Abstract
[Objective] This paper was in order to improve walnut quality,standardize nursery stock market and establish a rational grade scale of the walnut seedlings quality.[Method]The data of 10 nurseries at Jiyuan City of Henan Province and other places was analyzed by the small sample random sampling and SAS software.Some traits such as the seedling height,ground diameter and so on were investigated in order to choose the seedling quality grading index.[Result]Seedling height,stem diameter and ground diameter can be used as the major indexes in the walnut seedling quality grading.The quality classification standard was as follows:Annual,Class I grafted seedling(seedling height 60 cm,stem diameter 0.8 cm);Annual,Class Ⅱ grafted seedling(seedling height 40 cm,stem diameter 0.6 cm);Biennial,Class I grafted seedling(seedling height 80 cm,stem diameter 1.0 cm);Biennial,Class Ⅱ grafted seedling(seedling height 60 cm,stem diameter 0.8 cm).[Conclusion]Combined with the national standard and expert advice,grade scale of grafted walnut seedlings quality was put forward from Comprehensive control conditions,seedling height,stem diameter,ground diameter and root system,etc.
