Selenium-rich foliar fertilizer and preparation method and application thereof

Abstract

The invention relates to a selenium-rich foliar fertilizer and a preparation method and application thereof. The selenium-rich foliar fertilizer is prepared from the following components in part by weight: 25 to 35 parts of castor oil polyoxyethylene ether, 6.25 to 12.5 parts of 2a,3a,22s-tetrahydroxyRethyl-beta-homo-7-oxa-5a-cholest-6-ketone 0.10 percent powder, 2.9 to 3.6 parts of sodium selenite, 52.5 to 55 parts of glutamic acid, 25 to 30 parts of ethanol, 0.1 to 0.15 part of caramel pigment, 25 to 27.5 parts of carbamide, 12.5 to 15 parts of boric acid and the balance of water. The selenium-rich foliar fertilizer has an economic formula, lasting functions, and obvious selenium enriching effect, yield increasing effect and visual effect after being applied to crops. The preparation method is the conventional mixing and stirring method. The process is simple, and a small number of devices are used. The selenium-rich foliar fertilizer is diluted by water in an amount which is 150 to 200 times that of the fertilizer and is directly sprayed on the leaf surfaces of plants. The selenium-rich foliar fertilizer is simply applied and has high applicability.

Description

technical field [0001] The present invention relates to a foliage fertilizer, more specifically, the invention relates to a selenium-enriched foliage fertilizer, and at the same time, the invention also relates to a preparation method and application of the selenium-enriched foliage fertilizer. Background technique [0002] There is a selenium-deficient belt from northeast to southwest in my country. 72% of the country is selenium-deficient, and about 700 million people live in a low-selenium environment. Selenium deficiency can cause more than 40 diseases such as Keshan disease, Kaschin-Beck disease, cancer, cardiovascular and cerebrovascular diseases, cataracts, hypertension, diabetes, male infertility, cystic fibrosis, and human aging. [0003] To this end: in December 2004, CCTV's "Sunset Red" column specially produced a special program "Selenium Supplementation for Anti-cancer and Anti-aging"; on January 8, 2005, the "Disease Prevention and Treatment, Quantitative Sele...

Problems solved by technology

[0014] The selenium-enriched yield-increasing agent developed by the Heilongjiang Academy of Agricultural Sciences has both selenium-enriching and yield-increasing effects, but the yield-increasing effect is poor, and the average yield per mu is only 12kg;

[0015] Harbin Institute of Technology and others have developed selenium-enriched foliar fertilizers for rice and conducted experiments on the effects of selenium-enrichment and yield-increasing effects on rice. They have achieved both significant selenium-enrich
