推广秸秆还田技术不仅仅是减少秸秆焚烧的重要措施,而且是农业可持续发展的战略抉择。2009年,在广西大化县都阳镇都阳村拉万屯进行了早稻秸秆还田不同用量比较效果试验,旨在于研究水稻秸秆还田对产量的影响。试验结果表明,水稻秸秆还田不同用量对水稻产量有着明显差异,经方差分析,还田稻草600 kg/667m2时,达到差异极显著水平,还田稻草400 kg/667m2,达到差异显著水平。
The promotion of straw to field technology is not only an important measure to reduce straw burning, but also a strategic choice for sustainable agricultural development. In 2009, we conducted a comparative experiment on the effect of different amount of straw returning from early rice to paddy field in Duwantun, Duyang County, Duhua County, Guangxi. The aim was to study the effect of returning straw to rice field on yield. The results showed that there was a significant difference in the yield of paddy rice with different amount of rice straw returned to the paddy field. The variance analysis showed that the paddy straw reached 400 kg / 667m2 at 600 kg / 667m2, reaching a significant level of difference.
