Problems solved by technology

[0002] At present, grape fertilizers generally do not have a slow-release function. In addition, the nutrients in the fertilizer are not comprehensive, which leads to the ineffective absorption and utilization of the fertilizer during the growth of the grapes, resulting in malnutrition in the later stage. In addition, it is necessary to adjust the timing of fertilization during the fertilization process. Lead to nutrient imbalance and low fertilizer uptake and utilization, resulting in low grape yields

Abstract

The invention discloses a special fertilizer for grapes, which comprises the following components in parts by weight: 40-60 parts of urea, 10-20 parts of starch, 10-30 parts of formaldehyde, 3-8 parts of potassium dihydrogen phosphate, and 20 parts of potassium sulfate ~50 parts, 1~5 parts of borax, 5~10 parts of ferrous sulfate, 10~15 parts of zinc sulfate, 5~10 parts of ammonium molybdate, 2~10 parts of calcium carbonate, 2~5 parts of resin coating agent, water 100-200 parts, 2-10 parts of curing agent. The special fertilizer for grapes of the present invention is added with a resin coating agent so that the fertilizer can obtain a slow-release function, so that various elements of the fertilizer are slowly released in stages to supply the growth nutrient elements of the grapes. The present invention also provides a preparation method for the above-mentioned fertilizer. The method is simple and feasible, and is suitable for large-scale implementation.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a special fertilizer for grapes and its preparation method and application. Background technique [0002] At present, grape fertilizers generally do not have a slow-release function. In addition, the nutrients in the fertilizer are not comprehensive, which leads to the ineffective absorption and utilization of the fertilizer during the growth of the grapes, resulting in malnutrition in the later stage. In addition, it is necessary to adjust the timing of fertilization during the fertilization process. This leads to nutrient imbalance and low utilization rate of fertilizer absorption, resulting in low grape yield. Contents of the invention [0003] Purpose of the invention: the first technical problem to be solved by the present invention is to provide a special fertilizer for grapes. [0004] The second technical problem to be solved by the present invention pr...
