摘要
在双季稻区进行早稻秸秆腐熟还田效果试验,结果表明:腐熟剂处理可缩短稻秆腐熟时间9 d,提早晚稻插秧5 d;与常规施肥(CK)相比,稻秆腐熟还田处理的土壤有机质含量提高8.2%,达显著水平,土壤肥力提升明显;晚稻增产12.1%,达极显著水平,且显著增加水稻有效穗与每穗实粒数。
Effect of returning decomposed early-rice straw into paddy field were studied in double-rice cropping area. The re- suits indicated that the decomposed period of rice straw treated with decomposing inoculants could be shortened by 5 - 10 d, and the seedlings of late rice could be transplanted 5 d earlier than before. Compared with traditional fertilization, soil organ- ic matter increased by 8.2% with the statistically significant level, soil fertility improved significantly ; the number of effec- tive ear and filled grain number per panicle were effectively increased, and rice yield increased by 12.1% with very signifi- cant level.
