Abstract

The invention relates to a special controlled-release water soluble fertilizer for grapes and a preparation method of the special controlled-release water soluble fertilizer. The controlled-release water soluble fertilizer is prepared from the following raw materials in parts by weight: 190-230 parts of ammonium nitrate, 40-60 parts of ammonium dihydrogen phosphate, 30-50 parts of triple superphosphate, 90-110 parts of monopotassium phosphate, 230-260 parts of potassium nitrate, 100-130 parts of potassium sulfate, 30-60 parts of chelated medium trace element mixture, 7-10 parts of borax and 3-6 parts of inorganic gel particle. The preparation method comprises the following steps: (1) treating monopotassium phosphate and potassium sulfate by use of the inorganic gel particle to obtain controlled-release monopotassium phosphate and potassium sulfate; and (2) mixing and dispersing the raw material components at a high speed to obtain the controlled-release water soluble fertilizer. According to the special controlled-release water soluble fertilizer for grapes, a part of phosphorus and potassium nutrients in the controlled-release water soluble fertilizer have slow release feature, so that the water soluble fertilizer is in accordance with the law of the nutrient absorption in a grape growth period, the fertilizer efficiency utilization rate of the water soluble fertilizer is improved and the controlled-release water soluble fertilizer has high market application value.

Description

technical field [0001] The invention relates to a special slow-release water-soluble fertilizer for grapes and a preparation method thereof. More specifically, the invention relates to a slow-release water-soluble fertilizer special for grapes and a preparation method thereof, belonging to the field of special water-soluble fertilizers. Background technique [0002] The sugar content of grapes is as high as 10% to 30%, mainly glucose, and also contains a lot of minerals, proteins, vitamins, and many amino acids needed by the human body. It is a delicious and nutritious fruit. A large amount of fruit acid in grapes is helpful for digestion. Eating more grapes properly can strengthen the spleen and stomach. Regular consumption of grapes is of great benefit to neurasthenia and excessive fatigue. [0003] Grape is one of the world's four major tree species. It has strong adaptability. Humans have planted grapes for thousands of years, with high yields, accounting for 1 / 4 of the ...
