摘要
采用容器(10 cm×10 cm营养钵)和田间苗床2种播种育苗方式,进行了竹柏不同播种密度、不同遮荫处理的比较试验,结果表明:2种育苗方式对竹柏种子的发芽率没有显著影响,田间苗床播种苗的生长量大于容器苗;田间苗床的播种密度以株行距10 cm×20 cm最为适宜,生长量最大;生长期遮荫对竹柏播种苗有极显著影响,遮荫处理的苗木保存率达92.3%,未遮荫的苗木保存率只有37.5%。
Taking the container（10×10 cm nutrition bowl） and field seedbed 2 planting nursery ways,the compare Podocarpus nagi test of different seeding density and different shading treatments was conducted,the results showed that：2 kinds of breeding methods had not significantly impact on the Podocarpus nagi seed germination,the field seedbed seedling growth amount was larger than container seedling height;field seedbed planting density was the most appropriate（spacing of 10 cm×20 cm）for maximum growth;shading for Podocarpus nagi seedlings had significant effects in the growing season,the handling seedlings saved rate reached 92.3% with shading and the seedlings preservation rate reached 37.5% without shading.
