Detailed Explanation of Cucumber Vine Lowering Techniques and Operation Methods
In the process of growing cucumbers, lowering the vines is an essential task. The main purpose of lowering the vines is to distribute the leaves evenly, maintain a reasonable position for light exposure, improve photosynthetic efficiency, and extend the fruiting period. So how should cucumbers be lowered? Let's take a look together.
1. Timing for Lowering the Vines
To carry out the vine lowering work, the first thing is to determine the timing. Cucumbers grown in greenhouses are all cultivated with hanging vines. Generally speaking, once the top of the cucumber exceeds the wire, the vines can be lowered. In the early morning and evening, the temperature is lower, and the cucumber vines are hard and brittle, making them very easy to break. At noon, when the temperature is relatively higher, the vines are relatively soft, so vine lowering can be carried out.
2. Height of Vine Lowering
Many people, in order to save effort when lowering the vines, tend to lower them too much. This results in too few leaves remaining on the plant after lowering, which seriously affects cucumber growth. Generally, after lowering, the plant should retain at least 15 leaves to be appropriate, so that there is sufficient nutrient synthesis. Actually, lowering the vines too much during the vigorous growth period does not have much impact, because this is the optimum temperature for plant growth and recovery is very quick. However, this cannot be done in the later stages of growth.
3. Method of Vine Lowering
Vine lowering can be carried out together with leaf removal. First, remove leaves so that the plant retains 15 leaves, then untie the binding rope at the bottom of the cucumber plant. This way, the main vine of the cucumber will slide down. Then coil the main vine neatly round by round, and after lowering it to the appropriate height, use a rope to secure the main vine.
4. Strengthen Management
When lowering the vines, spray chlorothalonil per mu to prevent wounds from being infected by pathogens. In addition, it should be noted that to obtain a longer growth period and higher yield, sufficient nutrients need to be supplied, so as to ensure sustainable cucumber production. Therefore, after lowering the vines, fertilizer and water management should be strengthened to ensure flowering and fruiting, and this should not be neglected.
