1, seedling management
Cucumber seedlings grow rapidly, especially those cultivated in nutrition bags or bowls. In order to prevent excessive growth, water and temperature should be strictly controlled, and seedlings should be gradually exposed to the open air after digging. The temperature should be controlled at 20-25 degrees Celsius during the day and around 10 degrees Celsius at night.
At the same time, it is necessary to strengthen the management of fertilizer and water, water seedlings with compound fertilizer every 5-7 days, add metalaxyl or metalaxyl aluminum copper to prevent the harm of root rot, and spray wine with Bordeaux solution every 4-5 leaves to prevent powdery mildew and white rust.
Planting techniques of Hami melon
2. Tian Tuan management
In the early stage of seedling transplanting or direct seeding, it is necessary to hoe and plough diligently to promote root system development. Root cutting diseases all come from root system, which is underdeveloped, thin and relatively serious.
In the future, it is necessary to combine irrigation, intertillage, ridging and fertilization and strengthen management as the theme.
At the same time, it is necessary to prevent and control pests and diseases in time, with emphasis on downy mildew, powdery mildew, white rust and root rot.
It is suggested to use more ecological pesticides such as Bordeaux mixture, and pay attention to using biological pesticides such as bt emulsion to control leaf miner.
When the cantaloupe grows to 3-5 leaves, it should be peeled and trimmed.
-Generally, "Zi Man" and "Sun Man" are adopted to make cantaloupes listed one after another.
When Hami melon grows to 5-6 leaves, topdressing should be done in time, and 20-30 kg compound fertilizer can be applied per mu to promote the growth of roots, vines and young melons. At the same time, irrigation should be carried out every 3-5 days to keep the soil moist.
3. Take the lead
The main vine of Hami melon rarely has female flowers, and the melon is produced by the vine and the sun vine. Most vines produce female flowers at 1-2 nodes.
Therefore, timely coring is the key technology of melon cultivation.
After planting cantaloupe, when the main vine grows to 4-5 leaves, it should be topped and pitted in time. After secondary tendrils occur, 2-3 strong secondary tendrils should be selected, and other weak secondary tendrils should be cut off.
When the selected vine has 5-6 leaves, pick the heart again, select 3 positive vines on the vine, and cut off other weak positive vines.
After Sun Man sat on the melon, he left two leaves to pick the heart from the melon and paid attention to removing the deformed melon.
Distribute vines and sun vines evenly, and press clods on the vines.
Old leaves and diseased leaves were cut off and taken out of the field.
