根据叶分析指导施肥是先进国家果树生产中常用的方法之一。叶化学分析的可靠性和实用性,首先决定于取样技术。它包括取样时期、取叶数量、采叶部位、枝条种类、叶位等。不正确的取样必然导致叶分析得出错误的结论。对栗叶取样技术的研究,目前尚未见报道。为给栗树叶分析 According to leaf analysis, fertilization is one of the commonly used methods in the production of fruit trees in advanced countries. The reliability and practicality of chemical analysis of leaves depends primarily on the sampling technique. It includes the sampling period, take the number of leaves, leaf picking parts, branches of the type, leaf position and so on. Incorrect sampling inevitably leads to erroneous conclusions from leaf analysis. The chestnut leaf sampling technology, has not been reported. To analyze chestnut leaves
