In order to enhance the competitiveness of the grape market, it has become the consensus of growers to promote the use of bagging technology on grapes, but how to maximize the effectiveness of bagging? Before bagging, prepare flower spikes 1 week before flowering, remove spikelets and spikes from 1 to 8 spindles at the base of spikes, and spend less or less on flower spikes; spend 1/4 of the spikes before flowering and set fruit for 2 weeks. Sparse grains start immediately after the fruit is stable, and end before the onset of the rainy season. Bagging method When the bagging is done, the paper bag is first stretched by hand so that the entire bag is bulged, and then the whole ear is fully inserted into the bag from bottom to top, and then the bag mouth is retracted to the handle, and the side sealing wire is used. Hold tightly. However, a 1.0-1.5 cm paper bag should be left above the sealing wire, and the ear must not be rubbed by hand. Bags can be bagged and bag harvested after bagging; red varieties can be bagged about 10 days before harvest to promote good coloring. However, if the color of the inside of the bag is very good and it is close to the best color of the product, you don't need to go to the bag, otherwise it will make the purple deeper and the coloring too much.
