摘要
通过供氧剂配方、用量及田间试验的研究,明确供氧剂对直播稻出苗率、秧苗素质和田间生长的影响。结果表明:供氧剂最佳配方为过氧化钙∶粘合剂∶填充物=16∶12∶72,用量为75%,出苗率达到90%以上,比不包衣提高12.2%,产量增加9.6%。
The influence of coating seed with oxygen-supplying agent on emergence rate, seedling quality, and growth and development in field of direct sowing rice were studied by means of oxygen-supplying agent formula, dosage and field experiment. The results showed that the favorable oxygen-supplying agent formula was calcium peroxide： bond： padding=16：12：72 and the ratio of oxygen-supplying agent was 75%. Through use of oxygen-supplying agent, the emergence rate was over 90%, 12.2% higher than uncoated control and the yield was raised by 9.6%, compared with uncoated control.
