Grape planting techniques: how to manage summer grapes?

How to manage summer grapes? Please give guidance on how summer grapes can be managed with reference to the following methods: 1. Branch management. 1. The new shoots of grape seedlings raised by wiping branches and cuttings grow to 40 ~ 50 cm in mid-July. Some seedlings have several new shoots or several secondary shoots of a new shoot, which must be wiped in time to leave a strong new shoot. 2. Pick the heart when the new tip of the grape seedling grows to about 50 centimeters. The secondary tip produced after heart extraction is erased except for the one at the top. When the apical accessory tip grows to 6 leaves, leave 3 leaves to pick the heart. All regenerated tips on the secondary tip are erased. 3. The new shoots on the seedlings of high-grade grape varieties can be put up to 1.0ml 1.5 meters, and such seedlings must be tied up. A bamboo pole can be inserted between the two rows of seedlings every 3mur4 meters, and the thin iron wire or nylon rope can be pulled up. Pull a line on each of the two bamboo poles. Tie two rows of seedlings to the wire or nylon rope between the bamboo poles. If the seedlings are sparse, a bamboo pole can be tied to the new shoots of each seedling. Second, the management of water, fertilizer and soil when the seedlings grow to 8 leaves, apply 15,000,000 kilograms of urea per mu, and apply it again 15 days later, usually three times. Topdressing outside the root is divided into 2 times, 0.5% urea is sprayed in summer, 0.3% potassium dihydrogen phosphate is sprayed in autumn, and each is sprayed twice. Before the grape cuttings germinate, they are usually watered every 7 days. After the new shoot grows to 10ml / 20cm, water is watered every half a month. Wait for the new tip to grow to 30ml 40cm, water once every 20 days, good soil moisture will not be watered. If the seedlings are not out of the nursery before winter, they should be watered for the winter. Each topdressing should be watered immediately. When the new shoot grows to 8 leaves, the hybrid seedling can be recognized and pulled out by root. Different grape varieties should be marked with bamboo slices and inserted among different varieties. Grape seedlings should not leave the nursery immediately after falling leaves, because this is the process in which nutrients continue to be stored in the roots. It is more appropriate to come out of the nursery before and after Lesser Snow. Nursery beds are covered with plastic film, generally do not need ploughing, pull out weeds. Remove the ridges and weeds on both sides after each watering. Grape seedling diseases are mainly downy mildew and black pox, and the main pests are cotton bollworm, beet armyworm and grape armyworm. Spraying can be used for comprehensive control of diseases and insect pests. When the seedling grows to 8 leaves, start spraying, you can spray 50% carbendazim 500 times, and after half a month, spray 80% spray 600 mol 800 times. After the seedlings are coring, spray Bordeaux liquid of 1-0. 7-0. 7-200 Bordeaux. If downy mildew is found, spray 78% Cobo 600 times solution, or 80% ethyl phosphorus aluminum 300 times solution 500 times. In autumn, Bordeaux liquid is sprayed mainly with Bordeaux solution of 1 / 1 / 1 / 180 or 1 / 1 / 1 / 5 / 1 / 180.
