永安市稻草催腐还田试验初报

Preliminary Studies on Rice Straw Decomposition to Paddy Field at Yong’an City

2010年在永安晚季水稻上进行了早稻草加秸秆腐熟剂还田的试验。结果表明,在永安市气候条件下(7月中、下旬平均气温28～29.5℃),腐秆剂处理的稻草完全腐烂时间在18d左右,其稻谷产量与无稻草还田的常规施肥对照比较,增产率为4.13%～6.51%;"谷霖"微生物腐秆剂和"金葵子"腐秆剂适宜在永安市稻草还田上推广使用,建议每667m2稻草还田量300kg,施用腐秆剂2kg,尿素5kg或碳铵15kg为宜。

Early rice straws added decomposition agent to paddy field were studied on late rice of Yong’an City in Fujian in 2010. The results showed that, under the climatic conditions with the average temperature of 28.0-29.5℃ in the middle or late 10 days on July, the duration of complete decay straw by the treatment of straw decomposition agent was about 18d, its grain yield was 4.13%-6.51% higher than that of conventional application fertilizer without straw to field. Both＂ Gu Lin＂ microbial agent of straw decomposition and＂ Jin Kui Zi＂ straw decomposition agent were suitable for the extension and application of straw to field at Yong’an City, suggesting the amount of rice straw to field was 300kg/667m^2 by adding straw decomposition agent of 2 kg and urea of 5 kg or ammonium carbonate of 15 kg.
