| 摘 要： | 以垦粳8号为材料,采用盆栽试验,研究不同膨化秸秆还田量对寒地水稻产量、品质及氮素利用的影响。结果表明,膨化秸秆还田量为360 g/盆的处理对产量、氮素利用效果最好,较秸秆不还田处理增产1.68%,提高氮肥农学利用率6.61%;膨化秸秆还田量为180 g/盆的处理在加工品质、营养品质和食味值等方面表现最佳。试验结果可为寒地水稻秸秆高效利用提供技术支撑。

| Abstract: | A pot experiment was used to study the effects of different amounts of extruded straw returning to the field on the yield, quality and nitrogen utilization of rice Kengeng 8 in cold regions. The results showed that the treatment with the extruded straw returning to the field with 360 g/pot had the best effect on yield and nitrogen utilization. Compared with the treatment without straw returning, the grain yield was increased by 1.68%, and the nitrogen fertilizer agronomic utilization rate was increased by 6.61%. The treatment with the extruded straw returning to the field with 180 g/pot performed best in terms of processing quality, nutritional quality and taste value. The results can provide technical support and theoretical basis for the efficient use of rice straw in cold regions. |
