朱砂根不同播种育苗方式效果分析

通过种子不同处理方法、选用不同土壤基质、贮藏方法、苗床覆盖、遮荫处理以及不同育苗密度进行试验对比,采用有序样本聚类分析法将朱砂根1年生播种苗的高生长过程划分为出苗期、生长初期、速生期、苗木硬化期4个时期,并进行苗木的生物量测定。结果表明：朱砂根播种育苗以种子去果皮、混沙湿藏,营养土（袋）播种,播后床面用地膜小拱棚＋谷皮覆盖处理的发芽率最高;以75%的拱棚遮荫朱砂根的生长量最大,以株行距8 cm×8 cm（150株/m2）的密度合格苗产量最高,成本最低;田间苗床播种育苗比营养袋播种育苗的生长量及生物量大,但朱砂根为常绿植物,建议在生产上推广营养袋育苗,以提高移栽成活率。

Effect Analysis of Different Way of Planting Seedlings of Ardisia crenata

Through different methods of curing seeds,different soil matrix,storage methods,bed covering,shading and seedling density were selected to make contrast test.The high-growth process of one-year-old seedlings of Ardisia crenata was divided into four periods of seedling period,early growth,fast-growing period and seedlings hardening period using orderly samples cluster analysis,and seedling biomass was determined.The results show that the germination rate of Ardisia crenata seedling that taking the curing tha...
