Cultivation and Management Technology of Chamaenerion conspersum and Its Application in Gardens

本文旨在更好地开发利用西藏丰富的柳兰属野生观赏植物资源,介绍网脉柳兰栽培管理技术及在园林中的应用,包括网脉柳兰的生物学特点;生长习性喜光而耐瘠薄适应性广;9至11月份采种,林芝地区3月末4月初温室低床播种,3~5d开始萌动伸出胚根,一星期后长出子叶,半月后开始长出第一片真叶;分株时间一般在休眠季,越冬根出条处于隐芽时进行;压条时间在6月份,此时网脉柳兰处于旺盛生长期,又逢雨季空气湿度大,易于生根;移植时间宜在实生幼苗高5cm左右时(从播种后算,60~75d),可分苗移栽,无性繁殖苗生根即可移植;施肥―前促后控‖,浇水见干见湿,中耕除草及时彻底;在园林中可应用于花境、花坛、点缀草坪或空旷处地被、边坡生态工程。运用乡土植物为西藏城镇园林绿化建设做出贡献。

In order to develop and utilize the wild ornamental plant resources of Chamaenerion in Tibet, because of it＇s light sensitive and barren tolerant. The paper introduces the cultivation and management technology and its application in gardens of C. conspersum. Including：（1） In seed propagation, seeds collected from September to November, Planting in low bed in greenhouse in late March and early April in Nyingchi, It began to germinate and protrude radicle in 5 days, cotyledon after one week, and the first true leaf after half a month later, The time of transplantation should be about 5 cm higher than that of real seedling（from after sowing, 60 to 75 D）.（2）The point time of division propagation is usually in dormant season when root sucker have kryptoblast.（3）The layering time is in June, as this time is in the rainy season, C. conspersum is in the vigorous growing period, and the air humidity is high, so it is easy to take root.（4）both seedlings and clones can be transplanted under open garden comply with appling fertilizer ＂Prophase promotion, Later stage control＂, pouring water ―after dry then irrigating＂, timely and thorough weeding, C. conspersum can be used in garden as bed flower, cutting flower, Soil and water conservation plant after 1 year.
