Abstract

The invention discloses a preparation method of a selenium-enriched compound foliar fertilizer for millets and an application method thereof, belonging to the field of crop biotechnologies. The preparation method comprises the following steps of: soaking 2-3 parts of fulvic acid and 250-300 parts of water by weight, and filtering out solid residue to obtain a compound fertilizer mother liquid; and dissolving 0.25-0.5 kg of sodium selenite into 100 kg of mother liquid, uniformly agitating the solution so that no precipitate is left, and completely reacting to obtain the selenium-enriched compound foliar fertilizer. 1000 ml of selenium-enriched compound foliar fertilizer is applied to one mu of field, and the selenium-enriched compound foliar fertilizer is firstly diluted by 50 times and then sprayed. Millets produced by using the selenium-enriched compound foliar fertilizer conform to food safety standards and do not have toxic or side effects or drug residues, the market demands at present are satisfied, the diet structure of people is improved, and the selenium-enriched compound foliar fertilizer has important realistic meaning in improving people's living standards.

Description

technical field [0001] The invention relates to a preparation method of a selenium-enriched foliar fertilizer and an application method thereof, in particular to a preparation method of a millet selenium-enriched compound foliage fertilizer and an application method thereof. Background technique [0002] Millet, also known as millet, originated in the Yellow River Basin of my country. It is a cultivated species of Setaria (2n=2X=18, English name Foxtail millet, scientific name Setaria italica), and is one of the "five grains". Millet was the largest cultivated crop in the Neolithic Age, mainly distributed in China, accounting for about 80% of the world's total output; the caryopsis after shelling is millet, and its color is yellow, off-white, brown or black. Millet is one of the four major food crops in my country. It has a long cultivation history of more than 7,000 years and occupies an important position in the national food crops. Its characteristics of drought resistanc...
