Red grape is a late-maturing variety, which is resistant to storage and transportation, high in yield, hard and brittle flesh, sweet and not sour. Some varieties also have special aromatic flavor, which is very popular among consumers. Unlike conventional grape fertilization management, it needs special treatment. The topdressing of the topdressing roots is mainly based on the application of quick-acting fertilizers. According to the size of the plants, the ditch is 30-40 cm wide and 30 cm wide, and the fertilizer mixed soil is buried in the ditch, and then the water is poured. Root topdressing can be quickly absorbed by plants, promote the growth and development of branches and leaves, and also improve soil. Foliar spray fertilizer, in the sand land where water and fertilizer are easy to lose, the application of this method is better. The method is to dissolve the chemical fertilizer in water and spray it evenly on the plant at a certain concentration. The fertilizer solution penetrates into the plant through green parts such as leaves, young shoots and young fruit. During the topdressing period, the red grape was harvested later, and it was necessary to pursue the delayed harvesting of fertilizer. In autumn, in order to promote fruit ripening early, coloring is good, and the branches are full, it is necessary to apply and spray ripening fertilizer, mainly based on phosphorus-potassium compound fertilizer. In order to meet the nutrient consumption of the grapes on the plants, it is necessary to apply the delayed harvesting fertilizer to the ternary compound fertilizer. The amount of topdressing, production depends on the growth, appearance and soil structure of the vines, as well as the soil fertility and the strength of the fertility to determine the amount of fertilizer and the number of top dressings. The base fertilizer is based on the farmer's manure, sometimes mixed with a certain amount of fertilizer, applied to the soil at the base of the vine. The base fertilizer is applied after the fruit is harvested until the soil is frozen. Appropriate early fertilization is beneficial to the decomposition of organic fertilizers and root wound healing, and can restore the ability of plants to absorb nutrients, improve cold resistance and drought resistance, and provide a good foundation for spring root activity, flower buds to continue differentiation and shoot growth. condition. Generally, every 1 to 2 years, combined with the expansion of the hole between the rows, the base fertilizer is applied once. The fertilization ditch is 60-80 cm deep and 30-40 cm wide, and is alternately fertilized by means of interlacing or two sides. Each plant is applied with about 100 kg, and then water is sealed.
