| 摘要: |
| 研究带侧向深施肥装置的水稻多功能插秧机（插秧施肥方式）在我国南方水稻与油菜轮作区的应用效果。以常规种植方式为对照组，设计4种肥料减施方案，监测水稻生长过程和产量的关键指标，并对其经济性进行分析。结果表明：相比常规种植方式，插秧施肥方式能够提高成穗数、穗粒数和千粒重，增产约6%。合理的肥料减施率为30%，平均每hm2增加利润1 654.95元。插秧施肥方式在增产增效方面效果显著，可优先在合作社或种植大户中推广使用。 |

| Abstract: |
| With the aim to test the effect of deep side fertilizing with multifunctional rice transplanter in rice-rape rotation areas in Southern China,taking traditional planting method as the control group,4 treatments of reducing fertilizer application were designed in the field trials.The critical data of rice growing and yield were collected,and economic analysis was conducted as well.The results showed that the method of transplanting with deep side fertilizing could increase panicles,grains per panicle and 1 000-grain weight.The general yield increased about 6%.Reasonable reduction rate of fertilizer applied was 30% with an average increased profit of 1 654.95 yuan per hm2.The test shows the remarkable effect of deep side fertilizing on increasing the yield and income,which can be promoted in cooperatives and leading growers at the beginning. |
