Special water-soluble fertilizer for grapes

Abstract

The invention relates to the technical field of plant water-soluble fertilizers and particularly discloses a special water-soluble fertilizer for grapes. The nutrient solution is prepared from 120 to150 parts of manganese sulfate, 40 to 60 parts of ammonium nitrate, 30 to 50 parts of triple superphosphate, 90 to 110 parts of monopotassium phosphate, 230 to 260 parts of potassium nitrate, 100 to 130 parts of zinc sulfate, 3 to 8 parts of a pH regulator, 7 to 10 parts of boric acid, 3 to 6 parts of inorganic gel particles and 80 to 120 parts of water. The preparation method comprises the following steps: 1) treating the potassium dihydrogen phosphate and potassium nitrate with inorganic gel particles to obtain potassium dihydrogen phosphate and potassium nitrate with slow release property;and 2) carrying out high-speed mixing and dispersing treatment on the raw material components to obtain the special slow-release water-soluble fertilizer for grapes. The water-soluble fertilizer provided by the invention can rapidly supplement macroelements and nutrients necessary for grapes in the growth period, improves the fertilizer efficiency utilization rate of the water-soluble fertilizer,promotes the absorption, utilization and conversion of the fertilizer by the grapes, enhances the photosynthesis of the grapes, promotes the growth and development of the grapes, enhances the stress resistance of the grapes, increases the yield of the grapes and improves the quality of the grapes.

Description

technical field [0001] The invention relates to the technical field of plant water-soluble fertilizers, and specifically discloses a slow-release water-soluble fertilizer specially used for grapes. 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 various 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 world's total fruit output. At present, my country's grape planting area is about 6 million mu, accounting for about 5.0% of the world's ...

Problems solved by technology

In addition, if the water-soluble compound fertilizer is dissolved in water, if the plants cannot absorb it in time, the soluble potassium ions and other nutrients will seep into the ground, which will not only cause the loss of fertilizer efficiency, but also pollute the groundwater.

[0005] Therefore, it is of great significance to develop a special water-soluble fertilizer that conforms to the law of nutrient absorption in the grape growth cycle, and can solve the problem that phosphorus is easily fixed by the soil and potassium is easy to lose.
