- 摘要:
- 以西北农林科技大学核桃试验示范站栽培的6年生“强特勒”核桃为试材，以同期栽培的“香玲”核桃为对照，通过物候观测和果实生长动态测定，对比分析了2个核桃品种的果实生长规律，以期为“强特勒”核桃的栽培管理提供参考依据。结果表明：2种核桃果实三径生长量与其生长时间的关系均与Logistic模型高度吻合，回归方程统计检验均达极显著水平；2种核桃果实三径相对生长速率均有4个完全同步的明显峰值，但“强特勒”核桃果实三径相对生长速率的第1和第4峰值出现时间均比“香玲”核桃落后7 d；在果实快速生长期，2种核桃果形指数均呈由高向低的递减过程，但“强特勒”核桃果形指数的递减速度快于“香玲”。
- Abstract:
- Taking 6-year-old‘Chandler’walnut that cultivated from walnut experiment and demonstration stations of Northwest Agriculture and Forestry University as marerials，with ‘Xiangling’ walnut that cultivated at same period as control，through phenological observation and measurement of fruit growth dynamic，growth trend of two kinds of walnut were analyzed，to provide reference to cultivation management to ‘Chandler’walnut.The results showed that，three diameters growth trend of two walnuts had a high correlation with Logistic model，and the statistic test of regression equation reached a significant level；two walnuts diameter growth rate had four synchronized peaks，but the first and fourth diameter growth peaks of ‘Chandler’ walnut were 7 days later than ‘Xiangling’ walnut；in the walnut fast growing period，two walnuts shape index showed a decreasing process，but the decreasing speed of ‘Chandler’ walnut was faster than ‘Xiangling’ walnut.
