龙岩市稻草还田适宜秸秆腐熟剂筛选与应用

摘要

Three straw decaying agents were used in field experiment to study their impacts on strawrot,soil nutrients and yield.The results showed that the agents could speed up straw decay five days in advance,but not significantly different among three agents.They all increase nutrient contents in soil,particular increasing organic matter content; and enhance rice yield 28.33,32.78,48.89 kg/666.7 m2,significantly to increase production,among them "hongshengyuan" straw decaying agents effect is best.%为了筛选出适宜武平县气候条件和耕作制度的秸秆腐熟剂,进行了稻草还田配施3种秸秆腐熟剂的试验探索.结果表明:(1)施用“谷霖”牌生物腐秆剂、“绿地康”有机物料腐熟剂、“鸿生源”秸秆腐熟剂处理秸秆还田,秸秆颜色、气味及软化程度均有较大幅度加快,秸秆腐熟提早5天以上且更完全,但3种腐熟剂品种之间差异不明显;(2)秸杆还田后,提高了土壤养分,特别是提高了土壤有机质,激活土壤缓效钾,培肥了地力.(3)水稻秸秆还田加施腐熟剂处理T78优2155各项主要农艺性状有明显改善,3种秸秆腐熟剂都显著增加水稻的产量,分别增产424.95、500.1、725.1 kg/hm2,“鸿生源”秸秆腐熟剂效果最好.
