The grape planted in that year must have good results as early as possible. In the cultivation and management, the following measures should be grasped: 1. Fertilizer should be applied sparingly. In the growing season of the grapes, fertilization should be applied to the ground to reduce the damage and waste, so as to promote the growth and development of new shoots, and lay a solid foundation for early formation and early harvesting. Technical requirements, from the bud of grape to the end of August to apply a fertilizer once a month, each time each animal and manure urine water and fertilizer 5 kg and 50 grams of nitrogen fertilizer application. If there is little or no rain during July-August, the weeds will be covered around the vines and the soil will be resistant to drought and irrigation. 2, stand and summer scissors. Grapes are creeping climbing plants and they must be erected to capture high yields. Therefore, in the year of planting, it should be set up early. Plants that cannot stand should also be erected with semi-stands to bind new shoots and increase their polarity. However, it must be racked up in winter, otherwise it will affect the growth of the following year. After the grape sprouts, when the new shoot grows to a certain length (about 20 cm), you can choose to leave a stout new shoot as the main branch and erase the rest of the tender shoot. Under good fertilizer and water management conditions, the annual growth of the grapes can reach 4 to 5 meters. In order to promote the development of the auxiliary shoots, the shoots are picked up when the new shoots grow to the height of the shelf, and the shoots are promoted to the tip. At the same time, attention is paid to removing the tendrils. Tendril in production is often neglected by the majority of growers. This is one of the important factors affecting the early end of high yield, because under good conditions of fertilizer and water management, if the environmental conditions are appropriate, the tendrils can be differentiated into flower buds. In winter, branches can be used as backbone branches to shape the plant earlier. 3. Keep loose soil throughout the year. Due to the increase in the frequency of fertilization and the raining of the rain, the soil in the garden is easy to compact, which is not conducive to the growth and development of the plant roots (the grape is a fibrous root system, and the growth and development were not strong in that year). If the soil in the park can be kept loose all year round, the growth rate of technical shoots can be increased by 15-30% compared with general management, which can reduce the harm and occurrence of pests and diseases. 4, pay attention to the prevention and control of pests and diseases. The grape diseases planted in the current year are generally lighter, but the plants planted in winter are not quarantined and disinfected due to external transport. Some grapes have signs of disease, such as blackpox and powdery mildew. Spray control. Powdery mildew can be sprayed with 1000 times solution of thiophanate or 0.5% lime sulfur to prevent other diseases from spraying 160-180 times the equivalent of the formula (500 grams of copper Sulfate and quick lime) or semi-equivalence formula (drug The Bordeaux mixture, which is halved in volume, is sprayed every two weeks or so. Prevention and control of other diseases Optional dimethoate 1000 times, iridescent phosphorus 800 times the formaldehyde 1605 emulsion 1000 times liquid control effect is good, ensure the plant robust growth and development, laying the foundation for early results.
