沼肥对水稻产量的影响

The Effect of Biogas Fertilizer on Rice Yield

[目的]有效解决沼渣、沼液的使用,是现代循环农业的迫切需求。就沼渣、沼液作为肥源代替化学肥料对水稻生长与稻谷产量影响作了初步探讨。[方法]施用不同量的沼肥或沼肥与化肥混合肥作为基肥,测定生物学性状和产量性状。[结果]沼肥施用量的多少对水稻的穗长影响较弱,混合施肥的产量均高于单施沼肥的产量。[结论]在水稻生产中,株高及产量因素主要受肥料中大量元素影响,肥力越高水稻产量越高。单施沼肥,其大量元素含量不满足水稻的高产需求,降低水稻的产量。

[Objective] Effective use of biogas residue is very important for modern circular agriculture. In this paper, we explored the effect of using biogas residue instead of chemical fertilizer on growth and yield of rice.[Method] Giving different amount of biogas fertilizer or mixed fertilizer（contained biogas fertilizer and chemical fertilizer）, then measured the plant biological traits and yield traits. [Result] Quantity of biogas fertilizer did little effect on plant. Yield of mixed fertilizer was higher than biogas fertilizer. [Conclusion] Macroelements plays a main role in plant height and yield. Higher fertility lead larger yield. If only use biogas fertilizer, the rice yield was reduced.
