Want to increase the production of grapes? Grape is a typical fruit tree, known as "potassium." Potassium can increase the cellulose content of grapes, enhance the ability of cold resistance, at the same time can promote the ripening of berries, which is conducive to the transfer of nutrients to berries, and increase the sugar content. . Grape is a perennial plant. It breeds rapidly, results early, yields quickly, and is not tolerant to cold. It has a wide adaptability to soil. The most suitable is sandy loam. The grape's reproductive cycle is divided into the period of injuring, sprouting, growth of new shoots, flowering, berry growth and maturation, dendrite maturation and dormancy. Among them, the flowering period and the berry growth and maturation period are the critical period for the grapes to need fertilizer. In order to maintain a strong growth of tree vigor and continuously improve the yield and quality of products, we must pay attention to rational fertilization. The first application of basal fertilizer should be based on organic fertilizers and fertilizers. Young trees apply 20-30 kilograms of organic fertilizer per plant, 30-50 kilograms per tree at the beginning, and 50-100 kilograms per mature plant. Every 100 kg of organic fertilizer is mixed with compound fertilizer (45% of total nutrients) 1-2 kg. Like other fruit trees, it is advisable that the basal fertilizer be applied after the grapes are harvested, and the sooner the better. The basal fertilizer is applied in a disc form method. The soil is gradually deepened from the inside to the outside of the tree tray. The soil is removed 15 cm deep in the root and 30-40 cm deep in the far root. The organic fertilizer is spread in the pan and mixed with the soil. Then cover the removed soil. It is also possible to excavate a groove 60-80 cm wide and 60-cm deep on both sides of the tree from the trunk, apply fertilizer, and fill the groove with the soil. Followed by fertilizer generally 2-3 times. Shoot shoots increase the rate of fruit set. Into the berry growth period, the third top dressing. At this time, fruit enlargement and weight gain and new flower bud differentiation should be performed for the first time before flowering. The general practice is to apply 1-1.5 kg per plant and apply it to a small ditch. If no basal fertilizer is applied in the fall of last year, organic fertilizer should be applied. The fertilizer is mainly to promote new sprouting, branching, flowering and fruit set. If there are many ear and fruit set, the top dressing may be applied for the second time before the berry is grown (about the beginning of July), and about 1 kilogram of high-potassium compound fertilizer is applied per plant to reduce fruit drop and consume large amounts of nutrients. This period requires a large amount of fertilizer, and is divided into nitrogen and potassium nutrition, should use compound fertilizer, about 2 kg per plant. After harvesting, the topdressing is performed for the fourth time and it can generally be combined with basal fertilizer. Once again, rootless fertilization is one of the fruit trees that are sensitive to trace elements such as boron, manganese, zinc and iron. Spray 0.1%-0.2% borax solution, 0.2% manganese sulfate solution, 0.2%-0.3% zinc sulfate solution and 0.5%-0.1% ferrous sulfate solution during the grape growing period.
