How to grow vineyards in greenhouse with good quality?

How to grow good quality greenhouse vineyards? Asking for advice greenhouse planting grapes can increase the price of grapes. However, some fruit growers often do not pay attention to improving the appearance quality of grapes in the operation, which affects the economic benefits of greenhouse grapes. Through several years of planting observation, we found that we should start from the following aspects to improve the appearance quality of greenhouse grapes. 1. Rationally raising temperature after closing shed is the key to improve fruit setting rate of greenhouse grape, and also an important measure to improve fruit cluster appearance quality. However, if the temperature rises too fast, it will affect the late differentiation of grape flower buds, increase the ineffective differentiation of flower buds, and appear scattered clusters. The correct method of warming up is to cover the shed with straw curtain for 5~7 days after buckling the shed, and then slowly pull up half of the straw curtain, so that the temperature in the shed rises to 20℃ in about 10 days to promote the normal differentiation of grape flower buds. Second, inflorescence pruning greenhouse grape inflorescence pruning generally divided into 2 times. The first time after the inflorescence unfolds, the excessive or weak inflorescences are removed in time according to the load condition. For the second time, before flowering, the accessory spikes on the inflorescence and 1/5~1/4 of the tip of the inflorescence were pinched off. 3. Cluster treatment After flowering, the inflorescences should be soaked in 15×10E-6 92 O solution for 3~5 seconds, so that the fruit stalks of grapes can be properly increased to avoid the appearance of particularly compact clusters, which affects the late coloring of grapes. The time of ear arrangement should be carried out after physiological fruit drop, and the fruit grains with poor development and insufficient fertilization should be eliminated to make the ears neat and the fruit grains consistent. 4. Spraying rare earth micro-fertilizer and calcium fertilizer 800 times of rare earth micro-fertilizer solution before flowering, full fruit stage and fruit expansion stage of grape; spraying 100 times of amino acid calcium solution once every 10 days one month before ear maturity. This can increase the sugar content of grapes, make grapes mature earlier, and also promote the thickening of the peel and reduce the cracking of grapes. 5, timely pruning in the first 15 to 20 days of grape maturity, to timely pruning of grapes. Cut off the branches and leaves that are too dense in the shed and affect the light of the ears, improve the light transmittance of the ears, and promote the coloring of grapes. At the same time of pruning, the ears with poor light should be gently reversed to make the ears fully visible. Click to see more grape growing technology Click to see more fruit growing technology
