摘要
对不同栽植模式的3~6a生叶用银杏园产量进行调查,结果表明:在叶用银杏园3~6a的幼龄阶段,栽植模式对叶产量影响很大,单株叶产量受株行距影响较大,单位面积产量受栽植密度影响更大,相同密度不同栽植方式在一定程度上也影响叶产量,株行距为30cm×40cm/80cm的栽植模式较好。
The leaf yield of ginkgo in 3 to 6 years old with different planting mode were studied.The results were as follows:The planting mode had a great influence on the leaf yield in 3 to 6-year-old leaf-producing ginkgo.Plant spacing had a greater effect on the leaf yield per plant,as the planting density had a larger in原fluence on leaf yield per unit area.The leaf yield were influenced of the same density but different planting mode to some degree.Plant spacing with 30cm*40cm/80cm was better to higher leaf yield.
