本文采用近代回归方法所得的多因子试验研究结果表明:旱地谷子产量与苗数、农肥、化肥、施肥深度、保墒次数呈显著相关关系,各因子的权重顺序为施肥深度>保墒次数>苗数>化肥>农肥;多因子优化组合的累加效应显著大于简单;相加效应;所建立的高产优化栽培模式具有很大的增产潜力,并得到了实践验证。
The results of multi-factor experiments using modern regression methods showed that the yield of dry millet millet was significantly correlated with the number of seedlings, the amount of agricultural fertilizer, chemical fertilizer, fertilization depth and the number of preserving moisture. The order of weight of each factor was fertilization depth> number of soil conservation> seedling> Chemical fertilizer> agricultural fertilizer; the cumulative effect of multi-factor optimization combination is significantly greater than simple; additive effect; and the established high-yield and optimized cultivation mode has a great yield potential and has been proved by practice.
