东北寒地水稻旱育取土难,破坏植被及耕层,水稻无土育苗基质是经过高温发酵处理代替育秧床土的一种新型的育秧技术,可以解决这些难题。为明确利用禾靓基质所育东北寒地水稻秧苗素质以及栽后水稻植株长势及成熟期产量,以中龙粳31为试验材料,在黑龙江省二九一农场实施禾靓基质育秧、营养土育秧(CK)对比试验,测定育成秧苗素质、返青生长和产量等,试验结果表明该基质可以促进水稻根系发育,提早返青生长。相比较常规营养土育苗,该基质育秧机插水稻主要通过增加有每穗总粒数17.88%和千粒质量1.13%,提高产量(增产20 kg/667m~2)。
It is difficult to remove soil and damage vegetation and tillage paddy in dry and cold paddy fields in Northeast China. Therefore, it is a new type of seedling raising technology that high-temperature fermentation process instead of seedling bed soil can solve these problems. In order to make full use of the quality of the rice seedlings grown in the cold plateau of northeast China and the yield and quality of the rice plants grown in Wo Liang matrix, Zhonglongjing 31 was used as experimental material to carry out Wo Liang matrix seedling raising and nutrition soil seedling growing in Heji Long Farm, (CK). The results showed that the substrate could promote the root development of rice and grow back to green earlier. Compared with the conventional nutrition soil, the matrix rice transplanting rice increased the yield (increased 20 kg / 667m ~ 2) by increasing the total grain number per panicle by 17.88% and the grain yield by 1.13%.
