摘　　要：为满足迅速发展的有机果品生产中叶面喷肥的需要,本试验以梨花、槐花、梨幼果、藜嫩芽、芹菜叶为原料,经天然发酵制得植物源营养液叶面肥,分析了营养成分,并在梨品种‘雪青梨’树上做喷施试验。结果表明:梨花营养液的处理效果最为显著,新梢生长量比对照提高19.50%,叶面积比对照提高13.02%,单果重比对照提高38.65%,可溶性固形物比对照提高13.52%;在梨花营养液稀释500、300和100倍试验中,稀释500倍处理的效果最好,且显著优于南国春氨基酸叶面肥。Plant-derived leaf fertilizers were made from pear bloom, flowers of silver chain, young pears, sprouts of goosefoot, and leaves of celery by fermentation and the nutrition elements were analyzed. The effects of the five nutrient solutions on ‘Xueqing＇ pear were also analyzed. The results showed that the nutrient solution made from pear blooms was better than others and it increased the shoot length by 19.5%, soluble solid content by 13.52%, average weight per fruit by 38.65%, and leaf area by 13.02%. Among the 500-, 300-, 100-time dilution of the nutrient solution made from pear bloom, the 500 - time dilution showed the best performance, being much better than the amino acid leaf fertilizers, ‘ Nan Guochun＇.
