摘要
2009-2011年,连续3a在霍邱县农业科学研究所的试验田内进行播种量对水稻旱育秧苗质的效应研究,与同龄水育秧苗质做比较分析,结果表明:(1)旱育秧苗床适宜播种量是40g/m2;(2)旱育秧比水育秧绿叶数少9.44%,百苗干重重5.82%,苗高低9.86%,根数少15.46%,根长短29.66%,单株分蘖数少4.23%。旱育秧矮化蹲实,组织结构紧密,根系爆发力强,秧苗素质优于水育秧。
We studied on the effect of sowing rates to upland seedling quality in a test - bed of agriculture science institute in Huoqiu between 2009 and 2011. Compared to peer water seedling, the results showed that： （ 1 ） the seedbed suitable sowing rate of upland seedling was 40g/m2 ; （2） upland seedling＂ green leaves were less 9.44% than water seedlings＇, the seedling dry weight per hundred more 5.82%, seedling hight lower 9.86%, root number less 15.46%, root length less 29.66%, tillers per plant less 4.23%. Upland seedling was short and strong, organization structure close, the root powerful explosive force, and the seedling quality better than water seedling.
