摘要
为进一步明确中宁县大豆玉米带状复合种植“4:3”模式下,玉米、大豆控释肥最佳施用量,采用随机区组试验设计,共设置玉米控释肥47%(30-12-5)施用量80 kg/667m^(2)、大豆控释肥55%(21-24-10)20 kg/667m^(2);玉米控释肥72 kg/667m^(2)、大豆控释肥12 kg/667m^(2);玉米控释肥64 kg/667m^(2)、大豆控释肥6 kg/667m^(2);玉米控释肥56 kg/667m^(2)、大豆控释肥0 kg/667m^(2)4个处理,分析不同施肥处理对玉米大豆的产量及产量构成、经济效益影响。结果表明:玉米控释肥72 kg/667m^(2)、大豆控释肥12 kg/667m^(2)的施肥方案最佳,此施肥方案条件下玉米产量为599.49 kg/667m^(2),大豆产量为40.09 kg/667m^(2),种植效益42.97元/667m^(2)显著高于其他处理。中宁县大豆玉米生产上采用玉米控释肥72 kg/667m^(2)、大豆控释肥12 kg/667m^(2)的施肥方案,产量效益最佳。
To further clarify the optimal application rate of controlled-release fertilizer for corn and soybean under the"4:3"strip intercropping mode in Zhongning County,an experimental layout was employed,adopting a randomized block design.Four treatment options were established:80 kg/667m^(2) of corn controlled-release fertilizer 47%(30-12-5)and 20 kg/667m^(2) of soybean controlled-release fertilizer 55%(21-24-10);72 kg/667m^(2) of corn controlled-release fertilizer and 12 kg/667m^(2) of soybean controlled-release fertilizer;64 kg/667m^(2) of corn controlled-release fertilizer and 6 kg/667m^(2) of soybean controlled-release fertilizer;56 kg/667m^(2) of corn controlled-release fertilizer and 0 kg/667m^(2) of soybean controlled-release fertilizer.The impacts of different fertilizer application treatments on the yield,yield components,and economic benefits of corn and soybean were analyzed.The results showed that the fertilizer application scheme of corn controlled-release fertilizer 72 kg/667m^(2) and soybean controlled-release fertilizer12 kg/667m^(2) was the best.Under this scheme,the corn yield was 599.49 kg/667m^(2),the soybean yield was 40.09 kg/667m^(2),and the planting benefit of 42.97 yuan/667m^(2) was significantly higher than other treatments.The fertilizer application scheme of corn controlled-release fertilizer 72 kg/667m^(2) and soybean controlled-release fertilizer 12 kg/667m^(2) is optiminal for corn and soybean production in Zhongning County,achieving the optimal yield and economic benefits.
