| 摘 要： | 基于投影寻踪分类模型,以建三江大兴实验指标用水量、产量、水分生产率、生产成本、其他费用、耗电量、施肥量、农药用量及倒伏率为评价指标,对控制灌溉进行经济效益评价。结果表明,控灌Ⅰ投影值最佳,通过投影值得经济效益最优的处理为控制灌溉Ⅰ,控制灌溉Ⅱ与控制灌溉Ⅲ次之,然后是示范区及辐射区,最后是常规灌溉。同时控灌Ⅰ处理产量最高,达到10 400.55 kg/hm~2;控灌Ⅰ与常规灌溉相比,每公顷可节水899.85 m3,最高水分生产效率达2.397 kg/m3。研究成果为节水增产,为实际生产提供指导。

Projection Pursuit Evaluation Mode for Economic Benefits of Rice Water-Saving Control Irrigation |
| |
| Abstract: | Based on the projection pursuit classification model, taking water consumption, yield, water productivity, production cost, other cost, power consumption, fertilizer dosage, pesticides and lodging rate as the evaluation index, the economic benefit evaluation of rice control irrigation is conducted.The results show that the projection value of controlling Ⅰ treatment is the best, so the economic benefit of controlling irrigation Ⅰ treatment is the best, followed by controlling irrigation Ⅱ treatment, controlling irrigation Ⅲ treatment, demonstration zone and conventional irrigation treatment;the yield of controlling irrigation Ⅰ treatment is the highest and reaches 10 400.55 kg/hm 2;compared with conventional irrigation, controlling irrigation Ⅰ treatment can save water by 899.85 m 3 per hectare;the highest water production efficiency can reach 2.397 kg/m 3.The research results can provide basis for the popularization and practical application of rice controlling irrigation technology. |
