密度和施肥对楠木播种苗生长的影响

应用随机区组设计在田间全光条件下进行楠木不同播种育苗密度和苗期追施不同肥料种类的比较研究,结果表明:播种密度和不同肥料处理对楠木1年生播种苗的生长量和苗木质量具有极显著影响,以株行距10 cm×10 cm的播种密度结合苗期追施速效复合肥或生物有机肥的平均生长量最大、单位面积的合格苗产量最高。

Effects of Density and Fertilization on Phoebe bournei Seedling Growth

Using random block design in the field under all light conditions,Comparative Tests of Phoebe bournei seedling density and applying different topdressing kinds in the seedling period were conducted,the results showed that:planting density and fertilization treatments had an significant impact on 1 year old Phoebe bournei seedling growth and seedling quality,under planting density of row spacing of 10cm × 10cm seedlings,seedling period,and available compound fertilizer or organic fertilizer,the average growth was the largest,yield of qualified seedlings was the highest per unit area.
