摘要
通过对早实核桃轻剪、中剪、重剪和长放几种修剪方法的研究,探讨了不同修剪强度对成枝长度、枝条粗度、萌芽率、成枝力的影响。结果表明:轻剪、中剪、重剪比长放的成枝长度增加3.60～40.52cm,粗度增加0.19～0.69cm;长放的成枝萌芽率提高了0.15%～0.25%,成枝力提高了0.11%～0.22%。
Different pruning techniques, including light cutting, moderate cutting, heavy cutting, and shoot releasing, and their effects on budding rate, .branching rate, length, thick of precodty walnut were studied. The results indicated： 1） Light cutting, moderate cutting and heavy cutting made new branch length rose by 3. 60-40. 52cm, new branch thick rose by 0. 19-0. 69cm, compared to shoot releasing; 2） Light cutting, moderate cutting and heavy cutting made new branch budding rate increased by 0. 15 %-0. 25%, new branch branching rate increased by 0. 11 %-0. 22%, compared to shoot releasing.
