Field cultivation techniques of zucchini

Open field cultivation technology

Open field cultivation is relatively large in North China. Generally, seedlings are raised in the wind barrier Yangqi or plastic shed in mid-March, planted in the open field in mid-late April, and harvested in early June. This kind of cultivation method is more than 20 days ahead of the winter melon market, which fills the blank period of the winter melon supply, and the economic benefit is significantly higher than that of winter melon cultivation.

The nursery period of open field cultivation is from March to April, the outside temperature is rising day by day, but occasionally frost appears at night. Therefore, the temperature management should also be strengthened in the seedbed, pay attention to ventilation and cooling during the day, prevent the high temperature from being long, and pay attention not to be affected by frost 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. The other matters of nursery management are the same as early maturity cultivation in spring.

When the seedling age is 30 to 35 days, 3 to 4 true leaves, the outside night frost has been outdated for colonization. Field management, etc. refer to early spring cultivation.
