Problems solved by technology

[0005] At present, there are literatures that apply selenium to the soil, apply selenium to tree body perforation, and apply selenium-containing foliar compound fertilizer to increase the selenium content of agricultural products. Selenium-containing products are generally more expensive.
Applying selenium to the soil will inevitably lead to waste and environmental pollution caused by soil adsorption and aqueous solution loss; the perforated infusion method is cumbersome to operate and requires a lot of work; the selenium-containing compound fertilizer foliar fertilizer is a product with a fixed ratio of multiple elements, and in ever-changing conditions Under natural conditions such as different regions, different soils, different climates, different crops, and different phenological periods (growth periods), each ingredient cannot follow the principle of "barrel law" formula fertilization, and its portion is supplied on demand, which may easily cause a certain ingredient to exceed the standard or insufficient
Some selenium-enriched chestnuts or other selenium-enriched agricultural products produced by the above method have a slightly higher selenium content than ordinary products, which cannot meet the selenium content standard, and it is difficult to control the selenium content of the product

Embodiment 1

[0011] Embodiment 1: Add 1 gram of Se (sodium selenate or sodium selenite white powder) with 16 liters of knapsack (hand, electric or motor-driven) sprayer, pour clear water to the full scale of the bucket, stir and dissolve, choose sunny days on leaves Spray evenly on the front and back sides, and spray the leaf crown area of ​​about one mu per bucket of liquid, respectively on May 11 (initial flowering stage), May 25 (full flowering stage), June 10 (peak pollination stage), and August 6 Spray once each day (fruiting period), a total of four times, with an average of 4 grams of Se per mu. The mixed sample of fresh chestnuts was collected at the end of August for testing, and the content of selenium per kilogram of fresh chestnuts was 102.82 micrograms.

Embodiment 2

[0012] Embodiment 2: Add 1 gram of Se (sodium selenate or sodium selenite white powder) with 16 liters of knapsack (hand, electric or motor-driven) sprayer, pour clear water to the full scale of the bucket, stir and dissolve, choose sunny days on leaves Spray evenly on the front and back, and spray the leaf canopy area of ​​about one mu per bucket of liquid. Spray once each on August 3 (pericarp formation period) and August 3 (expansion period), a total of 5 times, with an average of 5 grams of Se per acre of leaf canopy area, and at the same time add Huokangzhuangfeng to each barrel according to the product instructions. (disease prevention), Chestnut Chestnut Clear (deworming). At the beginning of September, a mixed sample of mature and fresh chestnuts was taken for testing: the selenium content was 178 micrograms per kilogram.

Embodiment 3

[0013] Embodiment 3: Add 2 grams of Se (sodium selenate or sodium selenite white powder) with 16 liters of knapsack (hand, electric or motor-driven) sprayer, pour clear water to the full scale of the bucket, stir and dissolve, choose sunny days in the leaves Spray evenly on the front and back sides, and spray the canopy area of ​​about one mu per barrel of liquid. Use Se2 on June 17 (bud stage), July 18 (expansion stage), and August 7 (fruit stage) respectively. gram, each sprayed once, totally 3 times, the average per mu leaf canopy area uses Se6 gram, also adds urea, potassium dihydrogen phosphate, calcium treasure foliar fertilizer (boron zinc calcium, amino acid) at every turn by the commodity manual consumption simultaneously , The mixed sample of natural mature fresh chestnuts was taken during the harvest period in early September, and the selenium content was 340 micrograms per kilogram.

Abstract

The invention discloses a production method for a rich-selenium Chinese chestnut, which solves the problems that the selenium content of a common Chinese chestnut cannot meet the needs of a human body and the selenium content in soil selenium application and punching for selenium injection is difficult to control, and the like. The method is characterized by simply spraying the solution of sodium selenite or sodium selenate (Se) to the leaf surfaces of the plant, each kg of the standard rich-selenium Chinese chestnuts is stably and flexibly controlled to contain 100-500 micrograms of selenium, thereby conforming to the national standard on rich-selenium products. The method has the advantages of low cost, simple dosing, convenient operation and the like. 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. The medicine is prepared by fruit growers when necessary, and is easy to popularize and use. Each chestnut is marked with its selenium content, so that people different in supplement needs of selenium can check the acceptable daily intake of selenium to realize the nutritional supplement of selenium. Thus, the excessive or insufficient supplement of selenium is avoided. The selenium supplementing effect for people is ensured and the human health is promoted.

Description

1. Technical field [0001] The invention belongs to plant planting methods, in particular to a selenium-enriched chestnut and a production method thereof. 2. Background technology [0002] After half a century of exploration and research by Chinese and foreign scientists and medical workers, it has been scientifically demonstrated that various important organs of the human body, including: heart, liver, kidney, pancreas, etc., all need a certain amount of selenium to maintain normal functions. There are more than forty kinds of diseases related to selenium deficiency. Such as liver disease, tumor, cardiovascular, diabetes, cataract, etc., especially selenium is closely related to human aging problems. [0003] In 1973, the World Health Organization announced that selenium is an essential micronutrient for the human body. The Chinese Nutrition Society has listed selenium as one of the 15 daily dietary nutrients. It is recommended that adults consume 50-250 micrograms of selen...
