通过对香椿林分进行调查,井进行不同抚育方式、施肥和造林密度试验.结果表明,实行椿油(菜)间种是香椿幼林抚育的最佳方式;合理施肥显著促进林木生长,并以单施尿素4.5km/100m2或过磷酸钙7.5kg/100m2,15kg/100m2和22.5kg/100m2.以及混施尿素3kg/100m2加过磷酸钙15kg/100m2增多效果更为显著;若以培育香椿中小径级用材为目标,造林密度以1667~2615株/hm2为宜.并根据这些结果,提出了香椿优化栽培技术组合.
Through the investigation of the Toona sinensis stands, we conducted different tending methods, fertilization and afforestation density tests. The results showed that the best way was to cultivate the young forest of Toona sinensis with the intercropping of Chinese cabbage seed oil. The rational fertilization significantly promoted the growth of the forest. With single urea application 4.5km / 100m2 or superphosphate 7.5kg / 100m2, 15kg / 100m2 and 22.5kg / 100m2. And mixed urea 3kg / 100m2 plus calcium phosphate 15kg / 100m2 increased more significant effect; if to cultivate Toon small diameter timber as the goal, planting density to 1667 ~ 2615 plants / hm2 is appropriate. And based on these results, put forward a combination of Toon optimal cultivation techniques.
