“科学的发生和发展一开始就是由生产决定的”。科学试验的成果促进了蔬菜生产的发展,而蔬菜生产的不断发展,又给科研工作提出新课题。拱园型塑料大棚在西宁地区冬季严寒时,由于气温太低,不能生产蔬菜,但此时正是市场淡季缺菜季节。为了进一步解决这个问题,友谊大队于1974年建立了塑料温室,进行冬季蔬菜生产实验,两年的实践说明,塑料温室基本上可收到与玻璃温室栽培蔬菜的效果,而且造价低,容易推广,这为我省保护地蔬菜生产的发展和增加冬春淡季鲜菜的供应,闯出了一条新路。
“The birth and development of science was decided by production from the very beginning.” The achievements of scientific experiments have promoted the development of vegetable production, while the continuous development of vegetable production has put forward new topics for scientific research. Arch plastic greenhouse in Xining winter cold, the temperature is too low, can not produce vegetables, but this time the market is the lack of season off-season vegetables. In order to further solve this problem, the Friendship Brigade established a plastic greenhouse in 1974 to conduct winter vegetable production experiments. Two years of practice show that plastic greenhouses can basically receive the effects of vegetables grown in glasshouses and are low in cost and easy to popularize. This is for the province to protect the development of vegetable production and increase the supply of fresh vegetables in winter and spring off the season, break a new path.
