Fertilizer capable of improving tobacco soil and promoting growth of root

Abstract

The invention relates to a fertilizer capable of improve the tobacco soil and promote the growth of roots. The fertilizer comprises the following components by weight percent: 60-90% of humus type organic carrier, 4-10% of rooting powder or root growth promoter, 2-5% of plant growth hormone, 2-5% of potassium sulfate and 2-10% of secondary element / trace element fertilizer. By using the fertilizer of the invention, the soil can be improved, the soil organic matters can be increased, the soil organic and inorganic composites can be improved, the water-stable aggregate structure is easy to form, the supply of soil nutrients can be coordinated, the growth of plant roots can be promoted, the effectiveness of nutrients in soil can be increased, the potassium content of plant tissues can be increased, the organic matters of the tobacco soil can be increased, the effectiveness of nutrients in the tobacco soil can be increased, the growth of tobacco can be promoted, the potassium content of tobacco leaves can be increased, the quality of the flue-cured tobacco leaves can be improved, and the fragrance of tobacco leaves can be increased. By using a defined amount of the fertilizer of the invention, the absorption of the flue-cured tobacco to heavy metals such as arsenic can be reduced, the heavy metal enrichment factor of the flue-cured tobacco can be reduced and the contents of heavy metals such as arsenic in soot and smoke can also be reduced.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a root-promoting fertilizer for soil improvement in tobacco fields. Background technique [0002] Tobacco is a special foliar economic crop with high economic value. my country is the largest producer in the world, and more than 1.4 million ha of tobacco are planted every year. 2 , the output of tobacco leaves is more than 1.7 million tons, and the consumption accounts for about 1 / 3 of the world. Taxes and profits of the tobacco industry account for about 10% of the country's fiscal revenue, making important contributions to the healthy and rapid development of the national economy. However, for a long time, due to the limitation of land resources, most of the tobacco fields in my country have adopted the continuous cropping method for a long time. In the production, they often only pay attention to the input of chemical fertilizers, while ignoring the application of organic fertilize...

Problems solved by technology

[0004] At present, the improper application of flue-cured tobacco fertilizer is the main limiting factor for the further improvement of tobacco leaf quality in most tobacco areas in my country. Tobacco production has low fertilizer utilization rate and tobacco quality cannot meet the requirements of "high quality and suitable production". The single application of a large amount of nutrients affects the improvement of the yield and quality of flue-cured tobacco. How to choose the fertilizer suitable for the tobacco field, thereby improving the fertilizer utilization rate, improving the quality of tobacco leaves and improving the soil environment is the key issue for improving the quality of tobacco leaves
