Sepiolite carbon-based slow release fertilizer specially used for grapes and preparation method thereof

Abstract

The invention discloses a sepiolite carbon-based slow release fertilizer specially used for grapes and a preparation method thereof. The sepiolite carbon-based slow release fertilizer specially used for grapes is prepared from the following raw materials in parts by weight: 20-30 parts of wheat straws, 10-15 parts of walnut-tree barks, 5-10 parts of sunflower seed shells, 5-10 parts of bagasse, 8-12 parts of sepiolite powder, 4-6 parts of coal cinders, 10-15 parts of spent pulping liquor, 3-5 parts of tobacco powder, 4-6 parts of garlic stems, 2-3 pars of castor leaves, 3-4 parts of bitter melon leaves, 3-5 parts of paternoster tree barks, 15-25 parts of urea, 10-15 parts of diammonium phosphate, 8-12 parts of ammonium sulfate, 4-6 parts of potassium sulfate, 2-4 parts of zinc sulfate, 1-2 parts of a boric acid, 5-8 parts of diatomite, 3-6 parts of powdered rock phosphate, 1-2 parts of used oil, 4-6 parts of water soluble chitosan, 3-4 parts of sodium alginate, 2-3 parts of wood vinegar, and a proper amount of water. The slow release fertilizer prepared by using the method disclosed by the invention is good in slow release effect and high in fertilizer utilization rate; and after being applied once, the fertilizer can meet the needs of grapes on nutrients during the whole growing period, thereby reducing the application amount of the fertilizer and the fertilization frequency, reducing the production cost, and reducing the environment pollution.

Description

technical field [0001] The invention relates to a special slow-release fertilizer for seafoam charcoal-based grapes and a preparation method thereof, belonging to the technical field of fertilizers. Background technique [0002] Grapes are one of the most popular fruits. They have high nutritional value and can be made into grape juice, raisins and wine. Grape cultivation in China has a history of more than 2,000 years. In recent years, with the continuous improvement of grape planting benefits, more and more fruit growers are planting grapes. At present, the fertilizers used by fruit growers to plant grapes are mainly instant fertilizers, which dissolve quickly in the soil. If they are applied too much at one time, they will not only damage the root system, but also cause the loss of nitrogen and potassium fertilizers and the fixation of phosphorus fertilizers by the soil, reducing the utilization rate of fertilizers. There are also problems such as excessive application o...

Problems solved by technology

At present, the fertilizers used by fruit growers to plant grapes are mainly instant fertilizers, which dissolve quickly in the soil. If they are applied too much at one time, they will not only damage the root system, but also cause the loss of nitrogen and potassium fertilizers and the fixation of phosphorus fertilizers by the soil, reducing the utilization rate of fertilizers. There are also problems such as excessive application of fertilizers, unbalanced nutrient ratios, and low fertilizer utilization rates.
