Discussion on the Specifications of Salix Matsudana Koidz Cuttings and Their Seedling Cultivation Techniques
Salix matsudana Koidz is a deciduous tree in the Salix family and genus,with a height of about 20m and a diameter at breast height of over 1m.Distributed along rivers,lakes,roads,ditches,and villages in Sichuan,shallow mountains,and Naoshan of our province,it has the characteristics of fast growth,strong adaptability,and wide use.It is an important local tree species in our province,playing an important role in improving the ecological environment and maintaining soil and water.The afforestation and greening of Salix mandshurica are directly influenced by seedling cultivation technology.Therefore,this paper focuses on exploring the cutting specifications and seedling cultivation techniques of Salix matsudana Koidz by setting up 37 standard plots in conjunction with nursery production.By investigating the effects of cutting age,location,length,and coarseness on the growth of 16 standard plots from No.1 to No.16,the optimal cutting specifications were determined;Through an experimental investigation on the effects of cutting time,method,depth,density,and watering frequency on the growth of 21 standard plots from No.17 to No.37,the most suitable cutting seedling cultivation technology for Salix matsudana Koidz was determined,in order to provide technical guidance for the production of Salix matsudana Koidz seedlings in our province.
