摘要
银杏树产量受多种因素共同影响,其中种植密度是农业管理中较易控制的因素之一。以大马玲银杏1 a生苗为研究对象,试验不同种植密度(10.0×10^(4)、5.0×10^(4)、3.3×10^(4)、2.5×10^(4)、2.5×10^(4)、2.0×10^(4)、1.7×10^(4)和1.4×10^(4)株/hm^(2))对银杏幼苗连续3 a生长表现及产量的影响。结果显示:当银杏幼苗种植密度降低时,银杏树(树龄4.5 a)的地径、树高、侧枝数、叶片数和产量均呈增加趋势,其中种植密度为2.0×10^(4)株/hm^(2)时,银杏树生长量较好、产量较高。
The yield of Ginkgo biloba tree is affected by many factors,among which planting density is one of the factors easily controlled in agricultural management.Damaling Ginkgo biloba 1 a seedlings were taken as the research object,the effects of different planting densities on the growth performance and yield of Ginkgo biloba seedlings for 3 consecutive years were studied.The results showed that when the planting density of Ginkgo biloba seedlings decreased,the ground diameter,tree height,number of lateral branches,number of leaves and yield of Ginkgo biloba trees(4.5 a)showed an increasing trend.When the planting density was 2.0×104 trees/hm2,the growth rate of Ginkgo biloba trees was better and the yield was higher.
