Hole applied fertilizer special for tobacco and preparation method thereof

Abstract

The invention belongs to the technical field of fertilizer, and provides a hole applied fertilizer for tobacco and a preparation method thereof. The hole applied fertilizer for the tobacco is prepared from, by weight, 5-30 parts of potassium fulvic acid, 1-25 parts of amino acid, 0.01-2 parts of azadirachtin, 20-70 parts of ammonium nitrate, 10-40 parts of monoammonium phosphate, 0.05-2 parts of compound sodium nitrophenolate, 0.05-2 parts of rooting powder, 1-10 parts of EDTA chelated magnesium and 1-10 parts of boric acid. According to the hole applied fertilizer for the tobacco, growth and development of root systems of tobacco plants are promoted by fully utilizing a plant growth regulator, chelated trace elements and multiple functional elements such as amino acid according to the physiological habits of the tobacco, the effect is better, the functions are comprehensive, and the hole applied fertilizer is suitable for the tobacco crops in the early transplanting stage.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a seedling-raising fertilizer special for tobacco and a preparation method thereof. Background technique [0002] The various nutrients needed by tobacco throughout the field growth period are mainly absorbed from the soil. Judging from the status of soil nutrients in various ecological condition tobacco areas in my country, neither the quantity of nutrients nor the dynamic supply process can often meet the requirements for yield and quality of flue-cured tobacco. Therefore, it must be supplemented and adjusted through fertilization measures The supply of nutrients ensures the normal growth of flue-cured tobacco and achieves the purpose of high quality and high yield. Tobacco plants require sixteen essential nutrients for normal growth and development. Elements that require large amounts are carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, and s...

AI Technical Summary

Problems solved by technology

But the existing tobacco seedling-raising fertilizer is mostly used in the vigorous growth stage of tobacco, and secondly, it is not suitable for the tobacco in the initial stage of transplanting. Therefore, a kind of comprehensive and effective multi-functional seedling-raising fertilizer is needed to be used after tobacco transplanting to promote Tobacco roots grow and develop at the initial stage of transplanting, cultivate robust tobacco plants, increase stress resistance of tobacco plants, increase tobacco yield, and improve tobacco leaf quality
