Special macroelement water-soluble fertilizer for tobacco and preparation method of special macroelement water-soluble fertilizer

Abstract

The invention discloses a special macroelement water-soluble fertilizer for tobacco. The special macroelement water-soluble fertilizer comprises the following raw materials in parts by weight: 10-20 parts of monoammonium phosphate, 75-85 parts of potassium nitrate, 2-5 parts of anhydrous magnesium sulfate, 2-5 parts of boric acid, 0.5-1 part of ferrochel and 0.5-1 part of chelated zinc. The water-soluble fertilizer disclosed by the invention can quickly supplement macroelements and trace elements which are necessary to crops so as to promote absorption, utilization and conversion of the fertilizer, enhance the photosynthesis, promote the growth of the crops and enhance the resisting performance of the crops; when the special macroelement water-soluble fertilizer is used in the earlier stage of nutritional growth of the tobacco, the tobacco leaf yellowing time can be shortened, the tobacco harvesting times can be reduced, and the yellowing is uniform; the tobacco quality and the level can be improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural chemical fertilizers, and in particular relates to a large-element water-soluble fertilizer dedicated to tobacco and a preparation method thereof. Background technique [0002] Fertilizer is a direct or indirect supplier of nutrients needed for crop growth, and has the function of improving soil properties and improving crop yield and quality. However, ordinary fertilizers cannot be completely dissolved in water, and cannot be directly absorbed and utilized by the roots and leaves of crops. The effective absorption rate of crops is low, and the fertilizer effect is slow. Large or excessive application of chemical fertilizers not only causes problems such as low soil fertility utilization rate, nutrient imbalance, soil compaction, and soil microbial community imbalance, but also causes a series of environmental problems such as environmental pollution and nutrient enrichment. In recent years, ...

AI Technical Summary

Problems solved by technology

However, ordinary fertilizers cannot be completely dissolved in water, and cannot be directly absorbed and utilized by the roots and leaves of crops. The effective absorption rate of crops is low, and the fertilizer effect is slow.

Large or excessive application of chemical fertilizers not only causes problems such as low soil fertility utilization rate, nutrient imbalance, soil compaction, and soil microbial community imbalance, but also causes a series of environmental problems such as environmental pollution and nutrient enrichment. In recent years, chemical fertilizers have played an important role in environmental pollution The loss is as high as 100 billion yuan
