to produce based on starch, and develop starch deep processed product and
The food items such as vermicelli, bean noodles.Dry lotus root starch is also widely adopted in more areas, and general 2.5 kilograms of dry lotus root starch can give birth to
0.5 kilogram of monosodium glutamate is produced, the kind of starch such as oral and glucose for injection, Sorghum vulgare Pers. Maltose sugar can be also produced, and it is various for Amylum Nelumbinis Rhizomatis etc.
Non-staple food.In textile industry, dry lotus root starch sizing is used, than using foodstuff starch sizing, with caking ability is high, the spy such as fineness is good
Point.Dry lotus root starch can be additionally used in papermaking, shoemaking, hatting, clothing and cultural goods etc..
Selenium is trace element needed by human.Chinese Soclety of Nutrition also by selenium be classified as needed by human 15 kind nutrient it
One, a large amount of clinical experiment both at home and abroad are bright, and human body lacks selenium can cause the functional disorder of some vitals, cause many serious diseases
Occur, the country of the whole world more than 40 in lacking selenium area, several hundred million populations in Chinese 22 provinces all in scarce selenium or low selenium area,
The sickness rate such as these regional population tumor, hepatopathy, cardiovascular disease are very high.
At present the non-irrigated Rhizoma Nelumbinis of domestic plantation are mainly distributed on the ground such as Guangxi, Yunnan and Guizhou, with field, Around the house nature
Based on growth, due to lacking management, the yield of non-irrigated Rhizoma Nelumbinis is relatively low, and quality is also uneven.And the soil on the ground such as Guangxi, Yunnan and Guizhou
Se content is not high in earth, so the Se content of the crops in above-mentioned area is not also high.
The content of the invention
It is an object of the invention to provide non-irrigated Rhizoma Nelumbinis are carried out the farming pipe of science by a kind of high-yield planting method of selenium-rich drought Rhizoma Nelumbinis
Reason, selenium mineral powder and selenium-rich base fertilizer are applied in site preparation to plantation field, and apply Selenium-rich nutrient solution and fertilizer rich in selenium in planting process,
Not only yield is high but also rich in selenium element for the non-irrigated Rhizoma Nelumbinis tuber of results, with high nutritive value and economic worth.
In order to realize these purposes of the invention and further advantage, there is provided a kind of high-yield planting side of selenium-rich drought Rhizoma Nelumbinis
