摘 要:选用7年生密植园帅枣新品种为试材,对帅枣和对照枝条、果实生长发育动态、产量和品质进行比较研究,以期为帅枣优质丰产栽培提供理论依据。结果表明:年周期中,帅枣系品种枝条果实生长量大,生长曲线均服从logistic生长模型,斜率均高于对照;7月上旬至9月上中旬为子叶与果实快速生长期,帅枣1、2、3号果肉增长量(占总质量)分别为70.70%、69.14%和71.87%,对照果肉增长量占70.74%;帅枣系品种与对照的生长差异主要体现在这一时期,这是优质、丰产栽培的生理基础;帅枣1、2、3号平均单果质量分别为23.60、22.80、25.20 g,分别比对照提高了57.3%、52.0%和68.0%,是木枣的大果优质变异新品种。平均单株产量为4.00~4.40 kg,丰产稳产,较好地保持了木枣的丰产性和适应性,经济效益比木枣番了一翻。The growth of shoots and fruits, yield and quality of three varieties were compared using 7-year-old densely planted Ziziphus jujuba serial cultivars "Shuaizao" as experiment materials, in order to provide theoretical basis for high yield cultivation. Results show that the growth increments are high for branches and fruits of Z. jujuba serial cultivars "Shnaizao" during the whole year. The growth curves for shoot and fruit obey the logistic growth pattern, and the slopes of the curves are larger than that of the check "Muzao". The quick growth period of cotyledon and fruit is from early July to early to mid September, in which the ratios of flesh increment to total weight of fruit for the three "Shuaizao" cultivars are 70.70%, 69.14% and 71.87% respectively, and that for the check is 70.74%, which indicates that the growth difference between '" Shuaizao" cultivars and the check is mainly embodied in this growth period. Early July to early to mid September is a key period for good quality and high yield cuhivation. The average fruit weights of" "Shuaizao" cultivars are 23.60, 22.80, and 25.20 g respectively, which increased by 57.3%, 52.0% and 68.0% compared with the check. The yield of a single plant ranges from 4.00 kg to 4.40 kg. The " Shuaizao" cultivars maintain a high and stable yield and adaptability, and the economic benefit is doubled.
