Special-purpose tuanke foliage fertilizer for flue-cured tobacco

Abstract

The present invention is spherical plant foliar fertilizer especially used for flue-cured tobacco, which is basically composed of the following substances: fulvic acid, zinc sulfate, copper sulfate, ferrous sulfate, boric acid, potassium dihydrogen phosphate, potassium nitrate, rooting powder, ammonium molybdate and acetic acid. Wherein, the ferrous sulfate refers to the ferrous sulfate heptahydrate; the copper sulfate refers to the copper sulphate pentahydrate; the zinc sulfate refers to the zinc sulfate heptahydrate; the acetic acid refers to the acetic acid glacial; the ammonium molybdate and the boric acid are without crystal water. The production method of the foliar fertilizer is as follows: first, a certain amount of 36% acetic acid is added to the mixture of the 25 g / L fulvic acid, followed by zinc sulfate, copper sulfate, ferrous sulfate, boric acid, potassium dihydrogen phosphate and potassium nitrate in sequence, and then 0.1% alcohol containing 5g/L rooting powder is also added to the 25 g / L fulvic acid; then, upon ongoing stirring, 145g/L ammonium molybdate is slowly added to the mixture of the 25 g / L fulvic acid; the mixture is then shaken up and filled into a glass or plastic bottle(do not use metal containers), and then the bottle is sealed, and the spherical plant foliar fertilizer is thus obtained. Compared with the similar foliar fertilizer, the foliar fertilizer provided by the invention can significantly promote the growth and development in tobacco plant resettling period and budding period, markedly increase the yield and value of flue-cured tobacco, significantly increase potassium content of flue-cured tobacco and reduce chlorine content to enable more moderate nicotine content and coordinated chemical composition of tobacco leaves. Therefore, the invention has significant economic and social benefits.

Description

Technical field: [0001] The invention relates to a special foliar fertilizer for flue-cured tobacco, in particular to a special tuanke foliar fertilizer for flue-cured tobacco. Background technique: [0002] Fertilization of flue-cured tobacco has become one of the key technical measures to produce high-quality and high-yield tobacco. During the growth period of flue-cured tobacco, reasonable and balanced fertilization can not only promote the healthy growth of flue-cured tobacco, reduce diseases and insect pests, but also increase the yield of tobacco leaves and improve the quality of tobacco leaves. [0003] As a type of fertilizer, foliar fertilizer has been widely used in flue-cured tobacco production because of its convenient use, high fertilizer efficiency, and easy absorption. The cluster stage of flue-cured tobacco growth is a key vegetative growth period for tobacco plants to grow rapidly and absorb the most nutrients. Proper and reasonable fertilization in this period i...

Problems solved by technology

The clump stage of flue-cured tobacco growth is a key vegetative growth period for tobacco plants to grow rapidly and absorb the most nutrients. Appropriate and reasonable fertilization during this period is very important for the good growth of tobacco plants in the later stage and the improvement of tobacco leaf yield and quality; however, at present, the market The flue-cured tobacco foliar fertilizers
