Key points of muskmelon seedling management: melon water and fertilizer management, greenhouse melon seedling pest management

Muskmelon has always been a favorite fruit, its planting area has gradually expanded in recent years, and in order to achieve high yield, it is necessary to do a good job in the seedling management of muskmelon. So how to manage the melon seedling stage? Let's get to know it.

1. Temperature management

Muskmelon seeding branch seedlings unearthed is a higher requirement for temperature, appear to keep the seedbed temperature between 25-30 degrees in order to ensure the smooth emergence of seeds. Before seedling emergence and cotyledon expansion, it is necessary to prevent continuous low temperature and high humidity from causing high-foot temple and sudden collapse disease, so we should take good cold prevention measures at night. After exposing the first true leaf, squat seedlings should be well illuminated so as not to grow excessively. Keep the temperature between 26-32 degrees during the day and 12-16 degrees at night. Excessive temperature can enhance ventilation.

2. Water and fertilizer management

There is no need for watering before melon emergence, after emergence, the temperature increases gradually, and the water evaporation of seedlings during growth is large, so it is necessary to replenish water in time to prevent the seedlings from drying up due to lack of water. Watering should be carried out in the morning on a sunny day, and the water temperature should be controlled at 20-25 degrees so as not to cause low temperature and affect the normal growth and development of the root system. When it is found that the seedlings are short of fertilizer, it can be combined with watering and spraying 1-2 times of low concentration potassium dihydrogen phosphate solution, which can quickly supplement the nutrients needed by the seedlings, and stop watering one week before planting to avoid loose soil.

3. Lighting management

In the prospect of seedling growth, under the condition of suitable temperature, the cold protection of late cover should be uncovered early; in the middle stage of seedling growth, ventilation should be paid attention to, and the vents should be closed in time, and the vents should be opened slowly after the seedlings return to normal. In case of high temperature and strong light, you can cover the sunshade net or spray water to cool down at noon to avoid burning seedlings at high temperature and causing seedlings to grow excessively.

4. Pest control

The main diseases of muskmelon seedlings are standing blight, Fusarium wilt, downy mildew, powdery mildew, blight and so on, which are mostly caused by high temperature and humidity environment, so we should pay attention to the field permeability and drain and dehumidify in time after rain so as not to induce diseases. While the main insect pests are aphids and red spiders, avermectin can be used to control, in the control of diseases and insect pests should pay attention to the concentration of agents, spraying time is best around 4: 00 p. M., to spray leaves on both sides.
