蕹菜,又称通心菜、空心菜、竹叶菜。原产热带雨林地区,性喜高温潮湿不耐寒,在我国南方普遍作为夏、秋蔬菜进行栽培。在冬春季,深圳地区利用塑料大棚进行保温,能生产出反季节蕹菜,而且品质更优于夏秋季。这是因为塑料薄漠复盖后的大棚,棚内日平均气温比棚外高2.8-5.3度,地温高5.1- 6.9度,即使在阴雨天气时,日平均气温比棚外也高2.6-3.4度,地温高4.l-5.5度。棚内的小气候环境适合了蕹菜的生长。同时通过人工调节温湿度和肥水,使蕹菜处在最佳的生长环境,达到早熟、高产、优质等生产目的。
Ipomoea, also known as pasta, spinach, bamboo leafy vegetables. Originally tropical rain forest areas, sexual hi hot and humid not cold, in southern China generally as summer and autumn vegetables for cultivation. In the winter and spring, the Shenzhen area uses plastic greenhouses for insulation, which can produce anti-season cucumber, and the quality is better than that in summer and autumn. This is because the plastic thin desert after the cover of the greenhouse, the shed average daily temperature higher than the shed outside the high 2.8-5.3 degrees, the ground temperature 5.1- 6.9 degrees, even in the rainy weather, the average daily temperature higher than the shed 2.6-3.4 Degree, high temperature 4.l-5.5 degrees. The microclimate environment within the shed is suitable for the growth of Japanese laver. At the same time, by manually adjusting the temperature and humidity and fertilizers, Brasenia schreberi in the best growing environment, to premature, high yield, high quality and other production purposes.
