摘要
通过对江西农业大学南酸枣种质资源圃的南酸枣实生树和嫁接树进行连续三年全年的物候跟踪观察,研究了在大田栽培的环境下,两种类型南酸枣在南昌地区的生长习性以及物候表现,观察和记录了南酸枣各个物候期的时间和生长情况。结果表明:(1)在2月下旬到3月上旬南酸枣树体开始萌动,然后逐步进入生长期;(2)3月中旬到3月下旬开始展叶,约12 d后达到展叶盛期;(3)开花期集中在4月上旬到中旬;(4)落花后到8月中旬为果实生长发育期:(5)8月下旬果实进入成熟并开始落果,一直持续到11月中旬;(6)10月中旬开始秋叶变色落叶,一直持续到12月中旬落完叶,进入休眠期;(7)实生苗的各个物候期相对要早于嫁接苗。研究结果可以为南酸枣的科学管理和高效栽培奠定理论依据。
Through the annual follow-up observations of seedlings and grafted seedlings of Choerospondias trees in Jiangxi Agricultural University Science Park for five years,the research was conducted to observe the growth habits and phonological features of seedlings and grafted seedlings of Choerospondias,and the Phonological features and growth conditions of Choerospondias trees were observed and recorded.The results showed as follows:(1)the tree began to sprout from late February to early March,and then went into the growth period;(2)the leaf of Choerospondias trees began to sprout from mid-March to late March and achieved the peak days later;(3)the blooming season began in early to mid-April;(4)the fruit development period began from mid-April to mid-August;(5)the fruit began to mature in late August until mid-November;(6)the color of Choerospondias tree leaves began to change in mid-October,and then all the leaves began to fall,until finished falling in mid-December and got into dormancy;(7)the phenology of seedlings was relatively earlier than the grafted ones.The results provided theoretical basis for its scientific management and efficient cultivation.
