【摘要】 为了解含锌生物有机肥在岩溶地区土壤上的施用效果,在大化县七百弄乡弄石屯对玉米进行不同肥料处理试验。结果表明,施用含锌生物有机肥,对玉米的产量、农艺性状、品质、经济效益有显著影响,其产量分别比对照、有机肥、化肥增产63.3%、25.3%、19.7%;千粒重分别增加20.3%、5.9%、3.8%,穗粒数分别增加32.4%、14.2%、7.0%,籽粒蛋白质含量分别提高26.9%、4.0%、10.8%,经济收入分别增加20.2%、15.0%、4.7%。因此,在岩溶地区土壤上施用含锌生物有机肥,可以明显改善玉米的农艺性状,提高产量和经济效益,增加收入,取得良好的生态效益。更多还原

【Abstract】 In order to know about the applying effects of biological organic fertilizer with Zn on soil in Karst area,the experiment of different fertilizer treatments was carried out in Nongshi of Qibainong townships in Dahua County.The results showed that biological organic fertilizer with Zn had an obvious effects on the yield,agronomic traits,quality and economic benefits of maize.The yield of maize by applying organic fertilizer with Zn increased by 63.3%,25.3% and 19.7% as compared with the control,organic fertilizer and chemical fertilizer,respectively,and the 1000-grain weight increased by 20.3%,5.9% and 3.8%,respectively,the grains per panicle increased by 32.4%,14.2% and 7.0%, respectively;and the protein content of grain increased by 26.9%,4.0% and 10.8%,respectively,moreover,the economic income increased by 20.2%,15.0% and 4.7%,respectively.It indicated that applying biological organic fertilizer with Zn in Karst area could improve the agronomic traits,yield and economic benefits of maize,increase the income of farmers and get a good ecological benefits.更多还原
