How to scientifically care for loofah stems and vines in deep winter?

In deep winter, when managing loofah, do not push too hard for flowers and fruit. If you force flowering and fruiting in pursuit of yield, it will inevitably cause an imbalance in nutrient distribution. The stems and vines will become thin and weak and grow slowly because they cannot get enough nutrients, leading to premature aging of the plant and reduced yield. Therefore, in deep winter loofah management, you must pay attention to balancing vegetative growth and reproductive growth, and take good care of the stems and vines.

Keep fruit reasonably. In deep winter, loofah plants grow slowly, so the high-temperature-season method of "keep one fruit every 2~3 leaves" can be changed to "keep one fruit every 5~6 leaves."

Water and fertilize in a timely manner. Root damage or an underdeveloped root system, and an insufficient supply of water and nutrients needed for plant growth, are also important causes of thin and weak stems and vines. Loofah is a crop that likes high temperatures. Although its root system is well developed, when the ground temperature is low in winter, root growth will also slow down. In particular, applying too much water and fertilizer at one time can easily greatly lower the ground temperature and cause root damage, which in turn leads to thin and weak stems and vines and slow growth. Therefore, watering and fertilizing should follow the principle of watering lightly under the film and heavily applying root-nourishing fertilizer. When applying fertilizer with irrigation, high-quality biological bacterial fertilizer that promotes and nourishes roots should be the main choice, combined with an appropriate amount of photosynthetic nutrient film fertilizer, which can help plants absorb large amounts of light magnetism, light energy, and light. Working skillfully with traditional nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, and trace elements, it can improve the comprehensive fertilizer efficiency of conventional fertilizers and natural fertilizers needed for plant growth, achieve off-season cultivation, and lower cultivation costs in green, pollution-free agriculture. At the same time, after watering and fertilizing, attention should be paid to closing the greenhouse to raise the temperature and increase the ground temperature.
