机插水稻不同育秧基质应用效果初探

摘要

为探明机插水稻不同育秧基质应用效果，以营养土育秧为对照，比较研究了江苏沃野、常州立华、连云港恒奥达、兴化新土源和南通瑞华等5个品牌基质育秧效果。结果表明，几种育秧基质所育秧苗叶色明显浅于对照，秧苗素质也比对照差，但盘根效果要好于对照。移栽大田后，基质育秧活棵、发苗要慢于营养土育秧，最终实产除常州立华和兴化新土源与对照相差不大外，其余3种育秧基质处理明显低于对照。%Comparing the application effects on machine-transplanted rice of different seedling substrates, with nutrient soil seedling as control. The results showed that the leaf color of seedling substrates treatment significantly shallower than nutrient soil treatment, seedling quality is poorer. But the matrix seedling root is better. The survival rate and seedlings is slow than the nutrient soil seedling treatment after transplanting in field. The final yield of nutrient soil seedling, Changzhou Lihua and Xinghua xintuyuan are almost the same, and the yield of the other substrates are relatively low.
