The combination of farmyard manure and fertilizer is one of the important measures for viticulture management. The experienced fruit growers pay great attention to the autumn fertilization. During the period from harvesting to soil freezing, farmer fertilizer is used as the base fertilizer. The basal fertilization is often implemented in a ditch with a ditch depth of 50 cm and a width of 30 cm.
The annual growth of grapes is very large, and it is a need for fertilizer crops. It is not enough to apply farmer's home-based fertilizer as a base fertilizer, and quick-impact fertilizer should be applied. When applying topdressing, apply a shallow ditch at a distance of 45 cm from the plant and immediately cover the soil with water after topdressing. Grape topdressing, mainly in the growth of nitrogen fertilizer, young fruit growth period of nitrogen fertilizer with phosphorus and potassium, berry coloring period and shoot maturity of the main phosphorus and potassium, with a suitable amount of nitrogen fertilizer. The Kyoho varieties fall heavily and have serious fruit drop. They should not chase nitrogen fertilizer before flowering. They must be applied after fruit setting. In the pre-growth stage, the combination of spraying can be used for extra-root dressing, 0.3% urea solution is sprayed during the growth period of the shoot, and 0.3% borax solution is sprayed before flowering to promote pollination and increase the fruit setting rate. In the berry enlargement to the berry coloring period, spray 2 to 3 times potassium dihydrogen phosphate solution. The concentration of 0.3% increases the yield and quality of berries. According to the survey, the general fertility park applies 75,000 kilograms per hectare per year. In the old production area, the annual production of vinegar is 0.15 kg per plant and 2 kg of plant ash. The fences each year apply 0.1 kg of urea per plant and 1 kg of plant ash.
