摘要
通过营养袋栽培试验,研究了污泥营养基质对尾巨桉苗木生长的影响。结果表明,污泥营养基质能 够显著促进尾巨桉苗木的生长,显著增加尾巨桉苗木树冠、地径和总生物量,其中以80％赤红壤+20％污泥和 70％赤红壤+30％污泥2种营养基质的效果最好。污泥营养基质能够显著提高尾巨桉苗木叶片的叶绿素和N、P、K 含量,但对尾巨桉苗木叶片的Cu、Zn含量没有影响。
A plastic bag cultivation experiment was conducted to study the effect of sludge nutritional media on the growth of seedlings of Eucalyptus urophylla ×E. grandis. The results indicated that sludge nutritional growth media could significantly stimulate seedling growth in terms of larger canopy size ,larger stem diameter and biomass. The best treatments were 80% laterite soi1＋20% sludge and 70% laterite soil ＋30% sludge. The sludge growth media could markedly increase leaf chlorophyll ,leaf N ,P and K contents but showed no positive effects on leaf Cu and Zn contents.
