| 摘 要： | 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。

| Abstract: | The effects of sowing date, sowing norm, and the amounts of nitrogen or phosphorus fertilizers on seedflax yield varied with the soil moisture.On the irrigated field, the key of improving seedflax yield was the use of more phosphorus fertilizer and the reasonable combining of nitrogen and phosphorus fertilizers, while on the dryland, it was losing no time in sowing while there was sufficient moisture in the soil, preserving the seedling, and improving the utilization ratio of resources.Through analysing the yield and economic profit models, the appropriate agronomic comprehensive practice was determined. |
