摘要
试验研究了喷施不同类型叶面肥对忍冬生长指标的影响。结果表明,氨基酸+全微量元素叶面肥和全微量元素叶面肥均能显著缩短花枝节间长度,从而提高单位长度花枝上的花蕾数量,有助于提高产量;喷施氮磷钾复合肥和氮肥对花枝节间长度有显著促进作用,能显著降低单位长度花枝上的花蕾数,进而造成减产。喷施磷钾动力叶面肥和铁肥叶面肥对忍冬花蕾伸长和(或)花蕾鲜重有显著促进作用;喷施全微量元素叶面肥、氨基酸+全微量元素叶面肥和激素DCPTA〔2-(3,4-二氯苯氧基)-乙基-二乙胺〕对忍冬叶片大小及鲜重有促进作用,有助于提高金银花产量。
The effects of different types of foliar fertilizers on growth indexes of Lonicera japonica were studied in this paper. The results showed that the foliar fertilizer with full microelement and the one with amino acid ＋ full microelement could decrease the internode length of flowering branch significantly, and then the number of flower buds would increase on per unit length of branch, which was benefit to improving yield. The nitrogen fertilizer and the compound fertilizer of nitrogen, phosphorus and potassium increased the intemode length of flowering branch significantly, so the number of flower buds decreased on per unit length of flowering branch, which resulted in the decrease of yield. It was also found that phosphorus -potassium foliar fertilizer and iron foliar fertilizer promoted the prolongation and （or） fresh weight of flower buds ; spraying hormone DCP- TA, full microelement foliar fertilizer, and amino acid on leaf area and fresh weight of Lonicera japonica ; all yield. ＋ full microelement foliar fertilizer had promotion effect the five foliar fertilizers would be helpful to the flower
