【摘要】 [目的]为夏花生规范化栽培提供科学依据。[方法]采用5因素二次回归正交旋转设计,研究施氮量、播期、密度、化控量及叶面喷硼5项栽培措施与夏花生产量的关系。通过模拟寻优,找出了综合栽培措施决策方案。[结果]建立了豫东平原夏直播花生综合栽培措施的产量数学模型,复相关系数为0.944 5,达极显著水平。5项栽培措施对产量的一次项效应是播期>密度>施氮量>多效唑>硼砂;二次项的效应为密度>施氮量>多效唑>播期>硼砂。5个因素95%置信域的最佳组合值是:施氮量169.9~192.2 kg/hm2,播期6月7日~9日,密度30.7万~31.7万株/hm2,多效唑920.6~965.4 g/hm2,硼砂1 159.2~1 325.4 g/hm2。[结论]模拟寻优的方案比经验方案增产13.1%。更多还原

【Abstract】 [Objective] The study was to provide the scientific basis for standardized cultivation of summer peanut.[Method] 5 factors quadratic regression orthogonal rotating design was used to study the relationships between yields and 5 cultivation measures of summer peanut such as nitrogen rate,sowing date,density, chemistry control amount and leaf spraying B.The decision scheme of comprehensive cultivation measures was found by simulating optimization.[Result] The yield mathematical model with comprehensive cultivation measures of summer peanut in Yudong plain was established,the multiple correlation coefficient was 0.944 5 and achieved extremely significant level.The monomial effects of the 5 cultivation measures to on the yield in order were sowing date>density>nitrogen rate> paclobutrazol > borax.The quadratic effects were density>nitrogen rate> paclobutrazol >sowing date > borax.The best combination value of 95% confidence region of the 5 factors were that nitrogen rate was 169.9-192.2 kg/hm2,the sowing date 7th to 9th,June,density 30.7×104-31.7×104 strains/hm2,paclobutrazol 920.6-965.4 g/hm2 and borax 1 159.2-1 325.4 g/hm2.[Conclusion] The yield in scheme of simulating optimization was 1 3.1% higher than that of in experienced method.更多还原
