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.
