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

Embodiment 1

[0020] A kind of special compound fertilizer for flue-cured tobacco leaves. The weight percentage of each raw material is as follows: copper sulfate 4%, zinc sulfate 20%, borax 5%, magnesium sulfate heptahydrate 2.5%, manganese sulfate monohydrate 2.5%, anhydrous lemon Acid 6%, potassium dihydrogen phosphate 60%.

Embodiment 2

[0022] A kind of special compound fertilizer for flue-cured tobacco leaves. The weight percentage of each raw material is as follows: copper sulfate 3%, zinc sulfate 15%, borax 6%, magnesium sulfate heptahydrate 2%, manganese sulfate monohydrate 3%, anhydrous lemon Acid 5%, potassium dihydrogen phosphate 66%.

Embodiment 3

[0024] A special compound fertilizer sprayed on flue-cured tobacco leaves. The weight percentages of the raw materials are as follows: copper sulfate 6%, zinc sulfate 25%, borax 3%, magnesium sulfate heptahydrate 3%, manganese sulfate monohydrate 2%, anhydrous lemon Acid 7%, potassium dihydrogen phosphate 54%.

[0025] The preparation method of the compound fertilizer described in the above embodiment: prepare according to the weight ratio of each raw material, and use powder as much as possible for the raw material. If there are agglomerates or crystal-like connected small pieces, crush them first, and mix them thoroughly in a plastic container. It can weigh 250g and put it into a plastic bag with the name of the fertilizer and how to use it.

[0026] Usage and dosage: 250g of fertilizer sprayed per acre, and the spraying concentration is 0.3-0.5%.

Abstract

The invention relates to a special compound fertilizer for spraying flue-cured tobacco leaves. The weight percentages of the raw materials are as follows: 3-6% of copper sulfate, 15-25% of zinc sulfate, 3-6% of borax, and 2-3% of magnesium sulfate heptahydrate , manganese sulfate monohydrate 2-3%, anhydrous citric acid 5-7%, potassium dihydrogen phosphate 50-70%. The fertilizer can be sprayed and absorbed by foliar spraying in flue-cured tobacco during the cluster stage, flourishing period and dome stage, supplementing the nutrition of flue-cured tobacco, coordinating the balance of elements, increasing intermediate metabolites, and better solving the deficiency of potassium and trace elements in flue-cured tobacco. Promote the growth and development of flue-cured tobacco and the metabolism and synthesis of substances, increase the potassium content of flue-cured tobacco leaves, and improve the appearance quality and sensory evaluation quality of flue-cured tobacco.

Description

Technical field [0001] The invention belongs to the technical field of flue-cured tobacco fertilizers, and specifically relates to a special compound fertilizer containing a variety of inorganic nutrient elements and small molecular organic compounds and suitable for spraying flue-cured tobacco leaves. Spray. Background technique [0002] The growth and development of flue-cured tobacco requires a large number of elements, medium elements and trace elements. Different nutrient elements have different physiological functions and play an important role in the growth and development of tobacco plants and material metabolism. Affected by soil nutrients, tobacco field fertilization, tobacco plant growth and ecological environment, different symptoms of nutrient element deficiency diseases, such as potassium deficiency, boron deficiency, and zinc deficiency, often occur in flue-cured tobacco production. After the tobacco plants lack nutrients, through the soil topdressing, fertilizer ...
