Cultivation method for selenium-rich and high-yield apples

Abstract

The invention discloses a cultivation method for selenium-rich and high-yield apples. The cultivation method comprises the following steps: step 1, preparation of a mixed fertilizer: a step of successively adding the following components in parts by weight into a high-speed pulverizer: 32 to 38 parts of farmyard manure, 12 to 16 parts of diatomite, 8 to 12 parts of zeolite powder, 6 to 10 parts offly ash, 5 to 7 parts of humic acid, 4 to 6 parts of alginic acid, 5 to 7 parts of ammonium hydrogen carbonate, 3 to 4 parts of ammonium hydrogen phosphate, 1 to 2 parts of glutamic acid, 1 to 2 parts of leucine and 1 to 2 parts of an iron source, carrying out pulverizing, then adding pulverized components into a high-speed stirrer, and carrying out stirring at a stirring speed of 500 to 600 r / min and a temperature of 30 to 40 DEG C for 3 to 4 hours. The cultivation method for the selenium-rich and high-yield apples provided by the invention has the advantages of high apple yield, rich selenium element in apples, good economic benefit, high use value and good application prospects.

Description

technical field [0001] The invention relates to the field of cultivation technology, in particular to a method for cultivating selenium-enriched and high-yield apples. Background technique [0002] Selenium is a relatively rare metalloid element. It was not listed as an essential trace element for the human body until the 1970s. Its required amount and poisoning amount are relatively close. Organic selenium compounds are less toxic than inorganic selenium compounds. Natural The content of selenium in food is very small, most of the current selenium products are various products containing organic selenium, selenium deficiency is an important cause of Keshan disease, selenium deficiency can induce liver necrosis, selenium deficiency can induce cardiovascular disease, human Mild or moderate selenium deficiency, the signs and symptoms are not obvious. At present, the acquisition of selenium is basically from the diet, and the selenium-enriched food naturally formed in the plant...

[0003] Chinese patent document "(Application No.: CN201310060992.2)" discloses a nutritionally enhanced selenium-enriched apple and its cultivation method. The nutrient solution composed of active water, osmotic agent, protective agent, buffering agent, emulsifier, etc. is used before apple tree germination, apple tree fruit setting period, mid-fruit period in early May and mid-July, and 20 days before fruit picking, Carry out 5 times of spraying to leaf surface respectively, spray the diluted selenium nutrient solution evenly on the apple branches and leaf surface with mechanical or artificial mist spraying, although the apples planted by this cultivation method contain selenium, but The content is not very high and needs to be further improved. In addition, the yield of apples planted is not very high
