老挝北部山区水稻—菜豆水旱轮作栽培模式

摘要

After several years of demonstration and pr omotion, a paddy-upland crop rotation pattern between paddy rice and kidney bean had been developed in the mountainous areas of north Laos, and gained great economic benefit. The yield of kidney bean was 1 200~1 400 kg/hm2, with an output value of 5 000~7 000 RMB.The rotation cropping increased the farmer's income by 1 500 to 2 500 RMB,and made great contribution to Laos'economic and social development.%通过多年的示范推广,老挝北部山区已形成了水稻—菜豆水旱轮作栽培模式,产生了较好的经济效益.667 m2菜豆产量1200~1400 kg,产值5000~7000元,为农民增加经济收入1500~2500元,为当地的经济社会发展做出重要贡献.
