Multifunctional insecticide fertilizer for tomatoes and preparation method of multifunctional insecticide fertilizer

Abstract

The invention discloses a multifunctional insecticide fertilizer for tomatoes and a preparation method of the multifunctional insecticide fertilizer. The multifunctional insecticide fertilizer is prepared from the following raw materials in parts by weight: 31-31.62 parts of furfural residue, 13-13.4 parts of urea, 21-21.6 parts of potassium sulfate, 23-23.5 parts of monoammonium phosphate, 1.8-2 parts of zinc sulfate, 1.8-2 parts of polyvinyl alcohol, 1.8-2 parts of polyacrylamide, 2.1-3.2 parts of bactericide, 0.2-0.4 part of citric acid, 0.06-0.08 part of compound sodium nitrophenolate and 0.16-0.2 part of EDTA. The multifunctional insecticide fertilizer for tomatoes disclosed by the invention is reasonably and especially designed according to the plentiful-lack indexes of nutrients of the soil in Hexi corridor in Gansu Province, and the absorption ratio of the tomatoes on nutrient elements; a series of problems that a greenhouse tomato field in Hexi corridor in Gansu Province is unbalanced in ratio of macroelements to microelements, low in organic matter content, and poor in water retaining capacity, and generates soil hardening, alternaria solani, late blight, gray mold, viral disease, bacterial wilt, septoria lycopersici and the like are solved, and the multifunctional insecticide fertilizer integrates nutrition, disease prevention, soil improvement and water retention.

Description

technical field [0001] The invention relates to the technical field of agricultural chemical fertilizers, in particular to a multifunctional medicinal fertilizer for tomatoes. Background technique [0002] The tomato cultivation area in the solar greenhouse in the Hexi Corridor of Gansu Province has grown to more than 66,000 mu. At present, the main problems that are becoming more and more prominent are: the long planting period of greenhouse tomatoes, the occurrence of early blight, late blight, viral disease, gray mold, bacterial wilt and other diseases Serious; lack of tomato fertilizer products, excessive application of chemical fertilizers, low application of organic fertilizers, high tomato nitrate content, soil compaction, weak water and fertilizer retention capabilities; traditional compound fertilizers only have nutrients and do not have disease prevention effects , tomato diseases are serious, and the quality is low, which affects the sustainable development of the...
