摘要
对杉木新造林地套种仙人草复合经营模式进行调查表明,杉木新造林地套种仙人草不仅能保护新造林地土壤,而且显著促进幼林生长,套种仙人草的杉木幼树平均树高、胸径为4.62 m和6.26 cm,分别比未套种林分高27.6%和48.3%。套种模式的短期收益显著,投入产出比在1∶6以上,达到了复合经营目的。本文还总结了杉木新造林地套种仙人草的关键技术。
The compound model of interplanting Mesora chinensis was investigated in new plantation of Chinese fir.The results show that the compound model not only protected the new planting foresty soil,but also significantly accelerated the growth of young forest,the mean height and mean diameter at breast height of saplings of Chinese fir were 4.62 m and 6.26 cm,which were 27.6% and 48.3% higher than CK respectively.The economic benfits of the interplanting model were significant,the input-output ratio was over 1∶ 6,and reached the compound management purpose.The key cultivation technigues of M.chinensis are summarized in terms of planting density,reproduction way,tending fertilization and harvesting date,et al.
