| 摘 要： | 通过对分蘖肥不同施用时期对水稻产量和品质的影响研究,结果表明,随着分蘖肥施用时期的后移,水稻生育期延迟;株高和空瘪率逐渐增加,穗长和褐变穗发病率逐渐降低,穗颈瘟逐渐增加,倒伏程度没有明显变化;水稻平方米穗数逐渐增加,而穗实粒数、结实率、千粒重和产量逐渐降低;水稻的垩白率和垩白度没有明显变化,精米率和整精米率逐渐降低。

| Abstract: | The results showed that with the delay of tillering fertilizer application,the growth period postponed accordingly and the length and brown ear occurrence rate decreased,but the blast infected seriously.The delay of tillering fertilizer also led to the increase of panicles/m2 and the reduction of grains per panicle,kernel set rate,1000-grian weight and yield.The polished rice rate and head rice rate decreased,but the chalky grain rate and chalkiness degree changed little. |
