One, hang vine
About a week after the cucumber is planted in the deep winter, when the plant grows to 3 to 5 leaves, the vines can be hung. When the plant height is about 20 cm, the vines are started around, and the cucumber vines are wrapped around the slings to fix them. Use polypropylene to tear the lower end of the rope and put it on the stem part. The upper end of the rope is wound with a piece of it, and then it is used as a vine. Then it is tied to the thin wire under the ridge film and the vine is led to the sling. "Formed vines. In winter, the twigs of cucumber are luxuriant. There are 6 leaves in the plant. The tendrils start to appear when the tendrils begin to appear. To prevent the vines from reaching the roof of the sheds prematurely, the first 1 or 2 abductions can be taken in the form of "S"-shaped ramifications. Straighten the tie and wait until you tie it, then adjust the vine to "S" shape and tie it straight up. To make “S†shaped vines, adjust the plants to the same size by bending the length of the stems.
Second, pick rolls and male flowers
In conjunction with the vines, the male flowers were removed in time, and the tendrils and lateral branches below the fifth section of the base were destroyed. The collaterals above section 5 may leave 1 melon, leaving 2 leaves in front of melon topping. Only the base lateral branches, tendrils, and flower buds were removed. When the plants grew to the height of the wire, they were picked up. After the main vines were harvested, the side vines were used to increase the yield. For the long-season cultivation of greenhouses or modern greenhouses, the tendrils, lateral branches and flower buds of plants below 1 m (12 to 13 leaves) were all removed, leaving only 1 m of flower buds.
Third, falling and playing old leaves
Remove the melons, bend melons and deformed melons in time, knock out the old yellow leaves and diseased leaves in time, and remove the collaterals that have been harvested. When the plants are full on shelves, when the plants grow to 2 meters (20 to 21 leaves), the old leaves of the stems should be removed in time, and the top buds should be removed when the plants grow to 2.5 meters (25 to 26 leaves). The stems of the main vines have been swept away, and the hanging slings should be opened and released so that the vines will lie on the ground and make room for the continued growth of the plants. According to the growth of the plants, the vines will fall once in a while. General pruning 2 to 3 times a week (play old leaves, side branches, in addition to tendrils, etc.). After the lateral buds grow, it is a key measure to obtain high quality and high yield by using the side vines to hang down around the wire.
Fourth, make reasonable plant adjustments
Plant adjustment plays an important role in maintaining high yields and avoiding abnormal growth. The pruning methods of cucumber generally include single vertical stem pruning, umbrella pruning, single stem pruning and double stem pruning (V-shaped pruning) and the like. The above adjustments should be used flexibly, and no hardships should be applied in order to achieve the goal of high yield, high quality and high efficiency.
