Cultivation method of organic selenium-enriched mulberry

Abstract

The invention belongs to the fruit tree cultivation field and particularly relates to a cultivation method of organic selenium-enriched mulberry. The cultivation method of the selenium-enriched mulberry comprises applying nano selenium fertilizer in different growing periods of mulberry trees, wherein the fertilizer applying periods can be divided into three phases of phase one, applying the nano selenium fertilizer to the mulberry trees at 30-50 grams per tree in the growing period of the mulberry trees in March; phase two, applying the nano selenium fertilizer to the mulberry trees at 50-60 grams per tree in late April; phase tree, after mulberry harvest, applying the nano selenium fertilizer to the mulberry trees at 50-60 grams per tree in the periods from early June to late August and from late August to early October. According to the cultivation method of the organic selenium-enriched mulberry, by applying the nano selenium fertilizer in different growing periods of the mulberry trees, most of harvested mulberry products have a selenium content of between 28.85 micrograms per hundred grams and 48.74 micrograms per hundred grams and the ratio of organic selenium is more than 80%.

Description

technical field [0001] The invention belongs to the field of fruit tree cultivation, and more specifically relates to a method for cultivating organic selenium-enriched mulberries. Background technique [0002] Selenium, as one of the currently known 14 essential micronutrients for the human body, is an antioxidant in the human body, can improve human immunity, and has various biological functions such as anti-cancer, anti-aging, improving sub-health status, and improving male fertility. Function is crucial to human health. [0003] 72% of my country's areas are in selenium-deficient and low-selenium ecological environment, and about 1 / 3 of them are seriously selenium-deficient areas, and more than 300 million people live in these areas for a long time. However, the price of pharmaceutical selenium supplements is expensive, and inorganic selenium is not easy to be absorbed by the human body. Once the storage of selenium supplementation is stopped, the nutritional status of ...

Problems solved by technology

On the one hand, there are already some natural selenium-enriched mulberry products on the market, such as natural selenium-enriched fresh mulberries in the picking garden, processed selenium-enriched mulberry wine and selenium-enriched mulberry drinks, etc., which have been favored by consumers. Love is enough to show that the market prospect is broad; on the other hand, studies have confirmed that natural selenium-enriched mulberry has become an ideal selenium supplement resource, which is far from satisfying people's desire and requirements for selenium supplementation

First, the selenium content is relatively low. Second, because the selenium-rich soil in selenium-rich areas is mostly in the shape of a chicken coop, one end of a piece of land is rich in selenium, and the other end is not rich in selenium, so the quality cannot be guaranteed.

Third, most areas in my country are selenium-deficient areas, and the output of selenium-enriched mulberries cannot meet

Natural selenium-enriched mulberries have defects such as low selenium content, unbalanced quality, and low yield. The main way for mulberry leaves to be enriched in selenium is to obtain selenium from the soil through root absorption. Selenium-enriched capabilities vary, mainly due to the genetic The influence of characteristics, soil selenium environment and climate conditions in the growth area, growth period and mulberry garden management, etc.
