摘要
在相同的整地、种子处理、播种方式、苗期管理与病虫害防治措施的情况下,研究不同覆盖基质及播种时间对白皮松出苗及苗木生长的影响。结果表明:1)白皮松播种育苗选用腐殖质土作为覆盖基质出苗率最高,达93%;感病率最低,仅为6.5%;高生长量最大,达5.6 cm。2)在吕梁山南端白皮松播种时间为5月5日前后较为适宜,出苗整齐,出苗率高。
Under the same soil method, seed treatment, sowing method, seedling management and pest control measure, the effect of mulch and sowing time on seedling's emergence of Pinus bungeana was studied. The results showed that, 1) Taking humus soil as covering had the highest emergence rate (93 % ); The diseased seedling rate was the lowest (6.5%); Height increment was the biggest (5.6 cm). 2) Sowing time of Pinus bungeana in the south of Luliang Mountain was before or after May 5 th, then emergence was regular and emergence rate was higher.
