摘要：经 13a的马尾松幼林施肥试验表明 ,红壤地区施P肥有利于马尾松幼林生长 ,但产生肥效迟(施肥 7a后产生显著效果 ) ,施N、K肥对促进马尾松幼林生长无显著影响 ,过量还会产生负效应。施N、K肥会促进林木分化 ,施P肥则能使林分结构均一 ,经偏相关分析表明 ,P元素是影响马尾松生长的主要因子 ,肥效有一定的时效性和增益持续性。施肥最佳处理组合为N1P3K2 ,即每公顷施N、P、K分别为 0、30、30kg。
Thirteen years’ test of Pinus massoniana plantation fertilization showed that fertilizing P on red soil area benefited the growth of P. massoniana young plantation, but the effect of fertilizer began appear in the seventh years after fertilizing. N and K had no significant effect on the growth of P. massoniana young plantation and negative effect would appear if overdose fertilizers were applied. N and K would promote the differentiation of forest trees while P could make the stand structure unified. The result of partial correlation analysis showed that P was the key factor affecting the growth of P. massoniana . The effectiveness of fertilizer could last for certain a period and had gain sustainability. The best combination of fertilizer was N 1P 3K 2, i.e. the applying ratio of N, P and K fertilizers should be 0 kg∶30 kg∶30 kg per hectare.
