Grapes like a sunny, well-ventilated and dry climate, but potted plants have certain requirements for water, so they must keep enough water in the pot soil. Grapes like fertilizer. In addition to applying quick-acting fertilizer as base fertilizer when changing pots every year, dilute liquid fertilizer should be applied every 7 ~ 10 days during the growing period to grow vigorously. The requirements for soil are not strict, and loose, fertile and well-drained sandy loam is better.

Vines of grapes are composed of main vines, lateral vines, fruiting mother branches, fruiting branches and vegetative branches. There are two kinds of grape buds, one is winter bud and the other is summer bud, both of which are born between leaves. Winter buds (like peas-sized red envelopes) are formed in the same year, but they do not germinate in the same year (but they can germinate and bear secondary fruits after special treatment). In the second year, it becomes a fruiting branch after full development, flowering and fruiting, and becomes a vegetative branch after insufficient development in the second year. When the main branch is denuded, the summer branch will germinate into a secondary branch, but the summer branch will not bear fruit (but the two secondary branches at the top of the branch can bear secondary fruit after special treatment).

Pay attention to the pruning of grapes during the growth period, which can be divided into two types: winter pruning and summer pruning:

1 pair of winter scissors. Prune the branches and vines after the grapes have fallen leaves in winter. There are too many branches and vines, and their weak growth affects flowering and fruit setting. When pruning, the original bearing mother branch can be pruned in a few cases (retaining 1 bud), short branch pruning (retaining 2 ~ 3 buds) and middle branch pruning (retaining 4 ~ 5 buds). This mainly depends on the development of winter buds between leaf axils. Bad vegetative branches should be cut off, and stout ones should be determined according to the development of their leaf axils to winter buds. Part of the old roots of Panqu should be cut off to promote the germination of new roots in the coming year. After pruning, the first pot should be replaced according to the development of plants, and quick-acting fertilizer should be applied as base fertilizer at the bottom of the pot, then the plants should be placed on the pot, new culture soil should be added, the pot should be watered once, and the pot should be placed in the cold room or buried underground to ensure that the roots are not frozen and fully dormant. Can't put it in a warm room. Otherwise, the new buds will sprout ahead of time, which will affect the growth in the coming year.

2 pairs of summer scissors. Include bud smearing, bud removal, pit removal, flower ear thinning, fruit grain thinning, vine removal, secondary branch treatment, etc.

A. wipe the bud. When the winter buds germinate, wipe off the out-of-position and too dense buds by hand. The first time was in the early stage of germination. Mainly to wipe off the vegetable buds and fine buds on the fruiting mother branches. If there are double buds on a node, there is only one thick bud left. The second time was at the beginning of flowering. Only 1 ~ 2 vegetative branches are reserved except a proper amount of fruiting branches, and all delicate branches are cut off, depending on the size of the pot. Remove sprouted branches. The new branches that grow on the roots are called sprouting branches, so they should be cut off. C. remove the tendrils. There are tendrils on every branch, which consumes nutrients in the body and should be cut off once it appears. Pick your heart. When the leaves above the heading of the fruiting branch grow to 65,438+05, only 65,438+00 leaves are left for coring, and then summer buds among the leaves germinate, and 65,438+0 ~ 2 leaves are left for coring by pumping the secondary branches. After coring with the auxiliary tip, pump it for two or three times before coring. E. sparse flower ears, fruit ears and fruit grains. Sometimes two ears will appear on a fruiting branch, and the smaller one should be cut off. When setting fruit, cut off the spikelets at the top. Some fruits are too dense or different in size, so they should be thinned and cut off as appropriate. This can keep the ears developing well. F. branches should be reserved according to the size of the pot. Don't think the more ears, the better. If it exceeds the carrying capacity of plants, it will inevitably lead to falling flowers and fruits. Generally speaking, 1 ~ 2 ears are reserved for 6-inch pots, 3 ~ 4 ears for 10-inch pots and 7 ~ 8 ears for 14-inch pots. G. When the grapes are ripe and picked, they are still in the warm season, and new buds are still sprouting at the top of the branches. In order to ensure the full development of winter buds on branches, all budding new buds should be erased, so as to ensure that the nutrients produced by photosynthesis of large leaves can be supplied to the full development of winter buds. This measure is of great significance to ensure the results of next year.
