Production method of selenium-enriched chestnut

Abstract

The invention discloses a selenium-enriched Chinese chestnut production method and belongs to the technical field of Chinese chestnut planting. The selenium-enriched Chinese chestnut production methodcomprises the following steps that 1, a selenium-enriched nutritional solution A is delivered in a flowering period, wherein the selenium-enriched nutritional solution A is prepared from selenium mineral powder, fulvic acid, a potassium hydroxide solution, ammonium phosphate and potassium nitrate; 2, a selenium-enriched nutritional solution B is delivered in a fruit swelling period, wherein the selenium-enriched nutritional solution B is prepared from selenium mineral powder, potassium carbonate, sodium humate, selenized carrageenan, manganese sulfate, citric acid chelated iron, citric acid chelated copper and water. The selenium-enriched Chinese chestnut production method also comprises the steps of fruit processing after picking. Tree bodies directly absorb the selenium-enriched nutritional solutions in a nutritional solution delivery mode according to the characteristics of Chinese chestnuts, the selenium utilization rate can be improved, the selenium content in the Chinese chestnuts can be increased, the use amount of selenium fertilizers or the selenium-enriched nutritional solutions can be decreased, the cost can be reduced, the selenium content of Chinese chestnuts producedby adopting the method is high by cooperating with the selenium-enriched nutritional solutions for later Chinese chestnut fruits, and the daily selenium supplementing demand of people can be met.

Description

technical field [0001] The invention relates to the technical field of chestnut planting, in particular to a production method of selenium-enriched chestnuts. Background technique [0002] Chestnut, also known as chestnut, chestnut, and wind chestnut, is a plant of the Fagaceae chestnut genus. It grows in areas with an altitude of 370-2800 meters, is more common in mountainous areas, and has been widely cultivated artificially. Chestnuts are rich in nutrients, and their vitamin C content is higher than that of tomatoes, and more than ten times that of apples. The minerals in chestnuts are also very comprehensive, including potassium, zinc, iron, etc. Although the content is not as high as that of hazelnuts, it is still much higher than ordinary fruits such as apples, especially the potassium content is 3 times higher than that of apples. [0003] Selenium is an essential mineral nutrient for the human body, which cannot be synthesized in the human body. The total selenium c...

Problems solved by technology

[0005] The production method of selenium-enriched chestnut is generally to use selenium fertilizer as fertilizer and apply it to the soil. The chestnut tree absorbs selenium and transmits it to the chestnut fruit. This method will cause soil adsorption and fixation and water loss, thereby reducing the content of selenium absorbed by the chestnut tree. Just need to apply more selenium fertilizer, cost increases; Also have a kind of method commonly used to spray selenium-enriched foliar fertilizer on the foliage of chestnut tree exactly, this kind method evaporates easily after the selenium-enriched foliar fertilizer is sprayed, just The need to increase the amount of use will also increase the cost
