In the winter, when managing loofah, don't overdo it. If the pursuit of production, forced to promote propolis, it will inevitably cause imbalance in nutrient distribution, stems and vines will not be due to adequate nutrition and weak, slow growth, leading to premature plant failure, yield decreased. Therefore, in the management of deep winter loofah, it is necessary to pay attention to regulate the balance between vegetative growth and reproductive growth, and to maintain a good stem. Reasonable to stay in the melon season, loofah plant growth is slow, can change the high temperature season "2 to 3 leaves leave a melon," the way to stay in the melon as "5 to 6 leaves leave a melon." Timely watering, fertilizing, and injuring roots or underdeveloped roots, and the insufficient supply of water and nutrients for plant growth are also important reasons for the thin stems. Loofahs are hi-hot crops. Despite their well-developed root system, the root growth rate is also slowed when the ground temperature is low in winter. Especially when one-time water and fertilizer are too large, it is easy to significantly reduce the temperature of the ground and cause the roots to be damaged, which in turn causes the vines to grow thin and grow slowly. Therefore, the principle of "water pouring under the membrane and intensively applying root fertilizer" should be applied for watering and fertilizing. Fertilizer should be rooted in the roots of high-quality biological bacteria fertilizer, each flush per acre 50 ~ 60 kg, and with a suitable amount of high-quality compound fertilizer. At the same time, after watering and fertilizing, it is necessary to pay attention to the temperature in the closed shed and raise the temperature.
