- Title:
- Study on Yield-Increase Model of Winter Wheat on Loess Rainfed Highland
- 摘要:
- 1984-1986年,在陕西省蒲城县设置了二组三因素五水平旋转设计试验,对影响小麦产量的施肥(包括氮肥、磷肥、有机肥)播期、播量等主要因素加以综合研究.建立了黄土旱塬地区冬小麦增产栽培措施的二个主要模式方程和多个因素之间交互作用的若干子模式方程.根据试验结果利用计算机田间模拟寻优得出该地区小麦亩产250-300kg丰产组合方案,根据这些模式方程和所得到125×2的不同因素相配合下的不同产量水平,因地制宜地制定秋播措施方案,用来指导生产、预测产量.
- Abstract:
- In 1984-1986,two field experimentals of winter wheat with 3 factors 5 levels of universal rotation design were carried out in Bucahang County of Shanxi Province.Based on experimental results,a series of models had been established,which includes two main models:N fertilizer-P fertilizer-organic fertilizer,and sowing date-sowing rate-N fertilizer related with yield components and grain yield etc.,using these models,one can know how to adpot the optimum sowing practices in autumn,to predict yield and to exam the effect of cultivation practices,so as to achieve the optimum yield increase under the different conditions.
