Bitter gourd, as its name implies, tastes bitter, but although bitter, it is also a kind of melon vegetable that many people like to eat very much. With the coming of winter, the management of bitter gourd is becoming more and more important. Winter will have a certain impact on the growth and development of bitter gourd, so today Bian Xiao has brought you the technical points of bitter gourd management in winter. Let's have a look.

1. Temperature control

The temperature in winter is very low, so the primary management of bitter gourd in winter must control the temperature well. Bitter gourd likes warm and light. Bitter gourd is very sensitive to temperature changes during melon planting, and the daytime temperature should be controlled at around 28 degrees, which should not be too high. The temperature at night should be kept at about 65438 02℃. If it is lower than 12℃, it will hinder the flower bud differentiation of bitter gourd, resulting in the decline of flowering and fruiting rate of bitter gourd and uneven growth of bitter gourd. In winter, while ensuring the temperature, there is also proper ventilation and light transmission to ensure bitter gourd.

2. Picking leaves in Qingyuan

Generally, bitter gourd has been harvested after winter, so it is necessary to do a good job of clearing the garden. First, remove the old leaves, insect leaves and other leaves that grow on bitter gourd vines, and then take the fallen melon out of the melon garden and burn it deeply. Control the spread of germs and prevent diseases and insect pests caused by germ activities next spring. Do a good job of disinfection, soil preparation and deep ploughing, destroy the overwintering sites of pests and diseases and bacteria, improve the cold resistance of bitter gourd plants and enhance immunity. Reduce the occurrence of pests and diseases, and provide a good growth environment for bitter gourd plants and melons.

3. Water and fertilizer management

When planting bitter gourd in winter, ridge planting should be carried out as far as possible to keep the temperature of bitter gourd, and after planting, fine soil film should be covered to prevent the air humidity in the shed from being too high. Pay attention to the water temperature when watering to prevent frostbite of bitter gourd caused by low water temperature. Drip irrigation is the main method, about once every three weeks. When watering, apply a little compound fertilizer. At this time, fertilization is mainly to promote bitter gourd to take root. Raise soil temperature and promote the growth of new roots. However, we should pay attention to the dosage, not excessive, because the temperature of compound fertilizer is too low, which is easy to cause freezing damage to bitter gourd and affect the growth of bitter gourd plants.

4. Disease control

In winter, the temperature is low, and pests are basically wintering, which will not cause harm to plants. But if there is no mismanagement, it will still be hurt by the disease. The common diseases of bitter gourd in winter are spot disease and powdery mildew, so we should take these two diseases as the general direction when preventing and treating diseases in winter. Regularly use the corresponding prevention and control agents for disinfection, eliminate germs and cut off the transmission route of germs. Then we must do a good job in cleaning the garden, because most of the germs attach to old leaves and fallen melons. Observe the melon orchard frequently, and take corresponding measures in time when finding abnormal situations, so as to find and deal with them early.

The above is a brief introduction to the technical points of bitter gourd management in winter. With the maturity of planting technology, most vegetables can be planted out of season. Bitter gourd is no exception, but these management work must be done well when planting in winter, otherwise it will easily lead to planting failure.
