摘要:

以南粳9108为试验材料,设置2个低播种量(90 g/盘和110 g/盘)和3种拌种剂(旱育保姆、咪鲜·甲霜灵和苗壮丰)处理,研究稀播和拌种剂对毯苗机插水稻不同秧龄期秧苗素质的影响,旨在探究毯苗机插水稻长秧龄壮秧培育的关键技术。结果表明,在稀播和拌种剂处理下,毯苗机插水稻秧龄25 d的秧苗素质最好;播种量90 g/盘的秧苗素质好于110 g/盘;3种拌种剂对秧苗素质均有不同程度的优化调节作用,其中,旱育保姆拌种剂处理的秧苗素质在苗高、叶龄、白根数、根长、茎基宽、发根力等方面效果较好。

Abstract:

In order to explore the key techniques of cultivating strong seedlings with longer leaf age for carpet seedlings mechanical transplanted rice, an experiment was conducted to study the effects of sparse sowing and seed-dressing agent on seedling quality of machine-transplanted rice with carpet seedlings, using Nangeng 9108 as material, two low seeding rates (90 g/tray and 110 g/tray) and three seed-dressing agent (hanyubaomu, mixian·jiashuangling and miaozhuangfeng) treatments were set. The results showed that the quality of rice seedlings transplanted with blanket seedling machine for 25 days of age was the best under the treatment of sparse sowing and seed-dressing agent. The seedling quality of the treatment with sowing amount of 90 g/tray treatment was better than that of 110 g/tray treatment. The three kinds of seed dressing agents had different degrees of optimization and regulation adjustment effects on the quality of seedlings. Among them, the quality of the seedlings treated with Hanyubaomu was the best in terms of seedling height, leaf age, white root number, root length, basal diameter, rooting power.
