What should be noted when lowering cucumber vines? These key points need to be mastered
Many farmers know that when cucumber plants grow to a certain height, the vines need to be lowered, but some details must also be noted during the lowering process, otherwise it is very likely to cause poor growth after the cucumber vines are lowered. What should be noted when lowering cucumber vines? Let's learn about it together.
1. Before lowering the vines
It is best not to water for 5-7 days before lowering the cucumber vines. This can reduce the water content of the cucumber stem and vine tissues and enhance the toughness of the cucumber vine tissues, so as to avoid breaking the vines when lowering them. Before lowering the vines, the leaves and cucumbers should be removed, so as to prevent the fallen cucumber leaves from becoming a source of pathogens after disease develops and infecting other leaves and cucumbers.
2. When lowering the vines
During the plant growth period, old leaves and diseased leaves at the base can be removed intermittently. Lowering the vines can be done before 10 a.m. on a sunny day or after watering. When lowering the vines, the movements must be gentle. Do not rudely pull hard. Follow the bend of the vine when lowering it, and also follow the bend of the vine when coiling it. Do not bend it forcefully or bend it in the opposite direction, as this can easily cause the vine to break or be twisted. After the vine is lowered to the ground, do not let it directly rest on the soil, and it is even more forbidden to bury it in the soil, so as to avoid forming adventitious roots and losing the significance of grafting.
3. After lowering the vines
Within 5 days after lowering the vines, it is not suitable to water. After that, apply nitrogen fertilizer with irrigation to promote the sprouting of new leaves. At the same time, according to the types of common cucumber diseases, choose the corresponding pesticides for spraying and control. In the days after lowering the vines, appropriately increase the greenhouse temperature to promote wound healing. For the lower part, side branches that sprout should also be removed in time, so as to avoid competing with the main stem for water and fertilizer.
