以辽宁省2007年中晚熟水稻区域试验参试品种为分析材料,分析了不同试验点产量水平、不同产量水平产量及产量结构的差异,不同试验点高产品种产量及产量结构差异。结果表明,选择适宜的高产品种对各生态区水稻产量有重要影响,在不同生态区水稻增产途径有一定的差异,辽阳、鞍山、海城、沈阳农大试区更适宜种植穗数、穗粒兼顾型高产品种,大石桥、辽宁省盐碱地所、西海试区更适宜种植穗数型高产品种,辽宁省稻作所试区更适宜种植穗重型高产品种。
Taking the medium and late-maturing rice regional trial varieties tested in 2007 in Liaoning Province as the experimental materials, the differences of yield, yield and yield structure at different test sites were analyzed. The yield and yield structure differences of high-yielding cultivars at different test sites were analyzed. The results showed that selecting suitable high-yielding varieties had an important influence on the yield of rice in each ecological zone, and there were some differences in the yield-increasing ways of rice in different ecological zones. It is more suitable for the cultivation of spikelets, grains and kernels in Liaonan, Anshan, Haicheng and Shenyang Agricultural Experimental Areas Type high-yielding varieties, Dashiqiao, Liaoning Province saline-alkali land, the West China Sea area is more suitable for the cultivation of spike-type high-yielding varieties, Liaoning Province, rice-growing areas more suitable for the cultivation of high-yielding spike varieties.
