以烤烟品种K326为材料,采用五因素五水平正交旋转组合设计,大田试验,电脑优化,建立了烤烟优质适产高效益栽培实用模型.产量在2250～2625kg/ha适产范围的最佳农艺措施组合为:每公顷施氮200.79～204.72kg.P2O5185.90～193.93kg,K2O316.88～357.30kg,单株留有效叶16片,移栽苗龄9叶1心.

The stimulation quadratic regression models of yield and value of flue -cured tobacco (Nicotiana tabacum L.)were established by the experiments designed in orthogonal rotation combination of five factors and five levels.The optimal combination of agronomic measures for high quality and moderate yield (2250～2625 kg/ha) is. N 201～205 kg/ha,P_2O_5 186～194 kg/ha, K_2O 317～357 kg/ha,the number of the leaves left on t...
