摘要 为研究豫南地区高肥力地块化肥减量对土壤肥力、粮食产量及经济效益的影响,试验选取稻-麦轮作种植制度,进行为期3年的定位减量施肥试验,在试验的小麦季和水稻季分别设置常规施肥、常规磷钾肥、常规施肥增氮肥5%、常规施肥减施氮肥5%和常规施肥减施氮肥10%5个处理。结果表明:随着处理时间的增长,常规施肥减施氮肥5%和10%的处理降低土壤容重,提高土壤有机质含量,而常规磷钾肥处理与之相反,试验处理均能提高土壤有效磷、速效钾和缓效钾含量。第一轮稻-麦轮作试验期间,常规施肥增施氮肥5%提高植株内全磷含量、小麦植株全钾含量及水稻的经济学性状;增、减施氮肥5%对植株内全氮含量、水稻全钾含量和小麦的经济学性状影响不明显。至第3轮试验期间,常规施肥增施氮肥5%与常规施肥的差异不显著;减施氮肥5%能提高小麦植株内全磷和全钾含量及作物产量,配合肥料支出少,获得的经济效益最高。 To study the effect of chemical fertilizer reduction on soil fertility, grain yield and economic benefit in high fertility land of southern Henan, the rice-wheat rotation planting system was selected and a three-year reduction fertilization experiment was carried out. There were five treatments: conventional fertilization,conventional phosphorus and potassium fertilizer, conventional fertilization with 5% nitrogen fertilizerincrease, conventional fertilization with 5% nitrogen fertilizer decrease, and conventional fertilization with 10%reduction of nitrogen fertilizer. The results showed that with the increase of treatment time, 5% and 10% ofnitrogen fertilizer reduction of conventional fertilization reduced soil bulk density and increased the content oforganic matter in soil. The treatment of conventional phosphorus and potassium fertilizer could improve thecontent of available phosphorus, available potassium and slow available potassium in soil. During the firstround of rice-wheat rotation, the total phosphorus content in plant, the total potassium content of wheat plantand the economic characters of rice increased under 5% nitrogen fertilizer increase, and the effects of 5%nitrogen fertilizer increase and decrease on the total nitrogen content in plant, the total potassium content of rice and the economic characters of the wheat were not obvious. To the third round of experiment, thedifference between 5% nitrogen fertilizer increase and conventional fertilization was not significant. Thereduction of nitrogen fertilizer by 5% could increase the total phosphorus and total potassium content and crop yield of wheat, and had the highest economic benefit with less expenditure on fertilizer.
