摘要
本文对建瓯杉木——山苍子三种不同套种模式的土壤结构、空隙、水分和短期收益及杉木生长进行研究。杉木——山苍子模式不仅能增加短期收益,而且套种后土壤物理性能得到改善,杉木幼林生长较快,是一种良好的山地套种模式,杉木——山苍子——烟叶、杉木——山苍子——黄豆模式短期收益虽好,但对土壤良好结构形成不利,因此应适当控制耕作强度,以免造成良好土壤物理性质的丧失。
Three patterns related to interplanting Litsea cubeba with Chinese fir in Jianou County were presented for the studies of the structure of the soil, the porousness of the soil, the moisture of the soil, the forest growing and the short time profit. The results show that the pattern not only incrcased a profit but improved the physical properties of the soil after the interplanting. Although the pattern of Chinese fir-Litsea cubeba-tobacco leaf and the pattern of Chinese fir-Litsea cubeba-soybean can profit better during a short time, they are unfavourable for the formation of a splendid structure of the soil due to the intensity of the cultivation.
