摘要
0.3 g/L低聚壳聚糖水剂是一种新型植物生长调节剂。通过在水稻苗期和秧田期使用该水剂,探讨其对水稻生长及产量的影响。结果表明:0.3 g/L低聚壳聚糖水剂可促进水稻根系发育和分蘖;增加千粒重,提高产量;对恶苗病防效达48%。其较佳使用方法为苗期浇灌,移栽返青后茎叶喷雾。
Chitooligosaccharide is a new kind of product which can adjust plant s growth.The result showed that Chitooligosaccharide can promote root development,minute tiller,weight of athousand seeds and rice output by sprayed the leaf.It controlled efficiencies of Fusarium moniliforme reached 48%.It was better to be use by sprayed the leaf at seedeing stage and turning green.
