摘　　要：在半干旱区坡耕地,以兰州百合为试验材料,研究了4种新型叶面肥在兰州百合田现蕾前期、现蕾期、开花期喷施对百合生理指标及产量结果的影响。试验结果表明,在兰州百合生长期,叶面喷施高钾营养素、FA旱地龙、花多多、磷酸二氢钾对其株高、茎粗、叶片数、叶色、枯萎期和产量的提高都有比较显著的效果。说明4种叶面肥均可促进兰州百合生长发育,推迟枯萎期,从而显著提高单产,增加纯收益,均可在生产中推广应用。In semiarid hilly cropland area, the effects of physiological characteristics and yield of Lilium davidii var. unicolor were studied by spraying four kinds of new foliage fertilizers during early squaring period, squaring period and flowering period. The results showed that it could significantly increase plant height, stem diameter, the number of leaves, leaf color, wilting stage and bulb yield of L. davidii var. unicolor by foliar spraying high potassium nutrients, FA Handilong, Huaduoduo and potassium dihydrogen phosphate in growing season. It showed that the four kinds of fertilizer could promote the growth and development of Lily, delay wilting stage, significantly increase the lily yield and net income, thus it can promote in the production of L. davldii vat. unicolor.
