Abstract

The invention relates to a preparation method of a chemically synthesized water-soluble fertilizer special for different growth stages of tomatoes, which belongs to the technical field of production of chemical fertilizers. According to the method, agricultural monoammonium phosphate, agricultural potassium chloride, urea and the like are used as main raw materials, and the fully-crystallized water-soluble fertilizer with stable chemical composition is prepared by means of chemical polymerization and the like according to nutrient absorption rules of tomatoes in different growth stages. The chemically synthesized special water-soluble fertilizer for tomatoes has the characteristics of easiness in absorption, difficulty in moisture absorption and caking, excellent physicochemical properties and the like. By applying the special water-soluble fertilizer for the tomatoes, the yield and quality of the tomatoes can be remarkably improved, the utilization rate of the fertilizer is increased, and residues of the fertilizer in soil are effectively reduced.

Description

[0001] 1. Technical field [0002] The invention relates to a water-soluble fertilizer, in particular to a method for preparing and using a chemically synthesized tomato-specific water-soluble fertilizer, and belongs to the technical field of fertilizer production. [0003] 2. Background technology [0004] Tomato (scientific name: Solanum lycopersicum) is an annual or perennial herbaceous plant belonging to the Solanaceae family. It is widely cultivated in the north and south of my country, and it is one of the main crops planted in off-season facilities in the north of my country. The fruit of tomato is rich in nutrition, rich in carotene, Vb, Vc, etc., and has a unique flavor. It can be eaten raw, cooked, processed in tomato sauce, juice or stored in cans. [0005] Correct fertilizer application is one of the main factors related to tomato yield and quality. At present, there are two main problems in fertilization during tomato planting. One is that the amount of fertilizat...
