Nutrient special for honey peach rich in organic selenium and application thereof

Abstract

The invention provides a nutrient special for honey peaches rich in organic selenium, which is prepared by evenly mixing 3-6 percent of nano-selenium plant nutrient, 1-2 percent of organic potash fertilizer and 0.2-0.6 percent of microbial fertilizer in percentage by weight. The invention also provides a method for producing the honey peaches rich in organic selenium, which comprises the steps ofapplying the nutrient special for the honey peaches rich in organic selenium for fertilizing at the dosage of 45-120g of selenium per mu according to a ridge fertilization method during anthesis or leaf growing period of peach trees; casually checking the selenium content of honey peach fruits when the honey peaches are ripe; and harvesting honey peaches with selenium content of 20-45mug / kg. Honey peaches produced by the method have higher safety and selenium in the honey peaches is more easily to be absorbed and utilized by human bodies.

Description

technical field [0001] The invention relates to a special nutrient for peaches rich in organic selenium and a method for producing peaches rich in organic selenium by using the special nutrient for peaches rich in organic selenium. Background technique [0002] Peach is a small deciduous tree whose fruit is used as a fruit. The flowers can be viewed and admired, and the fruit is juicy. It can be eaten raw or made into preserved peaches, canned food, etc. The kernels are also edible. Peach fruit is delicious and nutritious, and is one of the most popular fresh fruits. In addition to eating fresh, it can also be processed into preserved peaches, peach jam, peach juice, dried peaches and canned peaches. Many parts of the peach tree also have medicinal value. Its roots, leaves, flowers, and kernels can be used as medicine. It has the functions of relieving cough, promoting blood circulation, and laxative. The oil content of peach kernels is 45%, which can be used to extract ind...

Problems solved by technology

[0004] At present, there are two main methods for the production of selenium-enriched peaches in China. One is to spray selenite solution on peach flowers and peach tree leaves or to inject selenite solution into the trunk to improve the selenium content in peaches. The residual amount is large, because inorganic selenium must be combined with organic ligands in the intestinal tract before it can be absorbed and utilized by the body, and there are many elements in the intestinal tract that compete with selenium for limited ligands, which greatly affects the absorption of inorganic selenium

In addition, inorganic selenium has obvious toxic effects on organisms, and its safety is low.

The second is to plant peach varieties with strong selenium enrichment ability in natural selenium-rich areas. This method is difficult to quantitatively control the selenium content, has regional limitations, and is not conducive to large-scale standardized production
