Special compound fertilizer for tomato

Abstract

The invention relates to the field of fertilizers, and concretely relates to a special compound fertilizer for tomato. The fertilizer is prepared from the following raw materials, by weight, 25-35 parts of urea, 10-20 parts of monoammonium phosphate, 15-25 parts of calcium superphosphate, 7-9 parts of potassium sulfate, 0.5-0.7 parts of zinc sulfate, 0.1-0.3 parts of manganese sulfate, 0.7-0.9 parts of borax, 0.2-0.4 parts of copper sulfate, 0.5-0.7 parts of iron sulfate and 6-8 parts of lignite. The special compound fertilizer for tomato has substantial yield increase and value increase benefits in practical application. The fertilizer is a ternary compound fertilizer containing N, P and K, and can fundamentally solve the problems of unbalanced nutrients, low output and low quality in tomato production. Humic acid (lignite) capable of promoting the growth of crops and improving the fertilizer efficiency is added, so the fertilizer can be applied as a base fertilizer or an after fertilizer. The fertilizer can improve the environment benefit of soil, and is a sustainable and safe fertilizer in the field of vegetables.

Description

[0001] technical field [0002] The invention relates to the field of fertilizers, in particular to a special compound fertilizer for tomatoes. Background technique [0003] Tomato, the fruit is rich in soluble sugar, organic acid, protein, vitamin C, carotene and other nutrients. It has high nutritional value and is one of the main vegetables in the north. In recent years, facility agriculture in the northern region has developed rapidly, and its quantity and area have increased dramatically. However, due to the lack of reasonable fertilization guidance, the application of chemical fertilizers is increasing day by day, and the phenomenon of heavy nitrogen, light phosphorus, and no potassium application is extremely serious. Not only the yield of tomatoes is low, the quality is poor, and even lead to the accumulation of soil salt, and the soil physical and chemical properties are poor. [0004] my country is a large agricultural country, and the demand for fertilizers is hu...
