对于板栗树体营养状况的诊断来说,利用休眠期的枝条分析比翌年的叶分析在时机上更为有利,可以及时发现问题并采取相应措施。本试验通过对迸入休眠期板粟枝的分析测定,着重考察枝内营养浓度与枝龄的相关性,以探讨枝分析用于板粟营养诊断的可能性。
For the diagnosis of chestnut tree nutritional status, the use of dormant branches of the analysis than in the next year’s leaf analysis is more favorable in timing, the problems can be found in time and take appropriate measures. In this study, we investigated the correlation between nutrient concentration in branches and branch age through the analysis and determination of poplar in the dormant stage, in order to explore the possibility of branch analysis for nutrition diagnosis of poplar.
