First, the seedling spring, winter melon production should choose short vine type early maturing varieties, in mid-December to nurse seedlings. The temperature during the nursery is 25-28 ° C during the day and 13-15 ° C during the night. If this temperature is not reached, warm it with a geothermal wire or water heater. In order to ensure full root colonization, it is required to use 9 cm × 9 cm of nutritious soil to raise seedlings. Planting reached 50 days of seedling age, 5 leaves of the leaves, stem diameter of more than 5 mm, plant height of 18 cm.
Second, the planting time is in the middle and late February, and the land preparation should be done before planting. Ditch the ditch according to the line spacing of 70 cm, choose the sunny weather, set the seedlings in the ditch and then water the water. After the water is finished, seal it into a single ridge. The height of the ridge is 15 cm and the width is 25 cm. The suitable planting density is about 2500 per mu.
Third, the management of the greenhouse after the planting of the light melon must be framed and cultivated. When the frame is set up, it is required to be a row, with a bamboo pole or a wooden stick to form a "door"-shaped flat frame with a height of about 80 cm. The frame is solidly tied with a wooden pole or a small bamboo pole. In time, hit the lychee outside the main vine, leaving a main vine. When the vines are put on the shelves, let the vines cross on the ground and put them on the shelves. That is, when a row of melons climbs to the second row on the ground, the vines are put on the shelves. The second row is on the ground when climbing to the first row, so that the melons are just opposite. It is relatively neat and easy to manage. Always pruning, prevent bulls and keep the main vine advantage. The temperature management before the cassation should be proper, 28-30 °C during the day and 13-15 °C during the night.
In the solar greenhouse, the melon is produced in the early spring, and the second melon is generally selected, at the 10th to the 12th leaves. During normal growth, the open part of the female flower is just on the cultivation raft. After flowering, it is necessary to adopt the dual treatment measures of hormone and artificial auxiliary pollination to ensure stable fruit setting, and grow faster and get listed early after fruit setting. The indoor air humidity is high and the temperature is high. After the flower is opened, the anther powder is slow. Therefore, after the second melon female flower is opened, 100 ppm of 2,4-d is used, and the stalk is smeared at 8-9 am. After 10 o'clock, the anther is cracked and the powder is scattered. At 11 o'clock, artificial pollination is held in time, and each pollination is carried out. 1 fruit, the rest should be removed in time. After the fruit is placed, the temperature is 30-32 ° C during the day and 15-18 ° C at night.
After the melon is sitting on the melon, if the water and fertilizer are timely, it will be available in 25-28 days. About 50 grams of young melon (such as large eggs) should be timely watering and topdressing, 25 kg of urea per acre when watering, choose 8-10 days after sunny weather and then watering and topdressing 1 time. Prevent water from flooding when watering, so as not to cause water melon to cause melons. Increase the amount of air released after watering to prevent excessive humidity and cause disease. The temperature of the expanded melon is 30-35 ° C during the day and 15-18 ° C during the night. In order to reduce nutrient consumption, the lower old leaves should be removed in time.
When the first melon is harvested in late April, the water management will be strengthened to promote continuous fruiting.
