摘要:
 为研究不同绿肥对桉树人工林土壤理化性质的改良效果,选取华安县西陂国有林场桉树人工林进行套种扁豆、乌绿豆×印度豇豆及不套种绿肥方式,对土壤理化性质的3 a动态影响研究。结果表明,套种绿肥对桉树人工林生态系统有积极影响,桉树人工林套种绿肥有改善土壤的物理化学性质的作用,综合改良效果表现为:套种乌绿豆×印度豇豆>套种扁豆>不套种。其中套种乌绿豆×印度豇豆下,3个土层土壤容重在造林3 a时对比造林0.5 a时增加了-0.79%~7.27%,而全N、全P含量分别下降了-18.60%~3.9%和-5.56%~8.70%,均明显低于不套种的9.76%~14.15%、2.52%~4.65%和4.76%~15%。而套种乌绿豆×印度豇豆方式下,土壤水解性N、有效P和速效K含量在造林1.5 a时比造林0.5 a时分别减少了2.65%~61.54%、12.50%~31.79%和25.06%~25.93%,对比不套种的47.83%~64.79%、18.56%~37.00%和29.98%~56.29%,说明套种乌绿豆×印度豇豆对土壤速效养分维持效果优,而且在一定程度上对土壤养分的积累产生积极作用。本研究还发现套种乌绿豆×印度豇豆能够提高土壤有机质含量,改善土壤pH值,缓解土壤酸化,所以该套种模式值得在生产上进一步推广应用。
Abstract:
 In order to study soil improvement effect of interplanting different green manures on the soil physical and chemical properties of eucalyptus plantation,Xiqiao National Forest Farm of Hua’an County was selected as experimental site to carry out a 3-year-long dynamic study.Three different cultivation modes were adopted: eucalyptus was interplanted with lentil (A),with green mung bean×Indian cowpea (B),without interplanting (C).Soil samples were collected 0.5,1.5 ,and 3 years after the commencement of the experiment from three soil layers: 0-20,20-40,and 40-60 cm.The results showed that interplanting green manures had positive impacts on the eucalyptus plantation ecosystem.The comprehensive improvement effects on soil physico-chemical properties of three cultivation modes were in the order of B>A>C.In mode B,the soil bulk density of the 3-year soil increased by -0.79% to 7.27% compared with that in 0.5 year soil,while the total nitrogen and total phosphorus contents decreased by -18.60% to 3.9% and from -5.56% to 8.70%,respectively,they were significantly lower than the corresponding values of non-interplanting soil: 9.76% to 14.15%,2.52% to 4.65%,and 4.76% to 15%.The contents of soil hydrolyzable nitrogen,available phosphorus and available potassium in the mode B reduced by 2.65%-61.54%,12.50%-31.79% and 25.06%-25.93%,respectively in the 1.5 year soil compared with those of 0.5 year soil,in the mode C,the corresponding figures were 47.83%-64.79%,18.56%-37.00% and 29.98%-56.29%,indicating that the mode B demonstrated excellent effect on soil available nutrient maintenance,and it had a positive effect on soil nutrient accumulation to some extents.The experiment also found that mode B could increase soil organic matter content,improve soil pH and alleviate soil acidification,so this cultivation was worthy of further application in production.
