本研究采用四因子回归最优混合设计 ,对杂交玉米新品种临奥一号 N、P、K不同配方施用量及不同密度进行了试验 ,在测得参数的基础上建立了数学模型。经解析 ,确定了高产栽培措施置信区间 ,优选出最佳组合方案为 :6 6 7m2 施尿素 2 9～30 .2公斤 ,普钙 33～ 34公斤 ,氯化钾 18～ 18.6公斤 ,密度2 86 0～ 2 90 0株。在育苗定向移栽 (3.1～ 4 .1叶 ) ,6 6 7m2施优质农家肥 15 0 0公斤的条件下 ,三薅三追 ,防治病虫害 ,可望获得 6 6 7m2 产 5 0 0 kg以上的产量。结合生产经验 ,提出了临奥一号规范化栽培决策
In this study, the optimum mixed design of four factors regression was used to test the application rates and different densities of N, P, and K different varieties of hybrid maize cultivar Linyou No.1. Based on the measured parameters, a mathematical model was established. After the analysis, the confidence intervals of high yielding cultivation measures were determined, and the optimal combination plan was as follows: 6 6 7m2 urea 29 ~ 30.2 kg urea, calcium 33 ~ 34 kg, potassium chloride 18 ~ 18.6 kg, density 286 0 to 2 90 0 strains. Under the condition of directional transplanting of seedlings (3.1-4.1 leaves) and applying of 600 kg of high-quality peasant fertilizer at 156 kg / m2, it is possible to obtain more than 500 kg of 6 6 7 m 2 Yield. Combined with production experience, put forward the Pro-Olympic standardized cultivation decision-making
