2009年在三江侗族自治县以Y两优3218为材料,开展水稻无盘湿润育秧旱育保姆不同剂量拌种对比试验,设每千克种子拌旱育保姆250,300,350,400,450 g 5个处理。结果表明:水稻苗高、假茎高和第1叶鞘高度与旱育保姆拌种剂量呈负相关,假茎宽、叶龄、单株总根数、白根数和白根率与旱育保姆拌种剂量呈正相关,秧苗干物质积累量以350 g处理为最高;产量以350 g处理为最高,300 g处理次之。综合来看,桂北高寒山区水稻无盘湿润育秧每千克种子的适宜旱育保姆拌种剂量为300～350 g,最高不应超过400 g,即在生产上以旱育保姆1袋(350 g)拌稻种1.00～1.17 kg为宜,最低拌种量不应少于0.88 kg。
2009 in Sanjiang Dong Autonomous County to Y Liangyou 3218 as a material to carry out the rice without disk wet nursery nursery dry nursery different doses of seed dressing contrast test, set per kilogram seed mix dry nurse nanny 250,300,350,400,450 g 5 treatment. The results showed that the seedling height, pseudostem height and leaf sheath height were negatively correlated with the dry-nurse nanny seed dressing dose. The width of pseudostem, leaf age, total number of roots, The dose was positively correlated, and the dry matter accumulation of seedlings was the highest at 350 g. The yield was the highest at 350 g and the second at 300 g. Taken together, the optimum drought-tolerant nanny seed dressing dosage per kilogram of seedlings for paddy-free rice seedling cultivation in high and cold mountainous areas of northern Guangxi is 300-350 g and the highest should not exceed 400 g, that is, 1 bag of dry nanny ) Mixing rice 1.00 ~ 1.17 kg is appropriate, the minimum seed dressing should not be less than 0.88 kg.
