一、引言啤酒花有一多年生的根茎,但每年其气生的生长部分均凋谢于地面,依传统惯例每年夏季栽培时均培土将根部埋入土下,这样啤酒花的茎就会埋得越来越深了。冬季切断时,这些变得粗厚起来的酒花茎叫做“带状插条”(strapcuts)。这是新的酒花种植园或者原来的种植园中补栽缺株时用的种植材料的平常的来源。在植株死去后,冬季取下这些插条时往往无从检查取下的是否是健康无病的甚至无法核对是否是所需要的那种栽培 I. INTRODUCTION Hops have a perennial rhizome, but its annual growth of aerial parts are withered on the ground, according to the traditional practice of summer cultivation every year when the soil will be buried under the soil, so hops will be buried deeper and deeper . These strands of harvested hops are called “strapcuts” when winter is cut off. This is the usual source of plantation material for new hops or original plantations. After the plants have died, it is often impossible to check whether the removal of the cuttings in winter is healthy or disease-free and can not even check whether the cuttings are needed
