对薄壳山核桃根插繁殖和播种繁殖2种育苗方法的改良技术进行田间实验研究。根插实验采用粗度分组的比较方法,提出了根插繁殖时适宜的粗度及其相应长度;播种实验采用改良露地播种的方法明显提高了播种当年苗木地上部的生长量。
A field experiment was conducted on the improved techniques of two kinds of seedling breeding methods for pecan root propagation and sowing and propagation. In the experiment of root insertion, the method of grouping by coarseness was adopted, and the suitable thickness and corresponding length of root explants were put forward. The sowing experiment improved the growth of seedling shoot by the method of improved open field.
