不同施肥量对厚荚相思人工林生长指标的影响
|
摘要
文章通过广西农业和林业上常用有机—无机复合肥对厚荚相思进行施肥的研究,为厚荚相思造林追肥提供合理的数据来源。试验结果表明:随着施肥量的增加,厚荚相思的平均树高和平均胸径生长先增加后趋于平衡,当施肥量达到1.25kg时,树高和胸径都增加最大,单株材积平均值也达到最大。
The research focused on the common use of organic-and-inorganic compound fertilizer in the fertilization of acacia crassicapa in agriculture and forestry in Guangxi, aiming to provide reasonable data sources for its afforestation and fertilization. Test results showed that with the increase of fertilization, the average height and DBH increased first, and then tend to balance.With the fertilizing amount of 1.25 kg, the height and diameter grew to the maximum and so did the average of the individual volume.
