| 摘 要： | 试验主要针对园林中应用的针叶树种红皮云杉进行DRIS法营养诊断,以确定最佳采叶时期。结果表明:红皮云杉1 a内N、P、K矿质元素的含量在10月5日左右较为稳定,即养分含量变化较小,N、P、K的含量较接近全年的平均水平,此期为进行营养诊断的最佳采叶时期。

| Abstract: | By analyzing the contents of N,P,K mineral elements in samples in order to determine the best periods of leaf collection in nutritional diagnosis about Picea koraiensis Nakai by application DRIS.The results showed that on the day of October 5,N,P,K contents of mineral elements had a relatively stable period and the N,P,K contents were closer to the annual average level.Therefore,this was the best periods of leaf collection time by using the application DRIS method for nutritional diagnosis of Picea koraiens... |
