Problems solved by technology

[0004] 1. The amount of glutamic acid and boric acid is relatively large, and the price of glutamic acid and boric acid is relatively high, so that the cost of the selenium-enriched foliar fertilizer is relatively high;
[0005] 2. After using 2a, 3a, 22s-tetrahydroxy R-ethyl-β-homo-7-oxa-5a-cholestan-6-one 0.10% powder (common trade name: brassinolide), the rich Selenium foliar fertilizer lacks obvious intuitive effects. After spraying, farmers cannot see or touch it, so it is difficult to believe in its fertilizer effect, and it is difficult to apply and promote it. It is difficult to gain a firm foothold in the market. Improve the effect of selenium enrichment;
[0006] 3. The concentration of the selenium-enriched foliar fertilizer is too high in terms of selenium, and the excessively high selenium content inhibits the growth of crops and reduces the yield of crops

Abstract

The invention relates to a selenium-rich foliar fertilizer, a preparation method and an application thereof. Per 500 parts by weight of the selenium-rich foliar fertilizer is prepared by mixing following components including, by weight, 25-35 parts of polyoxyethylene castor oil, 0.35-0.4 parts of 85% powder of gibberellins, 0.4-0.6 parts of sodium selenite, 10-14 parts of potassium dihydrogen phosphate, 25-30 parts of ethanol, 25-27.5 parts of carbamide, 0.4-0.6 parts of hydrochloric acid and the balance water. The selenium-rich foliar fertilizer is reasonable and economical in formula, is low in cost, is durable in effect and has a significant intuitive effect, a significant yield-increasing effect and a significant selenium-rich effect. The preparation method is a conventional mixing and stirring method which is simple in technology and less in required equipment. The application of the selenium-rich foliar fertilizer is that the selenium-rich foliar fertilizer is diluted by 150-250 time with water and is directly sprayed onto leaf surfaces of a plant. The selenium-rich foliar fertilizer is simple in application method and is strong in applicability.
