Cucumber growing to the middle stage is the high yield period of cucumber production, and it is the high quality period of cucumber quality. However, at this time, the top of the guava vine has exceeded the bracket and is bent, the apical dominance is inhibited, and the whole cucumber begins to enter the recession period. When the period begins to decline (lower vines), the inhibition of the top dominance can be eliminated and the production period can be extended. The specific operation is as follows:
1, the photosynthesis of the bottom of the melon vine with weak yellow leaves, old leaves, diseased leaves knocked out and out of the field to prevent diseased leaves from infecting other plants. Then the vines are dropped, and the height of the vines is suitable for the last leaf to reach the ground. At this time, each vine should leave more than 15 leaves.
2, when falling vines should pay attention to fall into the bottom of the stent, within the stent, to prevent melons from getting hurt.
3. Fall time should be selected between 10:00 am and 5:00 pm. It is not easy to break or sprain. In the morning, evening, cloudy days, or when the rainfall is just beyond the limit, it should not fall.
4. Beginning with the second fall, it is necessary to adopt vine pressure measures and follow the pressure with the waves. The specific approach is: Select the blade growth point near the bracket to bury it in the soil. About half a month, the growth point will grow. Roots to facilitate more plants to absorb water and fertilizer.
5, pay attention to top dressing, watering, pest control.
