Problems solved by technology

These foliar fertilizers are not only suitable for flue-cured tobacco, but also can be applied to other crops. Therefore, the nutrient distribution ratio cannot be prepared according to the growth and development of flue-cured tobacco, the characteristics of nutritional requirements and the prone to element deficiency. The specificity is poor; at the same time, the current flue-cured tobacco production sprays more foliar fertilizers, either in an organic nutritional state, or a single fertilizer with inorganic nutrition, such as potassium dihydrogen phosphate, zinc sulfate, etc., lacking the combination of organic and inorganic, A special foliar fertilizer with a multi-nutrient ratio and suitable for spraying on the leaves of flue-cured tobacco, a special economic crop

Abstract

The invention relates to a special compound fertilizer for being sprayed to flue-cured tobacco leaves. The special compound fertilizer includes, by weight, 3-6% of copper sulfate, 15-25% of zinc sulfate, 3-6% of borax, 2-3% of epsom salt, 2-3% of manganese sulfate monohydrate, 5-7% of citric acid anhydrous food grade and 50-70% of monopotassium phosphate. The fertilizer can be sprayed to the tobacco leaves and absorbed by the tobacco leaves during the resettling stage, the fast growing stage and the dome stage of flue-cured tobaccos, nutrition is supplemented for the flue-cured tobaccos, elements are coordinated to be balanced, metabolic intermediates are increased, potassium deficiency and microelement nutrient deficiency symptom of the flue-cured tobaccos are well solved, growth and development of the flue-cured tobaccos and substance metabolism and composition are promoted, the potassium content of the flue-cured tobacco leaves is increased, and the appearance quality and the sensory evaluation quality of the flue-cured tobaccos are improved.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco fertilizers, and specifically relates to a special compound fertilizer which contains various inorganic nutrients and small molecular organic compounds and is suitable for spraying on flue-cured tobacco leaves. Spray. Background technique [0002] The growth and development of flue-cured tobacco requires macronutrients, secondary elements and micronutrients. Different nutritional elements have different physiological functions and play an important role in the growth and development of tobacco plants and substance metabolism. Affected by soil nutrients, tobacco field fertilization, tobacco plant growth and ecological environment, different symptoms of nutrient element deficiency often appear in flue-cured tobacco production, such as potassium deficiency, boron deficiency, zinc deficiency, etc. After the tobacco plants lack nutrient elements, it takes a long time for fertilizer conversi...
