摘　　要：为研究避雨栽培对枣光合特性和品质的影响,以‘李府贡枣’为试材,露地栽培为对照,避雨栽培为处理,测定环境因子、光合指标的日变化、叶绿素含量及果实品质。结果表明:避雨条件下,光照强度和净光合速率显著低于露地;叶绿素含量上升,叶绿素a/b比值降低;枣果着色较好,可溶性总糖较露地高10%,单果重及纵横经明显降低;裂果率低于5%,露地栽培为50%~60%。避雨栽培显著提升枣果内在和外观品质,降低裂果率。In order to analyze the effect of rain-shelter cultivation on the quality and photosynthetic characteristics of jujube,taken’LifuGongzao’as the test material and open-field cultivation as the control,the environment factors,photosynthetic indexes,chlorophyll content and fruit quality were investigated.As results,as compared with the open-field cultivation,in the condition of rain-shelter,light intensity(PAR)and photosynthetic rate(Pn)were significantly decreased,the content of chlorophyll was increased,while the ratio of Chla/Chlb was lower.In the rain-shelter conditions,the fruits had better color,and the total soluble sugar was 10%higher than that in the open-field,but the longitudinal diameter and traverse diameter of fruits and single fruit mass were obviously reduced;the fruit cracking rate was below 5%,while which was 50%-60%cultivated in the open-field.In conclusion,the results suggested that rain-shelter cultivation could increase the quality of fruits and reduced the fruit cracking rate.
