摘要
该文对梧州市马尾松采脂林下种植的0.33hm21年生田七进行了取样分析,结果表明,1年生田七5个样地的生长量指标(株高、叶柄长、茎长、茎粗、根长、根粗、株鲜重、叶鲜重、根鲜重)、干样指标(叶干重、茎干重和根干重)相互间差异皆不显著。另外,叶、茎、根干鲜重比值分别达到66.7%、13.3%和35.5%;复叶数、复叶长、复叶宽、小叶数和叶面积这些与光照相关的指标,不同样地间差异不显著。可知,松林下辅以遮阳网的田七栽培模式能够满足田七对环境的需求。目前,林下1年生田七保存率为80.8%,单株平均根干重为2.7g,每公顷田七产量已达850.5kg,收益可达39.0882万元。可见,在梧州地区松林下种植田七模式具有较大的推广应用价值。
The experiment pine plantation of Wuzhou. was studied for 1-year-old The results showed that Tianqi of O. 33 hectare forests on tapped masson growth indicators （plant height, petiole length, stem length, stem diameter, root length, root diameter, plant fresh weight, leaf fresh weight, root fresh weight） and indicators （ the leaf dry weight, the stem dry weight and the root dry weight） were not significant among 5 plots. In addition, the ratio of dry/fresh for leaves, stems and roots were 66.7%, 13.3% and 35.5% respectively; the light-related indicators for numbers, lengths and widths of compound leaves, little leaf numbers and leaf areas had not significantly differences. So, it can meet Tianqi environmental needs with the cultivation mode of the shade net on mason pine for- ests. At present, the retention rate was 80. 8%, and the gain was up to 390 882 thousand RMB that the root dry weight of plant was 2. 7g and the production reached 850. 5kg per hectare. So, it had a better application value for the planting mode for pine forests in Wuzhou area.
