水浇地一地三收模式选择及效益分析

Benefit Analysis of High-efficient Planting Patterns for Reaping Three Times for One Plot on the Irrigated Land

对辽宁西部地区水浇地进行一地三收模式试验研究,结果表明:玉米/蹲豆×芸豆模式的总产量为2038kg/667m2,总产值为1730元/667m2,总效益为1380元/667m2;西瓜/辣椒—早熟玉米模式的总产量为2975kg/667m2,总产值为1700元/667m2,总效益为1333元/667m2;玉米/马铃薯×芸豆模式的总产量为3038kg/667m2,总产值为1680元/667m2,总效益为1300元/667m2;玉米/小豆×芸豆模式的总产量为1603kg/667m2,总产值为1360元/667m2,总效益为1035元/667m2。要获得最大收益,以玉米为主产的水浇地应首选玉米/蹲豆×芸豆模式,其次选玉米/马铃薯×芸豆模式;以西瓜为主产的水浇地,应选西瓜/辣椒—早熟玉米模式。

An experiment of reaping three times for one plot was conducted on the irrigated land in western Liaoning province. The result shows that the total output of maize/squatting beanxkidney bean is 2 038 kg/667 m2 the total value is 1 730 RMB/667 m2 the total benefits is 1 380 RMB/667 m2, the total yields of watermelon/pepper-early-matured maize is 2 975 kg/667 m2 the total value is 1 700 RMB/ 667 m2 the total benefits is 1 333 RMB/667 m2, the total yields of maize/potatoxkidney bean is 3 038 kg/667 m% the total value is 1 680 RMB/667 m2, the total benefits is 1 300 RMB/667 m2, and the total yields of maize/adzuki beanxkidney bean is 1 603 kg/667 m2 the total value is 1 360 RMB/667 m2, the total benefits is 1 035 RMB/667 m2. In conclusion, if maize is taken as the main product, the most efficient planting pattern is maize/squatting beanxkidney bean, maize/potatoxkidney bean coming next, and if watermelon is taken as the main product, the best pattern is watermelon/pepper-early-matured maize.
