遮光对水稻生长发育及稻米品质的影响

Effect of Shading on Rice Growth and Quality

为探讨遮光处理条件下不同水稻品种生长发育和稻米品质的变化规律,以‘五优稻4号’‘、松粳9号’和‘龙稻18’为材料,通过盆栽试验,研究了遮光处理条件下不同水稻品种的株高、分蘖、叶龄、产量性状、稻米品质的变化。结果表明:遮光降低了株高、减少了叶龄、生育期缩短8～10天、单株干重和产量下降达到了极显著水平、食味值下降达到显著水平。

To discuss the change rule of rice growth and development and rice quality of different varieties under shading treatment,plant height,tillering,leaf age,yield character and rice quality of‘Wuyoudao 4’,‘Songjing 9’and‘Longdao 18’were analyzed by pot experiment.The results showed that shading reduced plant height and leaf age,shortened the growth period by 8-10 days,dry weight per plant and yield decreased by an extremely significant level,taste value decreased by a significant level.
