Answer: The flowering period of the grape is one of the most important stages in the life cycle and annual growth and development cycle of the grape. The management of the flowering period is directly related to the production of the grape in the current year and the harvest of the coming year. Grapes generally enter the flowering period when the temperature is around 20 ° C. It takes about 2 to 3 days to complete the flowering of an inflorescence. The normal flowering period in a region is usually 6 to 7 days. During this period, the growth of the accessory shoots should be controlled to improve the ventilation and light transmission conditions. In the early stage of flowering, in order to adapt to the requirements of tree adjustment, flower spike shaping, and flower and fruit preservation, the fruit growers should loosen the inflorescence before flowering. The method is to leave a spike in the middle of the new shoots. When the quality of the ears can be seen from the flowering period to the flowering period, the weak ears, the secondary ears, the shoulders and the dysplastic ears of the double ears are removed, and the number of remaining ears is determined by the yield per unit area (mu yield), 2000-3000 ears per mu , The flowering period focuses on keeping flowers and fruits.
