| 摘 要： | 稻田施用沼肥,结合少量化肥,水稻前期生长较慢,分蘖数和株高不如施用普通化肥或水稻专用肥,但后期转色好,且每穗实粒数、结实率、千粒重都优于施用普通化肥或水稻专用肥的处理,稻谷产量与施用普通化肥的处理相比无明显增产效果,比施用水稻专用肥的处理减产4.6%.但施用沼肥能大大降低生产成本,比施用普通化肥和水稻专用肥分别降低19.0%和42.5%,同时能提高土壤有机质和N、P、K等营养元素的含量,改善土壤结构.因此,稻田施用沼肥,不仅能降低生产成本,提高经济效益,还能改良土壤,提高土壤肥力,具有较大的推广价值. |

Application of biogas manure to rice |
|
| Abstract: | When paddy field was applied with biogas manure and a small amount of chemical fertilizer, the rice grew slowly at early stages, and the tillers and plant height were inferior to those with ordinary chemical fertilizer or special rice fertilizer. But at late stages, the colour turned smoothly, and the grain number per panicle,setting percentage and 1 000 grain weight were superior to those with ordinary chemical fertilizer or special rice fertilizer. The yield did not increase compared with the rice using ordinary chemical fertilizer and decreased by 4.6% compared with the rice using special rice fertilizer. Nevertheless, the production cost was reduced by 19.0% and 42.5% respectively when using biogas manure. Meanwhile soil organic matter and nutrient elements such as N, P, K were increased and soil structure improved. Therefore, applying biogas manure to paddy soil can not only reduce the production cost and increase the economic profit, but also improve soil fertility. This practice is well worth popularization. |
