摘 要:在闽楠播种苗生长期追施氯化钾复合肥、尿素+过磷酸钙、有机肥3种不同肥料以及采用兑水灌根、沟施、拌土撒施3种不同施肥方法进行了苗木生长效果比较试验。结果表明:选用氯化钾复合肥的追肥效果最好,平均苗高、平均地径、平均主根长度、≥5 cm长Ⅰ级侧根平均条数、平均合格苗率、平均合格苗产量分别达47.6 cm、0.46 cm、24.3 cm、10.1条、95.6%、3.82万株/666.7 m^(2);追肥方法采用兑水灌根的效果最好,上述6项苗木生长指标分别达48.3 cm、0.48 cm、24.7 cm、10.3条、97.0%、3.88万株/666.7m^(2)。In the growing stage of Phoebe bournei(Hemsl.)Yang sowing seedlings,three different fertilizers were applied with potassium chloride compound fertilizer,urea+calcium superphosphate and organic fertilizer,and the comparative experiment of seedling growth effect was carried out by three different fertilization methods of water irrigation,ditch application and mixing soil sprinkling.The results showed that the topdressing effect of potassium chloride compound fertilizer was the best.The average seedlings height,average diameter,average main root length,average number of≥5cm long-levelⅠside root,average qualified seedlings,and average qualified seedlings is 47.6cm,0.46cm,24.3cm,10.1,95.6%,38,200 plants/666.7m2,respectively;The topdressing method has the best effect of irrigating roots with water,and the above six seedling growth indicators reach 48.3cm,0.48cm,24.7cm,10.3,97.0%,and 38,800 plants/666.7m^(2),respectively.
