Dedicated chemical fertilizer for grape and preparation method thereof

Abstract

The invention discloses dedicated chemical fertilizer for grape. The dedicated chemical fertilizer is prepared from the following components in parts by weight: 25 to 30 parts of nitrogen fertilizer, 10 to 15 parts of phosphate fertilizer, 20 to 25 parts of potash fertilizer, 8 to 10 parts of magnesium sulfate, 20 to 30 parts of straw, 8 to 10 parts of sugar beet pulp, 5 to 10 parts of boron-magnesia fertilizer, 3 to 5 parts of zinc sulfate, 1 to 3 parts of chelate zinc, 3 to 5 parts of copper amino acid chelate, 3 to 5 parts of ammonium ferrous sulfate, 3 to 5 parts of humic acid, 3 to 5 parts of manganous sulfate, 3 to 5 parts of ammonium molybdate, 3 to 5 parts of amino acid, 1 to 3 parts of cnidium lactone and the like. The invention belongs to the technical field of agricultural fertilizer, and particularly provides the dedicated chemical fertilizer for the grape, which is comprehensive and balanced in nutrient, high in pertinence, and capable of effectively improving the structure of soil, increasing the yield of the grape, preventing and controlling plant diseases and insect pests and improving freezing resistance of grape plants, and a preparation method of the dedicated chemical fertilizer.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and specifically refers to a special chemical fertilizer for grapes and a preparation method thereof. Background technique [0002] The existing grape planting is usually a large-scale planting. Grape vines grow on the planting frame. With the optimization of grape varieties, the yield of grapes has greatly increased, and the demand for nutrients has also greatly increased. Traditional chemical fertilizers are mostly rice and grain fertilizers. , not according to the growth characteristics of grape cultivation, it is often necessary to apply a large amount of various chemical fertilizers to meet the nutritional needs of grape fruit, and these chemical fertilizers inevitably conflict with each other, affecting the utilization rate of chemical fertilizers, resulting in unabsorbed nutrients in the soil. Fertilizer accumulation, soil compaction. [0003] Grapes grow vigorously and p...

Problems solved by technology

In the prior art, inorganic fertilizers are mostly used, but long-term use will damage the soil aggregate structure, which will easily cause soil compaction and soil hardening, thereby affecting the growth of grapes and reducing the taste of grapes. At the same time, although simple organic fertilizers are rich in organic matter, However, the release of nutrients is slow, the absorption of grapes is slow, the fertilizer efficiency is low, and the effective balance of various effective nutrients cannot be achieved.

And after the grapes are picked, the grapes will be fertilized between October and November every year, but the existing fertilizers cannot prevent grape diseases and insect pests and enhance the frost resistance of the grape roots during winter. , decreased yield, poor taste
