| 摘 要： | 为了研究5-氨基乙酰丙酸对山地枣树生长发育和产量品质的影响,选用9 a生盛果期矮化密植梨枣树为材料,采用田间试验和实验室分析相结合的方法,研究了叶面喷施5-氨基乙酰丙酸对枣果纵径和横径、叶片相对叶绿素含量、品质和产量的影响。结果表明:叶面喷施稀释800倍的5-氨基乙酰丙酸对枣树的生长发育、产量和品质都有显著的促进作用。喷施后2次,枣果纵径比对照分别增加23.3%和27.1%,横径分别比对照增加17.2%和15.5%,采收期枣果纵径和横径分别比对照增加27.4%和23.1%,产量比对照增加24.6%,枣果品质明显高于对照。实际应用中采用稀释800倍的5-氨基乙酰丙酸喷施效果最佳。

| Abstract: | Effects of 5-aminolevulinic acid on the growth,yield and quality of compactly planted jujube in the mountainous region were studied.9-year-old pear jujube plants were selected as materials.Jujube longitudinal diameter,horizontal diameter,content of chlorophyll,fruit yield and fruit quality were measured.The results showed that the growth,fruit yields and quality were promoted by spraying 800 times dilutions of 5-aminolevulinic acid.Compared to the control,longitudinal diameter increased by 23.3% and 27.1% a... |
