A reasonable temperature rise after a reasonable temperature rise is the key to improving the fruit set rate in the greenhouse, and it is also an important measure to improve the appearance quality of the ear. However, if the temperature rises too quickly, it will affect the late differentiation of grape flower buds, which will increase the ineffective differentiation of flower buds and lead to the occurrence of confusing ears. The right way to increase the temperature is to use a straw shack for 5 days to 7 days after the shed, and then slowly pull up half of the turf, so that the shed temperature rises to 20°C in about 10 days, prompting the grape flower buds to differentiate normally.
Inflorescence pruned grapevine pruning is generally performed in two separates. The first time after the development of the inflorescence, the excessive or weak inflorescences were removed in time according to the load. The second time before flowering, the spikes on the inflorescence and the tip of one-fifth to one-fourth of the front of the inflorescence were removed.
Spike treatment After the grape has bloomed, it is necessary to soak the inflorescence with 15 PPM of 90% solution for 3 seconds to 5 seconds so that the stalks of the grapes can be properly grown and the particularly compact fruit spikes can be avoided, affecting the later coloration of the grapes. The time for ear preparation should be performed after physiological fruiting, eliminating stunted and insufficiently fertilized fruit, so that the ear is neat and the fruit is consistent.
