光质和温度对日光温室番茄生长发育及产量品质的影响

目的]为红色环照牌光合膜的推广提供科学依据.方法]以兵马佣超大988F1番茄为供试品种,以红色环照牌光合膜为试材,白色PE膜为对照,研究了河西地区日光温室通过红色环照牌光合膜改善的光质和温度对冬春茬口栽培膜式下对番茄生长发育、产量、品质的影响.结果]红色环照牌光合膜更有效地调控气温,增加根际温度,提高红光透过率,延长光合作用,番茄平均产量提高1 6.3％,可溶性固溶物提高5.8％,株高平均增加17.8％,主茎蔓增加9.5％,叶片数增加7.4％,花序个数增加13.2％,平均节位数增加8.5％,结果数增加8.2％.结论]在冬春茬口上,番茄生长的最适气温在27℃左右.红色环照牌光合膜更有效地保证夜间温度预防冷害.

Effects of Red Light and Temperature on Growth,Yield and Quality of Tomato in Greenhouse

Objective ] The research aimed to provide the scientific basis for the popularization of the red ＂HuanZhao＂. photosynthetic membrane Method ] Using ＂ Bing ma yong chao da 988F1＂ tomatoes as material, using Red ＂HuanZhao＂ photosynthetic membrane as materials and white PE membrane as control, the effects of red ＂HuanZhao＂ photosynthetic membrane and temperature on crop growth, yield and quality of tomatoes cultivated in Hexi Area greenhouse were studied. Result] Red ＂HuanZhao＂ photosynthetic membrane effectively regulated the temperature, increased the temperature of the root zone, and improve the red light transmittance and prolonged photosynthesis. Tomato production increased by an average of 16.3% ,soluble solid solution increased by 5.8% ,average height increased by 17.8% , main stem increased by 9.5% , leaf number increased by 7.4% , the number of inflorescences increased by 13.2% , the average node order increased by 8.5% , and fruit number increased by 8.2%. Conclusion ] In the winter and spring cultivation, optimum temperature of tomato growth was around 27 ℃ , while the red ＂HuanZhao＂ photosynthetic membrane could more effectively ensure preventing nighttime temperatures from cold damage.
