稻草还田腐熟可以改善土壤理化性状，对水稻生长的经济性状指标有一定的影响，稻草还田腐熟后提供的氮、磷、钾营养元素可以减施化肥用量。试验中与无稻草还田常规施肥相比，稻草还田腐熟，以氮磷肥用量减少10%，钾肥用量减少10%～20%为宜，可使当季土壤有机质含量增加0.1～0.2g/kg，提高0.3%～0.6%，而产量、产值和纯收益无明显差异。
稻草還田腐熟可以改善土壤理化性狀，對水稻生長的經濟性狀指標有一定的影響，稻草還田腐熟後提供的氮、燐、鉀營養元素可以減施化肥用量。試驗中與無稻草還田常規施肥相比，稻草還田腐熟，以氮燐肥用量減少10%，鉀肥用量減少10%～20%為宜，可使噹季土壤有機質含量增加0.1～0.2g/kg，提高0.3%～0.6%，而產量、產值和純收益無明顯差異。

Straw counters-field rotten can improve soil physical and chemical properties, the economic indicators of rice growth has certain influence, after the straw counters-field rotten provide nitrogen, phosphorus and potassium nutrient elements can reduce fertilizer use. The results showed that the experiment compared with no straw counters-field conventional fertilization, straw counters-field rotten, with 10% less dosage of nitrogen and phosphorus fertilizer, potash fertilizer consumption reduced by 10% ~ 20% advisable, can make the soil organic matter content in the quarter increased by 0.1~0.2 g/kg, increased by 0.3%~0.6%, and no difference between the yield and output value and the net benefits.
