摘要/Abstract

摘要：

为明确浙东南地区不同类型优质稻的适宜播期,以籼粳杂交稻甬优1540和杂交籼稻泰两优217为材料,开展大田分期播种试验,研究5个不同播期(Ⅰ~Ⅴ期)对水稻产量及其构成因素、生育期、秧苗素质、分蘖特性、群体生长率、干物质积累和稻米品质的影响,并分析水稻产量、品质与气候因子之间的相关性。结果表明:随播期推迟,甬优1540和泰两优217产量先增后减,分别以第Ⅱ期和第Ⅲ期最高,其对应的产量潜力分别为11.54和9.47 t·hm^-2;其构成因素的变化趋势与产量变化基本一致。生育时期随播期推迟而相应顺延,播种-齐穗期缩短,齐穗-成熟期延长,全生育期变化因品种而异。随播期推迟,秧苗素质、干物质积累和收获指数先提高后降低,分蘖数上升而成穗率下降,群体生长率和茎叶输出率因品种、生育阶段不同而存在差异。播期主要影响稻米的加工和外观品质,其品质总体随播期推迟呈变优的趋势。产量与齐穗-成熟期的温光资源显著或极显著正相关,而品质与齐穗20 d至成熟期的温光资源关系密切。综上,在该地区甬优1540高产与优质同步的播期为5月7日至5月26日;泰两优217高产且相对优质的播期为5月16日至5月22日,而优质且相对高产的播期为5月23日至5月27日。

Abstract:

To determine the suitable sowing dates for high quality rice of different types in Southeastern Zhejiang, a field interval sowing experiment was carried out with indica-japonica hybrid rice Yongyou 1540 and indica hybrid rice Tailiangyou 217. The effects of different sowing dates (Ⅰ-Ⅴstage) on grain yield and its components, growth period, seedling quality, tillering characteristics, population growth rate, dry matter accumulation, and rice quality were studied, and the correlation between grain yield and climatic factors, quality and climatic factors was analyzed. The results showed that the grain yield of Yongyou 1540 and Tailiangyou 217 increased first and then decreased with the delay of sowing date, and the yield potential was 11.54 t·hm^-2 for Yongyou 1540 in stage Ⅱ and 9.47 t·hm^-2 for Tailiangyou 217 in stage Ⅲ. The change trend of yield components was basically consistent with the yield change. The growth stages of rice were delayed with the delay of sowing date. Sowing-heading period was shortened, whereas heading-maturing stage was extended, and the change of whole growth period varied with cultivars. With the delay of sowing date, the seedling quality, dry matter accumulation, and harvest index increased first and then decreased, while the tiller number increased and the productive tiller percentage decreased, and the population growth rate and the output rate of dry matter of stem and leaf varied with cultivars and growth stages. The sowing date mainly affected the rice milling and appearance quality. Rice quality was improved with the delay of sowing date. The grain yield was significantly or extremely significantly positively correlated with the resources of temperature and sunshine during the full heading-maturing stage, while the quality was closely related to temperature and sunshine resources from the 20th day after full heading to maturing stage. We recommend the best sowing date for Yongyou 1540 could be from May 7 to May 26. The sowing date for Tailiangyou 217 with high yield and relatively high quality could be from May 16 to May 22, while the sowing date for Tailiangyou 217 with high quality and relatively high yield could be from May 23 to May 27.
