摘要
为减少德阳丘区鲜食枣裂果损失,通过田间药剂喷施和地膜覆盖对鲜食枣——金丝枣进行裂果防治试验。结果表明:植物生长调节剂中喷施20 mg.L-1a-萘乙酸与15 mg.L-1激动素混合液对金丝枣防裂效果最显著,裂果率为16.88%,较对照裂果(41.23%)降低24.35%。商品药剂中美钙镁对金丝枣防裂效果最显著,裂果率为16.98%,较对照裂果降低24.25%。而地膜处理与对照相比,防裂效果极显著,裂果率为16.39%,较对照裂果降低24.83%。
The experiment on preventing the cracking of fresh-eating golden silk jujubes has indicated that chemical spraying the field and plastic film covering can reduce the loss of dehiscent fruits in Deyang. Specifically, it is the most significant preventing cracking fruit effect to spray the liquid mixture of 20 mg·L^-1 a-NAA and 15 mg·L^-1 kinetin among plant growth regulators,and the cracking rate is 16. 88%, which decreases by 24. 35% as compared with the water control （41.23%）. Meanwhile, Meigaimei is the best commodity chemical in reducing the cracking rate （ 16.98% ） ,lowering 24.25% than the water control. However, the effect on preventing cracking of plastic film covering whose cracking rate is 16. 39% reaches extremely significant level （p-0. 01 ） as compared with the control, decreasing by 24. 83% than the cracking rate of the control.
