摘要
通过几年山地和平地红松育苗试验,概括地总结了不同育苗地点、不同播种量、不同肥料种类对红松苗木的生长量及产量的影响,从试验结果看出,山地繁育红松苗比平地在生长量和苗木产量上都有较明显的提高,不同的肥料种类对红松苗的生长量有较大的差异,三元复合肥和腐熟鸡粪较单一化肥和不施肥的试验对照育苗效果较好。
Through years of seedling test for Pinus koraiensis Sieb. et Zucc. on mountains ＆ field, effect of different breeding sites, seeding rate, and fertilizers on growth ＆ yield of seedlings for P. koraiensis were summarized. Result shows that the growth and yield of Pinus koraiensis Sieb. et Zucc. increase significantly on mountains than that on field. Different types of fertilizers have significant differences effect on growth of Pinus koraiensis Sieb. et Zucc. ; the seedlings applicated with NPK fertilizer ＆ chicken manure grow well than that without fertilization.
