山地幼龄果园一般立地条件差,土层薄,肥力低,地下岩位高,同时深耕松土、扩穴困难。既限制了根系的发展.又影响了树体的生长发育。为此,我们进行了山地果园低强度爆破松土试验,以探讨在山地条件下的深耕、扩穴的新方法。 试验自 1980年 12月至 1983年 10月在泰安市下港公社4年生
Young orchards in mountain areas generally poor site conditions, thin soil, low fertility, high underground rock, while deep plowing loose soil, expanding the hole difficult. It not only restricted the development of the root system but also affected the growth and development of the tree. To this end, we conducted a low-intensity blasting test on mountain orchards to explore new ways of deep plowing and hole-expanding under mountainous conditions. Test from December 1980 to October 1983 in Tai’an City, Hong Kong commune four years
