采用回归正交旋转设计的方法,研究提出播种期、播种量、氮肥、磷肥用量对水、旱地胡麻增产作用的大小因种植土壤的水分条件而不同。多施磷肥、氮磷配施是水地胡麻高产的关键;抢墒抓苗、提高资源利用率是旱地胡麻高产的关键。通过对产量模型和毛收益模型的解析,求出了高产量、高利润及不同产量范围内的最适农艺组合措施。
The method of regression orthogonal rotation design was used to study the effects of sowing date, sowing amount, nitrogen fertilizer and phosphate fertilizer on the yield increase of flax in water and dry land because of different soil moisture conditions. Multi-application of phosphorus, nitrogen and phosphorus facilities is the key to high-yield flax seedlings; grab moisture grasping seedlings, improve resource utilization is the key to high-yield dry land flax. Through the analysis of the yield model and the gross profit model, the optimum agronomic combination measures in high yields, high profits and different yields were obtained.
