因外界条件关系、蔬菜保护地栽培在大兴安岭地区具有特殊意义。黄瓜保护地栽培是我区主要的生产途径。黄瓜生育季节喜欢温暖湿润,忌冷凉。虽然是短日照作物,经多年栽培驯化对长日照反应并不敏感。可利用白天高温长日照优势提高太阳光能的利用率,加快生育进程。提高光合强度,使有机物的合成加快,大幅度地增加光合总产量与作物同化物质的累积量。夜间温度低,呼吸作用减弱,消耗养分少,就是说在新陈代谢过程中是高收入低消耗。理论上有创高产的可行性,实践上高产典型也屡见不鲜。
Due to the external conditions, cultivation of vegetables in the Greater Xing’an Mountains is of special significance. Cucumber cultivation is the main production area of my area. Cucumber growing season like warm and humid, avoid cold. Although short-day crops, after years of cultivation and domestication on the long-day reaction is not sensitive. The advantages of daytime high temperature and long sunshine can be used to improve the utilization of solar energy and speed up the process of reproduction. Improve photosynthetic intensity, accelerate the synthesis of organic matter, greatly increase the total photosynthetic yield and crop cumulant accumulation. Low night temperatures, reduced respiratory effects, low consumption of nutrients, that is, in the metabolic process is high-income low-consumption. In theory, the feasibility of a high yield, in practice, high-yield typical are not uncommon.
