In order to make the grapes many times a year, mature or delayed, to extend the market supply time, to obtain higher economic benefits, so the grapes were invited into the protected areas from the open. However, due to the limited space for greenhouse grape growth, the quality and yield of grapes are affected. In order to change this situation, the author studied the cultivation techniques of Portuguese and Portuguese protected fields, and considered that the use of dwarf plastic trimming techniques in the protected areas is more suitable for dwarf trees, better ventilation and light transmission, improved quality, and increased yield. . This kind of pruning technique is introduced to everyone for reference.

First, wipe buds colonized after survival colonization, when the buds l-3 cm long, each bud left a reserved, larger and flat bud left, and the rest erased, said wipe buds. When the leaves are to be selected and the shoots grow to 4-5 leaves, the shoots are set. Two shoots near the base are selected for cultivation, and the remaining shoots are removed, and the shoots are called spurs.

2. At the same time as the shoots grow upward, at the same time each leafhopper will grow a secondary shoot. When the secondary shoot grows 2-3 leaves, it will be picked up. When the new shoot grows to 13-l5 leaves, it will be picked up and then picked up. Out of the shoot, leave 3-4 leaves topping, and repeat until the leaves do not fall long.

Third, when the shoots are newly introduced and the new shoots are grown to 30 cm in length, they must be tied in time to prevent wind breaks. Use a rope, a stable or a straw to bind the vines, but leave room for bold growth. When tying the vines, they must also remove tendrils to prevent cross-winding and waste of nutrients.

Fourth, the winter shears are trimmed before they are buried in the cold for 2 weeks, and pruning during the wounding period is strictly prohibited. Before pruning, the result should first be separated from the preparatory branch, resulting in the position of the branch should be higher than the position of the preparatory branch, so as to achieve the purpose of dwarfing the tree. When pruning, leave the new tip on the top of the tree 0.5-1 meters long, cut off all the auxiliary tips, leaving the part called the resulting mother branch; after leaving 2-3 buds on the top of the new shoot, the rest Cut it off and leave part of it called the ready branch.

5. In the spring of the second year, in the second spring, the flower buds are most easily formed at the 5-9 buds of the mother tree, and 1-4 buds at the lower end rarely form flower buds. Even if flower buds are formed, flower spikes should be removed. No spikes are allowed on the preparation branches. Once they are found, they will be removed and only two new shoots will be left. The pruning of these two new shoots is the same as that of the two new shoots of the first year. Results Results on the parent shoot 5 days prior to the formation of flower spikes, shoots were picked at 7-8 leaves above the panicle.

Repeat the above method in the coming year so that the purpose of dwarfing and pruning the tree can be achieved.
