Embodiment 1

[0032]Example 1 (spraying foliar fertilizer)

[0033]Foliar fertilizer components: diethyl aminoethyl hexanoate (calculated with ≥98% diethyl aminoethyl hexanoate) 4g, bamboo vinegar liquid (calculated with 100% bamboo vinegar liquid stock) 100ml, the density of the bamboo vinegar liquid is 1g / ml Calculate, nano-selenium (calculated as 100% pure nano-selenium) 1g, weigh the above components, mix and prepare 1000ml foliar fertilizer mother liquor, dilute with water 200 times to obtain the foliar fertilizer application liquid, In the fertilizer application liquid, the diethyl aminoethyl hexanoate content is 20mg / L, the bamboo vinegar content is 0.5g / L, and the nano-selenium content is 5mg / L.

[0034]Select a farmland in Liantang Town, Nanchang County, Jiangxi Province, take soil samples, and test the total selenium content according to NY / T1104-2006 "Determination of Total Selenium in Soil" method, and the result is 0.22mg / kg. Plant rice, pepper, Chinese cabbage is planted and field managed...

Abstract

The invention provides a crop foliar fertilizer. The crop foliar fertilizer is prepared from the following raw materials: diethyl aminoethyl hexanoate, bamboo vinegar and nano-selenium. The mass partratio of the diethyl aminoethyl hexanoate to the bamboo vinegar to the nano-selenium is (1-10):100:(0.5-5). The crop foliar fertilizer has the following advantages that the selenium-enriched foliar fertilizer is prepared by taking nano-selenium as a selenium source, bamboo vinegar as a selenium chelating agent and diethyl aminoethyl hexanoate as a regulator, and the crop yield and the selenium content in crop organs can be effectively improved. The foliar fertilizer is simple in application method, simple and convenient to operate and good in effect. Besides, the foliar fertilizer has no toxicor side effect on plants, animals and human bodies, has no adverse effect on normal growth and development of rice, and is low in price, mild in method and free of toxic or side effect.

Description

Technical field[0001]The invention relates to the field of crop research, in particular to a crop selenium-enriched foliar fertilizer and its application.Background technique[0002]Selenium is an essential trace element for humans and animals, as well as an important component to maintain enzyme activity, and participates in important physiological processes of immunity and anti-cancer. Studies have found that many diseases of the human body are related to selenium deficiency, such as anemia, cancer, hepatitis, etc. Therefore, intake of appropriate amounts of selenium is very necessary to maintain human health. From a global perspective, soil selenium deficiency is very common. About 72% of cities and counties in China are severely selenium-deficient or low in selenium. People in selenium-deficient areas eating selenium-enriched agricultural products is the most economical, effective, safe and convenient way to supplement selenium.[0003]Therefore, people have a great demand for selen...
