水稻无纺布(蛇皮袋)育秧抛栽试验研究

2006年,以早稻优Ⅰ54、晚稻博优938为材料,在钦州市进行水稻无纺布(蛇皮袋)育秧试验,结果表明,水稻无纺布(蛇皮袋)育秧抛栽具有省种、省工、免用秧盘的优点,增产增收效果明显。早稻每公顷产量比对照(塑盘育秧)增产399kg,增长8.3%;晚稻每公顷产量比对照增产489kg,增长7.8%,比迟播10d的塑盘育秧抛栽增产699kg,增长11.6%。增产的主要原因是无纺布(蛇皮袋)育秧大大地提高了水稻的秧苗素质,在假茎高、假茎宽、单株根数和秧苗分蘖率等方面均优于对照,特别是秧苗分蘖率,优势更加明显,抛后分蘖早、分蘖多、够苗早。由于无纺布(蛇皮袋)育秧可以适当提早播种,对延长水稻的营养生长期,增加干物质积累,对晚稻培育适龄老壮秧、抢季节、避免“寒露风”危害更为有利。

Experiment on rice seedling raising on non-woven fabric colthes for seedling-broadcast cultivation

Seedlings of early rice You I 54 and late rice Boyou 938 were raised on non-woven fabric clothes in Qinzhou City in 2006.The results showed that the seedling raising techniques is characterized by saving seeds,labors and seedling plastic pot,with the yield and income increasing significantly.Applying non-woven fabric clothes to raise seedlings,the yield of early rice increased 399kg/hm2 with increasing rate of 8.3%,as compared to the control (seedling raising with plastic pot),and that of late rice increased 489kg/hm2 with increasing rate of 7.8%.The yield increased 699kg/hm2 with increasing rate of 11.6%,as compared to the treatment for 10 days later broadcast in late rice.The main causes for yield increasing was that raising on non-woven fabric clothes could improve rice seedling quality,increase the height and width of pseudostem,the number of root per plant and especially the tillering ability of seedling.The seedling was higher than the control,its tillering was earlier and much more,and the enough total number of tillers in the field could be reached earlier.Because of earlier broadcasting,seedling raising on non-woven fabric clothes could be more favor of elongating the vegetative growth of rice and increasing the accumulation of dry matter,which is suitable in raising vigorous old seedling ahead of season to avoid the damage of cold dew wind for later rice.
