野生蔬菜地笋扦插繁殖规律的研究

对野生蔬菜地笋的不同材料、不同方式的扦插苗的生根规律、生长动态进行了初步研究.结果表明:地笋扦插苗的生根数量随着扦插时间的延长呈上升趋势,其中主茎扦插苗的生根数量多于侧茎,生根时间提早于侧茎.根据对扦插苗生长过程中的株高、茎粗、叶片数的变化的观察可将扦插苗的生长期划分为快速生长期、生长平缓期和生长稳定期.不同的扦插材料影响着植株的生长动态,主茎易成活且长势好,侧茎则明显不如主茎;扦插方式的不同,对植株生长动态也起作用,直立式扦插和全埋式扦插苗在生长期变化明显.

Rearch on the Root Growth Dynamics of Shoot Cuttings in Wild Vegetable Disun

Different materials,different ways of rooting cuttings law,growth dynamics of Poot growth of shoot cuttins in wild vegetables was studied study.The results showed:rooting cuttings volume was increased with the extension of shoot cutting time.which the main stem cuttings rooting side more than the number of stems,roots earlier in the side of the stem.According to the cuttings in the process of growth of plant height,stem diameter,number of leaves,the largest leaf area(the largest leaf length * width) of the observed changes may be cuttings grow into fast growing,slow growth period of stability and growth period.Cutting different materials affect plant growth dynamics,and the main stem easily survived vigor,stem side of the main stem was significantly better;Cutting the different methods of plant growth dynamics also play a role,vertical cutting and buried all the cuttings grow significantly change.
