How to manage newly planted grapevines

The grape planted in the same year should be early fruit and high yield, in the cultivation management should grasp the following measures: fertilization should be applied frequently and thinly in the growing season of grapes, so as to reduce fertilizer damage and waste, thus promoting the good growth and development of new shoots, laying a solid foundation for early formation, early bearing and high yield. Technically, fertilizer should be applied once a month from grape germination to late August, with 5 kg of water and fertilizer and 50 g of nitrogen fertilizer for each plant. If there is little rain in July and August, the grape plants should be covered with weeds, cultivated for drought resistance and irrigated. Stand and summer shear grape is a vine climbing plants, to stand in order to achieve high yield. Therefore, in the year of planting, should be set up early. Plants that cannot stand on trestles should also stand on semi-trestles to attract new shoots and increase their polar growth. In winter, however, it is necessary to erect shelves, otherwise it will affect the growth of the following year. Grape germination, when the new shoots grow to a certain length (about 20 cm), optional leave a stout new shoots do the main branch, the rest of the tender shoots erased. Under good fertilizer and water management conditions, the annual growth of grapes can reach 4~5 meters. In order to promote the formation of accessory shoots, the new shoots should be removed when they grow to the height of the frame surface, and the tendrils should be removed. Tendrils are often neglected by fruit growers in production, which is one of the important factors affecting early bearing and high yield, because tendril buds can differentiate into flower buds under good fertilizer and water management conditions if environmental conditions are suitable. During winter pruning, accessory shoots can be used as backbone branches to form plants earlier. Keep the soil loose in the garden all the year round. Due to the increase of fertilization times and the wetting of rain, the soil in the garden is easy to harden, which is not conducive to the growth and development of plant roots (grape belongs to fibrous root system, and its growth and development are not strong in that year). If the soil in the garden can be kept loose all year round, the growth of technical shoots can be increased by 15%~30% compared with general management, and the damage and occurrence of diseases and insect pests can be reduced. Pay attention to the prevention and control of diseases and insect pests The grape diseases planted in the same year are generally light, but the plants planted last winter have not been quarantined and disinfected due to external transfer and transportation. Some grapes will have signs of disease, such as black pox, powdery mildew, etc., and should be sprayed in time for prevention and control. Powdery mildew can be sprayed 1000 times the liquid of Tobzin or Baume copper and quicklime 500 grams each, every two weeks or so spray 1 time. To control other diseases, omethoate 1000 times and methamidophos 800 times formaldehyde 1605 emulsion 1000 times can be selected to ensure the healthy growth and development of plants and lay the foundation for early fruiting.
