Abstract

The invention discloses a rich-selenium Chinese chestnut and a production method thereof, and solves the problems that the selenium content of a common Chinese chestnut cannot meet the needs of a human body, the selenium content in soil selenium application and punching for selenium injection is difficult to control, and the like. The method is characterized by comprising the following steps: uniformly spraying a selenium solution to the leaf surfaces of the plant in sunny day during each growth development period after the leafing of Chinese chestnut and before the coloring of fruit, particularly during the last period of pollination, expansion period and fruit strengthening period, wherein the selenium solution is sprayed once in each period, 3-6 times of spraying is performed at an interval of 15-30 days, and 4-10 g of selenium solution is sprayed onto the leaf surfaces of each mu so as to obtain a standard rich-selenium Chinese chestnut, wherein each kg of the standard rich-selenium Chinese chestnuts contains 100-500 micrograms of selenium. The production method is simple to dose, convenient to operate and the like; and other nutrient elements needed by the Chinese chestnut can be mixed with pest control medicines so as to improve the medicine effect and fertilizer efficiency; and the medicine is prepared by fruit growers when necessary, and is easy to popularize and use.

Description

Rich selenium Chinese chestnut and production method thereof

One, technical field

The invention belongs to plant cover cultivation methods, relate in particular to a kind of rich selenium Chinese chestnut and production method thereof.

Two, background technology

Chinese and foreign department scholar, medical worker are through semicentennial exploration, research, scientifically proved: each vitals of human body, comprise: heart, liver, kidney, pancreas etc. all need a certain amount of selenium to keep normal function, and the mankind have more than 40 kind of disease relevant with scarce selenium.As hepatopathy, tumour, cardiovascular, diabetes, cataract etc., particularly selenium and mankind aging's problem are closely related.

The World Health Organization in 1973 announces that selenium is the micronutrient of needed by human, Chinese Soclety of Nutrition selenium has been classified as 15 kinds every day one of diet nutrient, the suggestion per day for adults is taken in 50～250 microgram selenium.U.S. scientist points out: 21 century selenium will become one of main means anticancer and the multiple disease of prevention.

There is 72% territory shortage selenium element in China.The earth surface major part is poor selenium water and soil, causes most Se contents in the human foods can not satisfy the needs of human body.Total diet structure investigation that China carries out early 1990s, the result shows that selenium intake mean value is lower than the suitable intake lower limit 50 microgram/skies of selenium that Chinese Soclety of Nutrition is recommended in China resident diet.Therefore, the exploitation Se-rich farm products improves selenium intake by diet, has great importance for improving the general level of the health that lacks selenium resident colony.

At present, seen that document has that selenium is executed in soil spraying selenium, the punching transfusion of tree body, prescription production contains the selenium foliar compound fertilizer and executes selenium, to improve the selenium content of agricultural product, it is generally relatively more expensive to contain the selenium product.Waste and the environmental pollution of adopting the unavoidable adsorption by soil of soil spraying selenium and the aqueous solution to run off and cause; The tired lock of punching transfusion operation, workload is big; Containing the selenium composite fertilizer foliage fertilizer but is the polynary product that have fixed mixing ratio, under Protean different regions, different soils, different weather, Different Crop, different phenological natural conditions such as (vegetative period), each composition can't be supplied as required in accordance with its deal of principle of " wooden barrel law " rational application of fertilizers, causes exceeding standard or deficiency of certain composition easily.The rich selenium Chinese chestnut or other Se-rich farm products that adopt said method to produce, some selenium content are only slightly high than mill run, do not reach the selenium content standard, are difficult to control the selenium content of product.

Three, summary of the invention

Purpose of the present invention just provides a cover and reduces the work input as much as possible, production cost is dropped to bottom line, supportingly to greatest extent provide Chinese chestnut to produce required various nutriments, strengthen the resistance of plant, increase output, improve quality, and selenium content can be controlled at effectively the production technology the most easily of the rich selenium Chinese chestnut of cultivation in the GB standard allowed band.

Technical scheme of the present invention is: according to the common included soil cultivation of traditional Chinese chestnut culture technique, grafting, pruning, fertilising, gather, the diligent cultivated spy of a series of plantation operations such as storage, each growth and development stage before the fruit that extremely trembles behind Chinese chestnut exhibition leaf is painted, especially pollinate latter stage, expanding stage and strong fruit phase, select the fine plant leaf blade positive and negative of giving evenly to spray selenium solution, each issue spray once, 15～30 days at interval, spray altogether 3～6 times, the selenium solution that is sprayed is an agroatomizer container of 1～3 gram selenium (Se) (Se content 41～45% sodium selenate or sodium selenite white powder) being put into 14～18 liters, inject clear water then to full scale, be stirred to dissolving fully, each every barrel sprays about one mu on Chinese chestnut blade face, and average every mu of foliage spray 4～10 gram selenium solutions can obtain the rich selenium Chinese chestnut of standard of per kilogram selenium content 100～500 micrograms.

The invention has the beneficial effects as follows: not only batching simple, be convenient to operation, and can be equipped with Chinese chestnut required other nutritive element and pest control chemicals and use with, with raising drug effect and fertilizer efficiency, the orchard worker is now with the current, is easy to apply.Also have following effect simultaneously:

1, can improve that plant is cold-resistant, resistance such as drought resisting, disease-resistant, pest-resistant, heat resistanceheat resistant wind, to the inertia cell of old sick and wounded strain in can the activated plant body, repair impaired gene, improve circulation canal, activated immune system, the softness on maintenance organization, epidermis, blade face, keep light green, prolong the life-span of plant.According to " wooden barrel law ", use with mutually with other agricultural chemicals when it, be exactly the synergist of agricultural chemicals, it is used with mutually with other fertilizer, is exactly the synergist of fertilizer; Can urge to take root, inspire bud, urge to bloom, urge to increase fruit, short weightening finish, improve quality of agricultural product.The rich selenium Chinese chestnut that the present invention produces is compared with common Chinese chestnut, and labour and means of production cost can reduce more than 20%, increases production and improves the overall economic efficiency that quality produces and can improve more than 30%.

2, the rich selenium Chinese chestnut selenium content of the present invention's production is controlled in the suitable human body absorption requirement sanitary index scope, can not have side effects to human health.The natural organic selenium that is rich in has very strong oxidation resistance, can suppress the generation of lipid peroxide, in the energy and decompose carcinogenic substances, is the anticancer king in the trace element.Can remove free radical and cholesterol in the body, part toxic heavy metal such as cadmium, lead etc. are had natural detoxication and toxicant eliminating function effect.The injury of radioactive ray, microwave can be alleviated, the hectic fever, fidgety of Menopause can be treated human body.Inertia cell that can human activin is repaired impaired gene, improves circulation canal, and activated immune system is kept the softness of artificial skin, skin maintenance.Can reduce by more than 40 kind of disease incidence rate, people are promoted longevity.Have protect heart and brain, protect the liver kidney, anti-canceration, recover pancreas islet, effect such as delay senility.
