摘要
种植在农地上的旱冬瓜能促进农作物生长,据测定1t旱冬瓜树叶干物质量的肥力相当于14.3kg硫酸铵、2.4kg过磷酸钙和2.2kg硫酸钾,农户习惯以鲜叶6000～7500kg/hm^2替代1.5万kg/hm^2水稻种植的有机圈肥,并分析了喜玛拉雅地区印度东北部和中国云南省以旱冬瓜为基础的混农林轮作丢荒管理系统。
Alnus nepulesis intercropping with crops can improve the growth of crops.Traditionally,farmers are used to applying 6000-7500kg fresh leaf of Alnus sp.per hectare as the substitute of livestock fertilizer within the rice plantation because the fertility of 1000kg dry leaves of Alnus sp.equal to 14.3kg nitrogenous fertilizer,2.4kg phosphorus and 2.2kg kalium respectively.This article has described and analyzed the Alnus nepalesis-based mountainous intercropping and fallow system in Himalayan region from the eases of Northeast Indian and Yunnan Province of China.
