| 摘 要： | 以自然生草为对照,综合比较鲁梅克斯、三叶草、菊苣、紫花苜蓿、高羊茅、黑麦草几种牧草生草覆盖对梨园土壤理化性质及养分含量的影响,结果表明:与自然生草相比,几种生草处理表现为土壤温度、含水量、N及P含量降低,土壤容重、K含量升高。紫花苜蓿、黑麦草和自然生草覆盖有机质含量相当,是本地区果园生草管理较理想的选择,其它各处理显著低于自然生草处理。

| Abstract: | By using natural grass-sowing as control,experiments were carried out to investigate the effects of different sod-mulching including rumex,clover,chicory,alfalfa,tall fescue and ryegrass on physic-chemical characters and nutrients of pear orchard soil.The results showed that sod-mulching could reduce soil temperature,soil moisture content,and the contents of nitrogen and phosphorus;and increase soil bulk density and potassium content.Soil covered with alfalfa and ryegrass had similar organic matter contents with the control;the others had significantly lower contents.These results suggested that alfalfa,ryegrass and natural grass-sowing were good choices for orchard soil management. |
