一、前言西宁市冬春淡季蔬菜生产主要依靠温室栽培,而温室蔬菜生产燃煤成本高,且室温和地温不足,不能满足喜温蔬菜对温度的要求,常因冻害造成损失。所以,西宁地区冬季生产喜温蔬菜基本未能得到发展。我省地处青藏高原,太阳辐射强,光照时间长,比国内其他地区利用太阳能的条件优越。把太阳能源用于蔬菜温室,以节约或代替部分燃料,这对今后发展我省蔬菜温室
First, the foreword Xining winter and spring off-season vegetable production mainly rely on greenhouse cultivation, and greenhouse vegetable production coal cost is high, and the room temperature and ground temperature is insufficient, can not meet the temperature requirements of temperature-sensitive vegetables, often caused by the loss of frost damage. Therefore, the winter production of Xining winter vegetables basically failed to develop. The province is located in the Qinghai-Tibet Plateau, strong solar radiation, light a long time, superior to other parts of the domestic use of solar energy conditions. The solar energy for vegetable greenhouses, in order to save or replace part of the fuel, which is the future development of our province vegetable greenhouse
