摘  要：
为探明不同锌肥用量及施用方法对朝天椒预防病毒病及产量的影响,选取潜在性缺锌(土壤有效锌含量0.76 mg/kg)的石灰性土壤,对常规朝天椒品种日本新一代三樱椒,进行3个施锌方法(土壤施锌、叶面喷锌、土壤施锌+叶面喷锌)和4个土壤施锌量(0,15,30,45 kg/hm~2 ZnSO_4·7H_2O)处理的田间试验。结果表明,施用锌肥各处理产量均高于对照(不施锌肥),各处理较对照增产5.78%~13.25%,产量先随施锌量的增加而增加,超过一定用量后反而降低;锌肥的施用方法对朝天椒的产量有显著影响,锌肥土施、叶面喷施均可显著提高朝天椒的产量,以"土施+叶面喷施"增产效果最好;不同锌肥用量及施用方法对朝天椒病毒病均有较好的防治效果(47.59%~76.12%),全生育期可将病情指数控制在较低范围内。在潜在性缺锌的石灰性土壤上,朝天椒锌肥土施结合叶面喷施,具有明显的防病增产作用,七水硫酸锌(ZnSO_4·7H_2O)以土壤基施30 kg/hm~2+叶面喷施7.5 kg/hm~2(分为3次)效果最佳。

摘  要：
To investigate the effect of different dosage and application methods of zinc fertilizer on the prevention of virus disease and the yield of pod pepper, the potential zinc deficiency(soil effective zinc content 0.76 mg/kg)was selected for calcareous soil, in this paper, 3 methods of zinc application(soil zinc, foliar zinc, soil zinc + foliar zinc), and the amount of zinc applied in 4 soils(0, 15, 30,45 kg/hm~2 ZnSO_4·7 H_2O)were carried out for a new generation of three cherry peppers in Japan. The results showed that the yield of zinc fertilizer was higher than that of the control(no Zn fertilizer), and the yield increased by 5.78%-13.25%, the yield increased with the increase of zinc application, and then decreased after a certain dosage. The application method of Zn fertilizer had a significant effect on the yield of pod pepper, and the yield of the pod pepper could be significantly improved by applying zinc fertilizer and foliar spraying. The different dosage and application methods of zinc fertilizer had better control effect(47.59%-76.12%), and the disease index was controlled in the lower range during the whole growth period. In the calcareous soil of latent zinc deficiency, the combination of foliar spraying with zinc-soil in the pepper can obviously prevent and increase the effect of preventing and controlling, and the seven-water zinc sulfate(ZnSO_4·7 H_2O)is sprayed on the soil base 30 kg/hm~2+foliar 7.5 kg/hm~2(3 times)has the best effect.
