Fertilizer specially used for summer black grape, preparation method and application thereof

Abstract

The invention discloses a fertilizer specially used for summer black grapes, a preparation method and an application thereof. The fertilizer includes following raw materials, by weight, 40-60 parts of urea, 3-8 parts of potassium dihydrogen phosphate, 20-50 parts of potassium sulfate, 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 a resin film coating agent, 100-200 parts of water, 2-10 parts of gibberellins and 2-10 parts of forchlorfenuron. In the fertilizer specially used for the summer black grapes, a slowly releasing function is achieved through addition of the resin film coating agent so that various elements in the fertilizer are slowly released for supplying growth nutritional elements to the grapes in different periods. Through addition of an expanding agent, an expanding effect is achieved in the summer black grapes on the basis of obtaining common fertilizers. In addition, the preparation method is simple and available and is suitable for being carried out in large scales. When the fertilizer is applied for inducing fruit setting, a fruit setting rate of the summer black grapes can maximumly reach 88.95%.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a special fertilizer for summer black grapes and its preparation method and application. Background technique [0002] At present, the fertilizers for summer black grapes generally do not have a slow-release function. In addition, the nutrients in the fertilizers are not comprehensive, which leads to the ineffective absorption and utilization of fertilizers during the growth of summer black grapes, resulting in malnutrition in the later stage. In addition, reasonable adjustments are also required during the fertilization process. The timing of fertilization leads to nutrient imbalance and low fertilizer absorption and utilization rate, resulting in low grape yield. The current Xiahei fertilizer does not add bulking agent, and it is generally added separately, not through fertilizer.

[0002] At present, the fertilizers for summer black grapes generally do not have a slow-release function. In addition, the nutrients in the fertilizers are not comprehensive, which leads to the ineffective absorption and utilization of fertilizers during the growth of summer black grapes, resulting in malnutrition in the later stage. In addition, reasonable adjustments are also required during the fertilization process. The timing of fertilization leads to nutrient imbalance and low fertilizer absorption and utilization rate, resulting in low grape yield. There is no expansion agent added to the current summer black fertilizer, and it is generally added separately, not through the fertilizer.
