【摘要】 为选择适宜鄂西山区栽培的早实核桃品种,分2次共引进21个品种(系)在海拔1200 m、145 m建立比较试验园,调查冠幅、地径、坐果率、单位面积产量指标。结果表明:3年生香玲、元丰、辽宁1号、中林5号、清香、鲁光品种间每公顷产量达到390 kg,差异不显著,5年生树平均每公顷产量643.5 kg,达到国家丰产园标准;5年生云新系列品种自交2号、云新85227号单位面积产量达到国家丰产园标准。更多还原

【Abstract】 In order to select the early-fruiting walnut cultivars(strains) suitable for cultivation at mountain area of Western Hubei, 21 walnut cultivars(strains) were introduced in 2 times, two contrast experimental forests were built at the altitudes of 1200 m and 145 m, respectively. Crown width, basal diameter, fruit setting rate and yield per unit area were investigated. The results show that yields per unit area of 3-year-old Xiangling, Yuanfeng, Liaoning No. 1, Zhonglin No. 5, Qingxiang and Luguang can reach 390 kg/hm2, and no significant difference among cultivars. Average yield per unit area of 5-year-old plants is 643.5 kg/hm2, and has reached the national standard of high-yield walnut orchard. Average yield per unit area of 5-year-old selfi ng No.2 and Yunxin No.85227 in Yunxin serie cultivars reach the national standard of high-yield walnut orchard.更多还原
