Open field cultivation

Open field cultivation has a large area in North China. Generally, seedlings are cultivated in windbreak impotence or plastic sheds in mid-March, planted in open fields in mid-to-late April, and harvesting begins in early June. This cultivation method is more than 20 days in the morning compared with winter melon, which supplements the blank period of winter melon supply, and the economic benefits are significantly higher than winter melon cultivation.

The nursery period of open field cultivation is from March to April, and the outside temperature rises day by day, but occasionally frost may appear at night. Therefore, the temperature management should be strengthened in the seedbed, pay attention to ventilation and cooling during the day to prevent excessive temperature, and avoid frost damage at night. 7 to 10 days before planting, gradually increase the amount of ventilation, and then remove the plastic film, so that the seedlings are exposed to the ground and enhance their adaptability. Other matters of seedling management are the same as those of early maturing spring.

When the seedling age is 30 to 35 days, 3 to 4 true leaves, and the external night frost is out of date for colonization. Field management etc. refer to early spring maturity cultivation.
