摘要
幼龄红松果林栽培密度低,无经济效益。近几年来,利用作物生长时间、空间差,在幼龄红松果林套作紫花苜蓿,取得了明显的生态、经济效益。从林地选择、品种选择、红松果林营建、套种方式、紫花苜蓿播种、水肥管理、主要病虫害防治、红松幼树管理、紫花苜蓿收割和利用等方面介绍该套作栽培技术。
Due to the low planting density of young Korean pine fruit forest,there is no economic benefit.In recent years,due to the poor growth time and space of crops,we have made obvious ecological and economic benefits by intercropping alfalfa reasonably in the field of young Korean pine trees.In this paper,the cultivation techniques of the interplanting model were summarized from the aspects of woodland selection,breed selection,construction of Korean pine fruit forest,interplanting mode,alfalfa sowing,water and fertilizer management,pest control,management of young Korean pine trees,alfalfa cutting and storage.
