Problems solved by technology

However, in my country's viticulture, the habit of using large amounts of water and large amounts of fertilizers is continued, and the phenomenon of excessive application of chemical fertilizers is becoming more and more serious. The average amount of chemical fertilizers is 2565kghm -2 , not only often cause unstable yields, but also cause weak trees to overwinter, and cause environmental pollution

Embodiment 1

[0026] Mix and stir 45.308 parts of powdered urea, 12.673 parts of monoammonium phosphate, 16.507 parts of potassium nitrate, 1.688 parts of calcium nitrate, and 16.507 parts of potassium dihydrogen phosphate, and set aside for use. 1.521 parts of magnesium sulfate, 3.212 parts of borax, EDTA-Fe2. 164 parts, 0.211 parts of EDTA-Mn, 0.100 parts of EDTA-Cu, 0.100 parts of EDTA-Zn and 0.015 parts of ammonium molybdate are mixed and stirred evenly. Special fertilizer for grape full nutrition drip irrigation. The fertilizer contains 0.97% water, which meets the production requirements of high-concentration compound fertilizer.

Embodiment 2

[0028] Field application of special fertilizer for full nutrient drip irrigation of wine grapes:

[0029] The special fertilizer for full nutrition drip irrigation of wine grapes is applied together with the grape irrigation. The specific method is that according to the growth process of the grapes, the fertilizer is weighed and poured into the fertilization pipe, and the external fertilizer applicator and water supply pipe are evenly applied to the tree row with the irrigation water.

Abstract

The invention relates to a full-nutritional and full-water-soluble drip-irrigation special fertilizer for wine grapes, belonging to the field of fertilizers. The special fertilizer comprises urea, monoammonium phosphate and potassium nitrate; the special fertilizer is characterized by being prepared from the following components by ratio: 44-47% of urea, 11-14% of monoammonium phosphate, 15-18% of potassium nitrate, 1-2% of calcium nitrate and 15-17% of potassium dihydrogen phosphate; the full-nutritional and full-water-soluble drip-irrigation special fertilizer for the wine grapes is prepared by the steps of evenly mixing the components for later use; evenly mixing 1.2-1.8% of magnesium sulfate, 2.7-3.5% of borax, 1.8-2.4% of ethylene diamine tetraacetic acid (EDTA)-Fe, 0.2-0.3% of EDTA-Mn, 0.08-0.15% of EDTA-Cu, 0.09-0.13% of EDTA-Zn and 0.01-0.12% of ammonium molybdate; evenly mixing the obtained mixtures, and carrying out split charging. The full-nutritional and full-water-soluble drip-irrigation special fertilizer for the wine grapes is comprehensive in nutrition, good in water solubility, convenient in application and easy in widespread promotion and application.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a special fertilizer suitable for full nutrition and full water soluble drip irrigation of wine grapes in the semi-arid climate area of ​​Northwest China. Background technique [0002] Among the five major elements of agricultural production, light, temperature, air, water, and nutrients, water and fertilizer are mainly controlled by humans under current production conditions; artificial water and fertilizer are the two key factors that limit crop production in the vast arid and semi-arid regions of Northwest China. One of the key technologies to solve the contradiction of water and fertilizer supply in arid areas is to implement the integrated and precise supply of water and fertilizer under water-saving irrigation. According to the characteristics of soil fertilizer supply and the law of crop fertilizer demand in different regions, on the basis of the experiment...
