氮添加施配有机肥对白皮松生长的影响

Effects of Nitrogen Addition and Organic Fertilizer on the Growth of Pinus bungeana

为确定有机肥施用量对白皮松生长情况的影响,于2020年—2022年进行了试验,设置了6个不同的施肥处理进行试验分析。结果显示:与未施用有机肥的CK处理相比,T1~T5处理的生长量和氮磷钾元素含量均显著增加(P<0.05),并且均在有机肥施用量为175 g/m^(2)时达到最高值,说明适量的有机肥能较大程度地影响白皮松的生长。

In order to determine the effect of the amount of organic fertilizer application on the growth of Pinus bungeana,experiments were conducted from 2020 to 2022.The results showed as follows:compared with CK treatment without organic fertilizer,the growth amount and nitrogen,phosphorus and potassium contents of T1~T5 treatment were significantly increased(P<0.05),and both reached the highest value when the organic fertilizer application amount was 175 g/m^(2),indicating that appropriate amount of organic fertilizer can greatly affect the growth of Pinus bungeana.
