摘要
研究不同秸秆腐熟剂对稻草还田的腐熟效果,结果表明:稻草还田添加秸秆腐熟剂可使稻草提早腐熟4~6d;水稻植株生长健壮,后期转色好;可促进水稻低节位分蘖,提高有效穗数、千粒重、结实率,增加水稻产量,提高经济效益;土壤有机质、全氮、有效磷、速效钾等养分含量均增加,尤其是速效钾含量增加明显;4种秸秆腐熟剂以"金葵子"对水稻秸秆腐熟效果较好。
Effect of different straw-decomposing inoculants on decomposing efficiency of the straw returned to paddy field was studied.The results showed that applying straw-decomposing inoculants could move up decomposition of treated straw by 4-6 dearlier;the rice plants grow strongly with good coloring at later stages,effectively promote tillering ability in the low-node position of rice,increase effective panicles,1000-grain weight,seed setting rate,rice yield and economic benefit,also increase the contents of organic matter,total nitrogen,available phosphorus,available potassium and other nutrients in soil,especially the content of available potassium was increased significantly.Among four kinds of straw-decomposing inoculants,＇Jinkuizi＇ has a better straw-decomposing efficiency.
