摘　　要：本试验就叶面肥料对枣树生长发育前期的影响进行了研究,结果表明:叶面施肥可增加枣树叶片厚度、叶面积、百叶重、花序数、枣吊长度及叶片数等。各种叶面肥的效果不尽相同,其中,"植物氨基酸液肥"的效果最好,"植物营养活力液"次之;矿质肥也有一定的效果。本文就枣树年周期中发育前期的发育特点及适宜的叶面肥料进行了讨论,并总结了叶面肥对不同指标的影响顺序。Effects of different foliage fertilizer on early growth and development of jujube trees were studied in the paper. The results showed that foliage dressing increased leaf thickness, leaf area, leaf weight, number of inflorescence, bearing branch length and number of leaves,etc.The results differed with fertilizers. Fertilizer ＂the Amino Acid Liquid Fertilizer of Plant＂ showed the best effects on jujube tree development, followed by the amino acid fertilizers and mineral fertilizers.And, the developmental characteristics in the early stage in a year and the proper foliage fertilizers were also discussed in the paper. Also, the influencing sequence on the above indexes of foliage fertilizers was summarized.
