施肥对诺丽寒害后恢复生长及产量的影响

The Effect of Fertilization on Recovery Growth and Yield of Morinda Citrifolia L.After Chilling Injury

试验选取寒害后修剪过的诺丽植株为材料,根部追施复合肥、普钙、草木灰,按不同配比设置9个处理,分析不同施肥水平对寒害后修剪过的诺丽植株株高、茎粗、冠幅和产量的影响。结果表明,施肥有利于寒害后植株的恢复和快速生长,互配施用比单一施复合肥的产量高,且植株长势好,单株施用量为"复合肥0.2 kg+普钙0.3 kg"的植株长势和产量最高,其次是施用"复合肥0.2 kg+草木灰0.3 kg"的植株。

Take pruned nori(Morinda Citrifolia L.)plant after chilling as material to investigate the effect of fertilizer level onplant height,stem diameter,crown width and yield,and nine levels of fertilizer treatments including compound fertilizer,calcium superphosphate,plant ash were chosen for root fertilization.The results showed that fertilization is beneficial to the recovery and rapid growth of the plant after chilling.The yield under interworking fertilizers treatment is higher than that of with single compound fertilizer only,and the plant grows well,too.The plant growth and yield would reach to the highest when application amount is 0.2 kg compound fertilizer and 0.3 kg general calcium for per tree,followed by the application of compound fertilizer 0.2 kg plus plant ash 0.3 kg.
