Latest Detailed Guide to Winter Management Key Points for Bitter Gourd
Bitter gourd is a kind of fruit vegetable that many people like, and it has a planting area of all sizes in our country. With the arrival of winter, the management of bitter gourd should also be taken seriously. Winter temperatures are relatively low, which still has a certain impact on the growth and development of bitter gourd. Below, let us take a look at the key points of winter management for bitter gourd.
1. Temperature regulation
Winter temperatures are relatively low, so the first thing to do when planting bitter gourd in winter is to control the temperature. Bitter gourd likes warmth and light. During the fruit-setting period of bitter gourd, bitter gourd is relatively sensitive to temperature changes. During the day, the temperature should be controlled at around 28 degrees, and it should not be too high. At night, it should be kept at around 12 degrees. If it is lower than 12 degrees, it will hinder the flower bud differentiation of bitter gourd, causing the flowering and fruiting rate of bitter gourd to decrease and the growth of bitter gourd to be uneven. Therefore, while ensuring the temperature in winter, timely ventilation and air exchange should also be carried out to ensure the normal growth of bitter gourd.
2. Clearing the garden and removing leaves
After the beginning of winter, the bitter gourd has already been fully harvested, so we need to do a good job of clearing the garden. First, remove all the old leaves, diseased and insect-damaged leaves and other leaves on the vines, then gather the fallen flowers and fallen fruits and burn them in a centralized manner in the bitter gourd garden or bury them deeply. Control the spread of pathogens to avoid pathogens causing diseases and insect pests in the spring of the next year. Do a good job of disinfection, deeply plow the soil, destroy the overwintering places of pathogens, improve the cold resistance of bitter gourd, and enhance immunity.
3. Fertilizer and water management
When planting bitter gourd in winter, try to cultivate on ridges, as this can keep bitter gourd warm. After planting, cover with fine soil and plastic film to prevent the air humidity in the shed from becoming too high. When watering, pay attention to the water temperature to avoid frost damage caused by water temperature being too low. Watering should mainly be done by small drip irrigation, about once every three weeks. When watering, combine it with applying a small amount of compound fertilizer. At this time, the purpose of fertilization is to promote the rooting of bitter gourd. Increase the ground temperature and promote the growth of new roots, but pay attention to the amount of fertilizer applied and do not apply too much, because when the temperature of the compound fertilizer is too low, excessive application can easily cause frost damage to bitter gourd.
4. Disease control
Winter temperatures are low, and pests basically overwinter and will not cause much harm to the plants, but if management is poor, they will still suffer from diseases. The diseases promoted in winter include leaf spot disease and powdery mildew. When controlling them, focus on these two, then do a good job of clearing the garden. Observe the bitter gourd garden frequently, and take corresponding measures in time after discovering abnormal conditions. Early discovery and early treatment.
