山东省五莲县李树栽培历史悠久，但由于长期管理粗放。生产上普遍存在着结果晚、产量低、质量差的问题，全县４８万株李树年产量仅９０万ｋｇ左右，平均株产为１．８８ｋｇ。为探讨丘陵地李树早期丰产优质栽培技术，尽快获得经济效益，我们进行了此项试验。１　试验园基本情况 Wulian County, Shandong Province Li tree cultivation has a long history, but due to extensive management of long-term. Production is widespread with the consequences of late, low yield, poor quality issues, the county 480,000 Li tree annual output of only 900,000 kg or so, the average plant yield of 1.88kg. In order to explore early hilly Li Shu high yield cultivation techniques, as soon as possible to obtain economic benefits, we conducted this experiment. 1 test garden basic situation
