[目的]在目前推广的水稻膜下滴灌旱作种植方式基础上,在寒地研究其水肥一体化技术,提出高产高效水肥优化组合方案,为膜下滴灌水稻栽培技术推广应用提供配套的水肥管理技术参考和理论依据。[方法]以龙粳31号和空育131为材料,采用随机区组试验设计,研究膜下滴灌水肥耦合对寒地水稻产量构成因素及产量的影响。[结果]膜下滴灌以体积含水量降至饱和含水量的80%为控水下限的水分管理、分蘖肥与穗肥用量分别为87,15kg/hm2的处理能够增加两品种的穗数/m2;膜下滴灌的两种水分、肥料处理对两品种穗粒数的影响不显著。膜下滴灌处理以体积含水量降至饱和含水量的80%为控水下限的水分管理其生物产量、经济系数和经济产量高于以体积含水量降至饱和含水量的60%为控水下限的水分管理,两品种的表现为一致的。膜下滴灌以体积含水量降至饱和含水量的60%为控水下限的水分管理,同时分蘖肥与穗肥用量分别为70,12kg/hm2的处理两品种的经济产量均为最低。空育131以体积含水量降至饱和含水量的80%为控水下限的水分管理,同时分蘖肥与穗肥用量分别为87,15kg/hm2的处理最适合膜下滴灌旱种;龙粳31号以体积含水量降至饱和含水量的80%为控水下限的水分管理,同时分蘖肥与穗肥用量分别为70,12kg/hm2的处理最适合膜下滴灌旱种。[结论]不同品种对膜下滴灌水肥耦合的反应不同,膜下滴灌旱种处理水肥耦合对寒地水稻产量有重要影响。 [Objective] Based on the current popularization plan of drip irrigation under film in paddy field, the paper studied the integration of water and fertilizer in cold area and put forward the plan of combination of high yield and high efficiency of water and fertilizers to provide water and fertilizer management for the popularization and application of rice drip irrigation Technical reference and theoretical basis. [Method] With Longjing 31 and Kongyu 131 as materials, a randomized block design was used to study the effects of water and fertilizer coupling under drip irrigation on the yield components and yield of cold paddy rice. [Result] Under the condition of drip irrigation under drip irrigation, the volumetric water content decreased to 80% of the saturated water content as the water management with the lower limit of water control. The treatment of tillering fertilizer and panicle fertilizer at 87 and 15 kg / hm2 could increase the number of spikes / m2 ; The two kinds of drip irrigation under water and fertilizer had no significant effect on the number of grains per spike. Underwater drip irrigation treatment with volumetric water content down to 80% of saturated water content as the water control lower limit of water management The biological yield, economic coefficient and economic output is higher than the volumetric water content to 60% of saturated water content as the control water lower limit The water management, the performance of the two varieties is the same. Under the film drip irrigation, the volumetric water content decreased to 60% of the saturated water content as the water management of the lower water control limit, while the economic yield of the two varieties with the tillering fertilizer and the panicle fertilizer being 70 and 12 kg / hm2 respectively was the lowest. In Kongyu 131, the volumetric water content decreased to 80% of the saturated water content as the water management with the lower limit of water control, while the treatment of tillering fertilizer and panicle fertilizer at 87 and 15 kg / hm2 was the most suitable for the dry film drip irrigation. The volumetric water content decreased to 80% of the saturated water content as the water management of the lower water control limit, and the treatment of tillering fertilizer and panicle fertilizer were 70 and 12 kg / hm2 respectively. [Conclusion] The responses of water and fertilizer to different drip irrigation under different varieties were different. The effects of water and fertilizer coupling under dry film drip irrigation on the yield of rice in cold area were significant.
