焚烧，翻耕或清除秸秆从连续种植8种水稻作物的领域没有显着影响水稻产量，秸秆或粮食的N含量，肥料N的回收率或土壤有机质含量。当施氮量超过100公斤/公顷时，产量增加。秸秆和籽粒中的氮含量也随秸秆处理方式的不同而增加。施氮不影响土壤氮素和有机质含量。
Burning, plowing or removing straw from the fields with eight successively planted rice crops did not significantly affect rice yields, N content of the straw or grain, recovery of fertilizer N or organic matter content of the soil. Yields increased with N applications up to over 100 kg/ha. N contents of the straw and grain also increased irrespective of method of straw disposal. Nitrogen applications did not affect N or organic matter content of the soil.
