The spring breeze warms up, and now the greenhouse grapes have entered the heading, flowering and fruiting period, and the fruit farmers in the planting bases of Zhelin Town are busy pruning the flower spikes and arranging the branches to lay a good foundation for harvesting high-quality grapes.
Walking into the grape planting base located in Qiansheng Road, Nansheng Village, Zhelin Town, there is a scene full of vitality in the greenhouses, with green grape vines climbing all over the tree frames, and soybean-sized fruits hanging among the green leaves, which is particularly attractive. Zhang Ling, the person in charge, is shuttling between the vines to thin flowers and fruits to ensure a bumper harvest of grapes this year.
"At present, the main work is to thin the grapes, fertilize and water them, so that the grapes will have more uniform particles, higher sugar content and better taste when they are ripe. Zhang Ling introduced while pinching off the excessively long vine buds.
It is understood that in grape planting, the flowering and fruit setting period of grapes is a critical period for grape management, which plays a decisive role in the annual harvest. In April, the temperature rises, the grape branches and buds enter the stage of rapid growth, thinning flowers and ears is the most important part of grape management at this stage, timely treatment of too tall vines, too dense fruit ears, can avoid vines and branches "compete" for nutrients in the grapes themselves, reduce unnecessary nutrient consumption, but also determine the quality and yield of grapes that year.
"For each vine, 6 to 8 ears of fruit are the most appropriate, too much will affect the fruiting and size, and the grape ears should be pruned according to the 'umbrella' shape, decreasing from top to bottom, with 40 to 50 grains per ear. Zhang Ling has been planting grapes since 2006 and has a wealth of experience in grape planting, she said as she showed a bunch of fruit ears that had just been thinned, "Early thinning can make the fruit set tighter, so that the grape spikes are neat and evenly grained. ”
At the same time, in order to ensure that the fruit accumulates sugar and needs a large amount of water and nutrients, the base is also equipped with a complete water and fertilizer management system, which can be applied in time after each fertilization to ensure sufficient water supply and suitable soil moisture.
It is reported that this year, more than 15 acres of grapes have been planted in the Qianshenglu base, and nearly 100 greenhouses have been planted, including summer black, drunken golden incense, rose incense, Jufeng, Qingwang (sunshine rose), Muscat and Yongyou No. 1 grape varieties. "The grapes are insulated by plastic film to raise the temperature in advance, so that the grapes can bud and bloom earlier. Greenhouse grapes are on the market almost a month earlier than open-field grapes, and they are expected to be available in mid-June, and open-field grapes will be available in large quantities in mid-July.
