在宁夏灵武白芨滩国家级自然保护区,采用正交试验设计,针对影响梭梭苗木产量和质量的5个主要因素———播种时间、播种方法、施肥量、覆土厚度和播种量进行了系统研究,观测了4种处理条件下梭梭的出苗率、苗高、合格苗产量,然后运用方差分析和极差分析的方法分析了影响梭梭苗木质量和产量的因素,总结了一套适合在宁夏沙地进行梭梭育苗的技术.
In Lingwu Baibantan National Nature Reserve in Ningxia, orthogonal experimental design was adopted. According to the five main factors influencing the yield and quality of Haloxylon ammodendron seedlings, such as sowing time, sowing method, fertilizer application, covering thickness and seeding rate The seedling height, seedling height and qualified seedling yield of Haloxylon ammodendron under four treatment conditions were systematically studied. The factors affecting the seedling quality and yield of Haloxylon ammodendron were analyzed by means of analysis of variance and range of difference. A set of suitable factors Seedling cultivation in sandy land of Ningxia.
