Wine grapes have a short and concentrated flowering period and consume more nutrients. Therefore, the flowering period is a key period of year-round management. Based on the climate characteristics of this year and the actual situation of Dongling Town Wine Grape Base, it is suggested that wine grape farmers should do the following management work:
1. Apply full fruit fertilizer. Fertilization is to prepare for the high quality and high yield of wine grapes. Combined with watering, per acre Shi quality decomposing circle manure 2500-3000 kg, urea 15-20 kg or ammonium bicarbonate 40-50 kg, diammonium phosphate 5-10 kg.
2. Spray boron before flowering. Boron is one of the 16 nutrients necessary for the growth and development of fruit trees. It promotes flower buds to be fertilized and fertilized, avoiding "flowers but not realities" and "reality without fruit". It can spray 1000-2000 times of boron fertilizer solution.
3. Pest control. This period focuses on the prevention and control of anthracnose, blackpox, rachis brown blight and gray mold. In the 2-3 days before flowering, spray 80% spray 600-800 times + 70% thiophanate-methyl 800 times, if pests can be mixed pyrethroid insecticide or diflubenzuron and so on. After flowering, around June 10, an easy-to-use 100-fold solution + Fuxing 8000-fold solution was sprayed. After 7-10 days, it was protected with 1:0.5-0.7:200 Bordeaux mixture.
4. Flowering summer cut. Eradicate useless buds in time, cut off tendrils, eliminate useless sticks, and do a good job of picking the hearts to the auxiliary shoots. The purpose is to control vegetative growth so as to concentrate the supply of nutrients to the fruits; to tie the vines in time to ensure orderly growth of the grapes; , Cabernet Sauvignon, Merlot, per mu produce 1000 kilograms of fruit, elegant incense, white jade Ni per mu produce 1500 kilograms fruit, dredged the position of improper fruit, weak fruit, spike fruit, and timely eradicate the useless vegetative branch , Maintain a reasonable load frame, ventilation and light transmission.
5. New tips topping. At the time of shoot tipping, it is required to take one week before flowering, and the variety with high fruit set rate can be carried out at the initial flowering stage or one week after flowering. For the results of vines in the ear to stay above the two auxiliary shoots, leaving 4 leaves per axillary tip, the remaining auxiliary tip can leave a leaf topping; for extending the vine can leave 10-15 leaves topping.
