摘要

通过田间原位试验，研究橡胶凋落叶覆盖对平地和坡地胶园表层土壤理化性质的影响。试验设置平地凋落叶覆盖、平地凋落叶去除、坡地凋落叶覆盖和坡地凋落叶去除4个处理。结果表明：（1）平地胶园表层土壤含水率大于坡地，凋落叶覆盖较凋落叶去除的坡地土壤含水率显著增加；（2）表层土壤含水率与降雨量呈线性正相关关系，方程斜率表现为坡地大于平地；（3）平地和坡地凋落叶覆盖较其凋落叶去除的土壤pH分别提高了0.09~0.74和-0.09~0.47个单位；（4）与凋落叶去除相比，凋落叶覆盖的有机碳、全氮和碳氮比均有所增加，平地增幅分别为6.9%~68.5%，3.0%~44.8%，3.9%~16.2%，坡地增幅分别为23.3%~95.0%，3.5%~52.5%，7.6%~27.9%，坡地增幅大于平地；（5）与凋落叶去除相比，凋落叶覆盖显著提高平地土壤有效磷含量，增幅为6.2%~48.1%，显著提高平地和坡地速效钾含量，增幅分别为16.4%~83.3%和12.8%~94.8%。综上所述，橡胶凋落叶覆盖可以缓解胶园pH酸化，增加土壤保水能力，改善土壤养分状况。

Abstract

In order to reveal the effects of rubber litter covered on the surface soil physiochemical properties in different slop gradient

a field experiment was conducted. The four experimental treatments included leaf litter covered and litter removed in flat land

leaf litter covered and litter removed in slope land

respectively. The results showed that:(1) The soil water contents in flat land were higher than that in slope land during litter decomposition

moreover

it increased significantly at the treatments of litter covered compared with the treatments of litter removed in the condition of slope land. (2) There was a linear positive correlation between surface soil water content and precipitation

while the equation slop of slope land was larger than the flat land condition. (3) Treatments of litter covered in flat land and slope land increased the pH values by 0.09~0.74 and -0.09~0.47 units

respectively. (4) Total organic carbon

total nitrogen and C/N of treatments of litter covered increased significantly by 6.9%~68.5%

3.0%~44.8%

3.9%~16.2% respectively in flat land and 23.3%~95.0%

3.5%~52.5%

7.6%~27.9% respectively in slope land

compared with these of litter removed

while the increase rate in slope land was greater than that in flat land. (5) Compared with the treatments of litter removed

the treatments of litter covered increased significantly soil available phosphorus contents in slope land condition by 6.2%~48.1%

however

increased significantly soil available potassium contents in flat land by 16.4%~83.3% and in slope land by 12.8%~94.8%. In conclusion

rubber leaf litter covered could alleviate soil acidification

increase the water retention capacity and improve the conditions of soil nutrients.
