摘要

[目的]探索黑果枸杞硬枝扦插育苗对土壤环境的选择性，为优质苗木的工厂化生产提供技术参考。[方法]以甘肃省永靖县黑果枸杞一年生枝条为材料，对4种土壤基质中不同生根粉（BBT）和萘乙酸（NAA）处理浓度下黑果枸杞硬枝扦插后的成活率、生长状况、生根率及根系性状进行了测定和评价。[结果]①泥炭土、壤土、沙土均可用作黑果枸杞硬枝扦插基质，各浓度BBT和NAA处理下的成活率均分别在95%和80%以上；沙盐土不宜用于黑果枸杞扦插育苗； ②扦插后第10周，生根率最高的是泥炭土，其次是壤土，沙土最低，但沙土中已形成的根系在后期表现出快速生长的特点。③新生枝条长度在扦插后的前5周增长缓慢，之后显著增加；随育苗时间增长，植株间枝条生长量出现明显差异。[结论]从透气性和根系发育来看，泥炭土硬枝扦插的效果最好。从保水性来看，普通壤土和沙土均较好，但沙土生根率低，不建议使用。

Abstract

[Objective] The purposes of this experiment was to clarify soil suitability for Lycium ruthenicum hardwood cutting and to provide technical reference for industrialized production of high quality seeding.[Methods] The annual branches of Lycium ruthenicum were collected in Yongjing County of Gansu Province as experiment materials. These materials were treated by rooting powder(BBT) and naphthylacetic acid(NAA) in different concentration

and then were planted in four kinds of soil matrixs. The survival rates

growth conditions

rooting rates and root system characters were measured and evaluated.[Results] ① Peat soil

loamy soil

sandy soil all could be used for Lycium ruthenicum hardwood cutting. The survival rates of BBT treatment and NAA treatment in different concentration were above 95% and 80% respectively. Sandy saline soil was not suitable for Lycium ruthenicum hardwood cutting. ② Ten weeks later after plantation

new root proliferation was the highest for peat soil

the second was for loam soil and the least was for sandy soil. In sandy soil

the newly proliferated root was observed having rapid growth rate. ③ Length of new shoots increased slowly in the first 5 weeks and then grew quickly. Afterwards

branch growth got obvious equality in size.[Conclusion] In terms of air permeability and root development

the Lycium ruthenicum hardwood cutting in peat soil performed the best. From the perspective of water-retaining property

the normal loam and sandy soil both can provide good conditions for Lycium ruthenicum hardwood cutting

but the sand soil was not suggested to be used for Lycium ruthenicum hardwood cutting due to its low rooting rate.
