摘要
在晚稻上进行秸秆腐熟还田试验,结果表明:秸秆腐熟还田可改善土壤理化性状,提高后茬作物N、P、K营养供应水平,极显著提高水稻产量;在试验条件下氮肥增产作用最明显。
A trial on effect of returning decomposed straws into paddy field on the growth of late rice was carried out. The results showed that straw returning improved soil physical and chemical character, enhanced the supplying level of N, P and K nutrition to succeeding crops and thus significantly increased the rice yield. Under the condition of this experiment, the yield increasing effect of N fertilizer was the most obvious.
