摘　　要：对幼龄胶园间作大叶千斤拔模式下的保护带植物进行刈割还田处理,结果表明,不同类型的植物需采取不同的刈割策略,对灌木类植物,刈割留茬高度应在100 cm左右,刈割时高度应在160~200 cm,即旱季11月至次年5月刈割1~2次,雨季6-10月刈割2~3次;对草本类植物,刈割留茬高度应在15 cm左右,刈割时高度应在50~60 cm,即旱季刈割2次左右,雨季刈割3~4次。In this paper,experiment blocks have been designed to determine the plant biomass,survival rate,soil content,temperature and nutrition of Flemingia macrophylla intercropping in young rubber plantation when return it to field after mowing.The results have showed that mowing management should be treated in accordance with the types of plants in the protection belts.The optimum stubble height and mowing height are around 100 cm and 160 to 200 cm for shrub plant.Namely,start mowing plant once or twice from November to May of next year in dry season,twice or three times from June to October in wet season.As to herbaceous plants,the stubble height and mowing height should be kept in 15 cm or so and 50 to 60 cm,respectively.That is to say,start mowing about twice in dry season and three or four times in wet season.
