高海拔环境下栽培措施对藏产卷丹百合鳞茎生长特性的影响

Effects of different cultivation measures on the bulb growth characteristics of Lilium lancifolium Thunb.from Tibetan at high altitude

本研究旨在建立适合我区的卷丹百合(Lilium lancifolium Thunb.)种植技术体系。选用中等带茎苗和大田种植生长4年的藏产卷丹百合鳞茎为实验材料,探究不同栽培措施对卷丹百合鳞茎生长特性的影响情况。结果说明,我区藏产卷丹百合田间试验适宜的种植密度为株距25 cm,产业推广过程中建议种植密度可以调整为株距15 cm,待出苗齐整后铺设防草布,栽培第4年且选用抹除珠芽并打顶的田间管理方式,可以提高其产量,以期能够为藏产卷丹百合在我区推广应用奠定一定的研究基础。

This study aims to establish a suitable planting technology system for Lilium lancifolium in Tibet.Using medium stem seedlings and L.lancifolium bulbs grown in the field for 4 years as experimental materials,the effects of different cultivation measures on the growth characteristics of L.lancifolium bulbs were explored.The results indicate that the suitable planting density for the field experiment of L.lancifolium from Tibetan produced is 25 cm per plant.During the industrial promotion process,it is recommended to adjust the planting density to 15 cm per plant.After the emergence of seedlings is complete,protective grass cloth should be laid.In the fourth year of cultivation,the field management method of removing the pearl buds and topping can be used to increase its yield,laying a certain research foundation for the promotion and application of L.lancifolium produced in Tibet.
