- 摘要:
- 为明确气象条件对甜高粱农艺性状的影响，在气象条件差异较大的2008年和2009年，对30份不同性状的国内外甜高粱材料进行农艺性状调查研究，结合气象条件分析，结果表明：各性状年度间的变化主要是由于年度间不同的气候条件造成的，温度、降水量、日照时数和温差对出苗至开花日数、生育日数、株高、单穗重、千粒重、糖分积累影响较大；茎粗和分蘖数不受气象因素的影响，而由品种本身特性及种植密度、田间管理等因素决定。
- Abstract:
- To confirm the effect of weather conditions on characters of sweet sorghum，the agronomic research on 30 sweet sorghum samples with different characters bred at home and broad were studied in 2008 and 2009 with quite diverse weather conditions.The results showed that the annual variation of each character was mainly due to different climatic conditions in different year.Temperature，precipitation，sunshine hours and temperature variation largely affected the number of days from emergence to flowering，growth days，plant height，single spike weight，grain weight and sugar accumulation;Stem diameter and number of tillers were not affected by the meteorological factors，but affected by their own characteristics and planting density，field management and other factors.
