人工栽培状态下3种野菜的生长动态

Growth Danamics of Three Kinds of Wild Vegetables under Artificial Cultivation

对菊花脑、人参菜、益母草3种野菜在人工栽培条件下的生长规律进行了研究。结果表明,菊花脑适合于密植,以10 cm×15 cm为宜;株行距加大,植株叶片数、分枝数反面变少,单株叶面积也变小。人参菜生长速度较快,生长期长,表现为营养生长与生殖生长并行。益母草株行距增大,株型变高,单株叶片数增多,单株叶面积加大,以20 cm×25 cm作为人工栽培株行距为宜。

Under artificial cultivation, the growth danamics of three kinds of wild vegetables including Chrysanthemum nankingense Hand. Mazz. , Talinum paniculatum （Jacq.）Gaertn and Leonurus heterophyllus Sweet were studied. The results indicated that： close planting was suitable and 10 cm× 15 cm was optimical plant- row spacing for Chrysanthemum nankingense Hand. Mazz. ;on the contrary , the enlarged plant--row spacing made leaves number per plant fewer , branches number per plant fewer and leaves areas per plant smaller. But for Talinum paniculatum（Jacq. ）Gaertn ,the growth speed was quicker and the growth period was longer, showing that nutrition growth and reproduction growth went side by side. With the enlarged plant-row spacing of Leonurus heterophyllus Sweet, plants became more taller, branches number per plant became more and leaves areas per plant became smaller, 20 cm×25 cm was an artificial cultivation plant-row spacing for Leonurus heterophyllus Sweet.
