中文摘要:
      为研究不同光照条件下紫叶观赏稻茎、叶、分蘖等性状的生长差异,制定紫叶观赏稻种植技术,拓宽其应用途径。选取叶 色为紫色的观赏稻品种B151和GY7作为试验材料,模拟家居庭院光照条件,设置正常光照、遮阳网下和墙边3个光照处理,以 及分蘖前期和分蘖中后期2个移动时间处理。通过对叶色、叶片数、叶面积、剑叶性状、分蘖、有效穗、株高、抗逆性等性状数据 的分析,结果表明:正常光照时间的缩短和光照强度的减弱,导致紫叶观赏稻分蘖数、叶片数、有效穗减少,叶片紫色变浅,剑叶 长宽增加,剑叶夹角增大,叶片披垂,稻株仍具有较强的观赏性,适宜在家居庭院中种植。
英文摘要:
      Two purple-leaf rice varieties (B151 and GY7) were selected as experimental material to discuss the growth variation of purple-leaf rice in different light conditions, so that we can make purple-leaf visual rice planting techniques and broaden application path. The light conditions of home and garden are simulated, and set three light treatments and two processing in time. We studied the effects of diverse light conditions on leaf color, leaf number, leaf area, flag leaf traits, tillering, effective panicle, plant length and stress resistance. The results show that the shortening of natural light time and the decreasing of light intensity leads to fewer tillering and leave number, lighter purple-leaf and effective panicle, and the length, width and angle of flag leaf increased. To sum up, purple-leaf visual rice plants still have extremely visual value, and can be planted in home and garden.
