摘要
对浙南山地桃园套种白三叶、紫花苜蓿、黑麦草、百喜草与适度留草和清耕进行了研究,结果表明,四种牧草均具有一定的适应性,对改良果园环境、提高土壤肥力和增加经济效益均有一定作用。其中,白三叶草在浙南山区桃园内生长繁殖快,产量可达39000kg/hm2,在4种牧草中其温度调节作用、水土保持效果、培肥土壤能力和桃园的经济效益最好,值得推广应用。
Four kinds of forages（Trifolium repens , Medieago sativa, Lolium perenne, Paspalum notatum） intereropped with mountainous peach orchard were studied in south of Zhejiang province, compared with moderate keeping natural grass and clean tillage. The result indicated that four forages verities have obvious effect on environment, soil fertility, and economic benefits of orchard. Among four forages, the T.repens grow better and faster, the yield is 39 000 kg/hm2, which has best effect on thermoregulation, water and soil conservation, soil fertility improvement and economic benefits of peach orchard and suit for application in orchard of south of Zhejiang province.
