Problems solved by technology

Most of the conventionally used inorganic trace element fertilizers are used once when transplanting tobacco in the field or when topdressing seedling fertilizer. Improper use of this method will directly increase the salt concentration of the soil microenvironment in the roots of tobacco plants in the early stage. It is easy to produce physical and chemical reactions, turning water-soluble elements into water-insoluble or insoluble elements, which reduces t

Abstract

The invention relates to an organic nutrition regulator for tobacco and a preparation method of the organic nutrition regulator. The organic nutrition regulator is characterized by being preparing from the following raw materials in parts by weight: 6-15 parts of potassium fulvic acid, 1-6 parts of chitosan, 1-6 parts of alginic acid, 10-20 parts of urea, 15-25 parts of potassium dihydrogen phosphate, 25-35 parts of potassium nitrate, 1-7 parts of borax, 3-8 parts of zinc sulfate heptahydrate, 0.5-3 parts of ferrous sulfate heptahydrate, 0.5-2.5 parts of sodium dodecyl sulfate, 5-10 parts of sodium ethylene diamine tetracetate and 100 parts of water. The organic nutrition regulator has comprehensive nutrient components; the proportion of nutrient elements is more suitable for the growth requirement of tobacco, the absorption effect of the nutrient elements by the tobacco is good; since the organic nutrition regulator is free of any artificially synthesized plant nutrition regulator, the organic nutrition regulator is friendly to crops and environment; in addition, the drought resistance, cold resistance and disease resistance of the tobacco and the quality of tobacco leaves can be improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and relates to an organic nutrition regulating agent for tobacco and a preparation method thereof. Background technique [0002] In my country's tobacco agricultural production, the long-term application of a large amount of chemical fertilizers has caused a series of soil and environmental pollution problems. If fertilization is improper, the quality of tobacco leaves will be reduced to a certain extent. If the flue-cured tobacco is planted in a full chemical fertilizer environment, the regional characteristics of the tobacco leaves will also be reduced or even disappear. In 2010, the Ministry of Agriculture of the People's Republic of China proposed "balanced fertilization" throughout the country. The purpose of this initiative is to greatly increase the yield of cultivated land and save fertilizer. However, the problem of large-scale non-point source pollution and fertilizer dam...
