Picking leaves and falling vines is an important measure in the management of cucumbers in greenhouses. Coordinating the relationship between the two is a guarantee of harvesting of winter cucumbers. The lower leaves must be removed before falling. In general, the lower leaves have been aged before falling, photosynthetic enzymes and other functions have been reduced, and the photosynthetic rate has decreased. After falling, the upper leaves fall to the bottom, resulting in the overlapping of the upper and lower leaves. The organic nutrition produced by the photosynthesis of the lower leaves is not enough to meet their own needs and cannot provide nutrients for the growth of the plants, losing the necessity of existence. In addition, if the leaves are not picked up, the lower branches and leaves will be more likely to cause wounds. After picking the leaves and picking the leaves, this time before picking the leaves, the air circulation in the surface environment is poor, the humidity is high, and there are wounds formed by falling vines. The pathogens are easy to infect the disease, resulting in the occurrence of diseases. Therefore, before the cucumber falls, the lower leaves must be removed in time, and the wounds should be dried before they fall. In order to prevent bacteria from invading the injured stalks, chlorothalonil can be mixed with chlorothalonil to prevent disease after spraying. When the leaves are picked, the leaves at the bottom of the plants should be picked up by stages. Do not pick them clean. When the old leaves were removed, only 1-2 leaves were picked at a time. After picking the leaves, there were 13 or more functional leaves of the cucumber, so that no obvious growth stagnation occurred. In winter, the temperature in the shed is low, and the cucumber grows slowly. Falling vines suppress the apical dominance of the growing cucumber. Therefore, each time in the deep winter season, the vine should not exceed 50 cm, and the cucumber should be gradually grown to over 1.6 meters.
