将滇杂46种植在辽宁中部、东南沿海稻区和北部稻区,分析滇杂46在辽宁各地种植后干物质、SPAD值、LAI值、产量及其构成因素、米质的差异,结果表明,滇杂46的干物质积累量、有效穗、千粒重、穗长、株高大于辽优5206;茎叶干物质转移量、转移率、SPAD值、LAI值、结实率和产量小于辽优5206;米质明显差于辽优5206;滇杂46种植在辽宁3个地区和种植在云南比较,株高变高,产量下降,糙米率、整精米率也下降,种植在辽宁东南沿海稻区(庄河)的千粒重和结实率要高于种植在云南,产量也更接近。
The Dianza 46 was planted in central Liaoning, southeast coastal rice area and northern rice area. The differences of dry matter, SPAD value, LAI value, yield, composition and quality of Dianza 46 after planting in Liaoning Province were analyzed. Dry matter accumulation, effective panicle, 1000-grain weight, spike length and plant height of Dianza 46 were higher than those of Liaoyou 5206; dry matter translocation, translocation, SPAD, LAI, seed setting rate and yield of stem and leaf were less than that of Liaoyou 5206; Compared with Liaoyuan 5206, Dianza 46 was planted in three areas of Liaoning Province and compared with that of Yunnan in Yunnan Province. The plant height became higher and the yield decreased. The percentage of brown rice and holm rice also decreased. ) 1000-grain weight and seed setting rate is higher than planting in Yunnan, the yield is closer.
