Selenium-enriched peach tree fertilizer and preparation method thereof

Abstract

The invention discloses a selenium-enriched peach tree fertilizer and a preparation method thereof, and belongs to the technical field of fruit tree fertilizer, wherein the selenium-enriched peach tree fertilizer is prepared from the following components in parts by weight: corncob, cottonseed hull, rice straw, potassium nitrate, ammonium nitrate, potassium dihydrogen phosphate, magnesium sulfate,calcium chloride, zinc sulfate, ferrous sulfate, inositol, glycine, carbendazim, potassium permanganate, tobacco shreds, selenium-enriched yeast, dextran and compound vitamins. The preparation methodincludes the following steps: (1) preparation of a mixture A; (2) preparation of a mixture B; (3) activation treatment; (4) sterilization treatment; and (5) drying treatment. The finally prepared selenium-enriched peach tree fertilizer cannot only prevent and cure bacterial shot hole of peach trees, but also can loosen soil, increase soil permeability, prevent the breeding of soil pathogens, promote healthy and strong growth of the peach trees, and balance nutrient components; selenium-enriched peach fruits easy to absorb are produced, the bioavailability is high, and the fertilizer has goodstability and long validity period, and has good market promotion value.

Description

Technical field [0001] The invention belongs to the technical field of fruit tree fertilizers, and specifically relates to a selenium-enriched peach tree fertilizer and a preparation method. Background technique [0002] The peach tree is a small deciduous tree whose fruit is used as a fruit. The flowers can be viewed and the fruit is juicy. The gum secreted from the peach tree trunk, commonly known as peach gum, can be used as a bonding agent. It is a glycan substance that can be hydrolyzed to generate arabinose, galactose, xylose, rhamnose, glucuronic acid, etc. It is edible, but also for medicinal purposes. Peaches are known as "Shou Tao" and "Xian Tao". Because of their delicious meat, they are also called "the first fruit in the world". Peach meat contains protein, fat, carbohydrates, crude fiber, calcium, phosphorus, iron, carotene, vitamin B1, and organic acids, sugars and volatile oils. It is suitable for patients with hypokalemia and iron deficiency anemia. [0003] Sel...

Problems solved by technology

[0004] In recent years, people have been taking selenium-containing medicines or health care products to supplement the selenium needed by the human body. However, medicines and health care products are generally expensive, and the real and fake are hard to distinguish. The effect of selenium supplementation is not very satisfactory. Adding selenium to food Among them, selenium is supplemented while supplementing nutrition. Selenium-enriched peaches fully enrich selenium into peach fruits through biotransformation of peach trees, which is convenient for human consumption and absorption

However, in recent years, bacterial perforation of peaches has been rampant, which not only harms leaves and new shoots, but also hinders the normal development of peach fruits, affects the enrichment of nutrients, including selenium, and seriously reduces the quality of peach fruits.

[0005] At present, most peach tree fertilizers are added with sodium selenite to obtain selenium-enriched peach fruits, but sodium selenite is highly toxic, has a narrow safety range, and low bioavailability. To obtain selenium-enriched peach fruits, most of the existing peach tree fertilizers are mixed with nutrient element compounds in the basic matrix and then sold in bags. The fertilizer itself has high humidity and is prone to breed a lot of bacteria. In severe cases, it will breed bacteria and cause peach trees Fertilization brought them pathogenic bacteria at the same time, not only did not promote the growth of peach trees, but hindered their normal development
