摘要
本文采用二次饱和D—最优设计方法,通过1986—1987两年三个试验,探求分析了旱地栽培条件下,胡麻产量与播种量、氮肥,磷肥之间的关系。并通过产量模型和经济效益模型的分析,明确了当前生产条件下,以高产和高利润为目标时,播种量、氮肥、磷肥的适宜用量,为生产中选择提供了依据。
Based on three experiments held in 1986-1987, using the two power saturation D-best design methed, the relationship of seedflax yield, the sowing quantity of seedflax, the amount of N-fertilizer and P_2O_5-fertilizer applied under the condition of dryland cultivation were probed and analysed. Through analysing the yield and economic profit models, the appropriate norm for seed sowing and fertilizer spreading was determined.
