不同施肥处理对设施栽培香椿产量的影响

在设施大棚内以云南省宜良县3年生香椿为材料，采用正交试验设计，就不同施肥处理对香椿产量的影响情况进行了试验研究和数据分析。结果表明，不同施肥处理对香椿产量有显著影响，其中对香椿产量影响最大的因素是叶面肥，其次是复合肥（液肥）施肥量，施肥间隔时间对香椿产量的影响不显著。对设施大棚内香椿嫩芽产量影响最大的施肥处理为：每10 d对其施用叶面肥（0.2%尿素）和复合肥（液肥）（45 g/m2）。该研究可为当地香椿设施栽培提供施肥依据。
Three year old seedlings of Toona sinensis cultivated in greenhouse were used as experimental materials in this study. The influences of different fertilization on production of T. sinensis was investigated by an orthogonal design. The results showed that different fertilization treatments significantly influenced on production of T. sinensis. Among the various fertilization treatments, the most significant factor affecting production of T. sinensis was foliar fertilizer, followed by the amount of compound fertilizer. The effect of fertilizer time was not significant. The optimal fertilizer treatment for production of T. sinensis was spraying foliar fertilizer (0.2% urea) and compound fertilizer (45 g/m2) every ten days.The research provides guidance for fertilization of T. sinensis cultivated in greenhouse
