采用长期定位试验 ,研究了砂质潮土一次性施入不同数量有机肥对数年小麦的产量效应、产量构成、品质、水分利用和土壤肥力的变化和影响 .结果表明 ,有机肥不仅能显著增加当季小麦产量、单位面积穗数和穗粒数 ,提高耕层土壤有机质、全氮、有效磷、有效钾含量和水分利用效率 ,而且有较长的后效 .小麦产量与有机肥用量的关系 ,随着时间的推移 ,由二次曲线回归效应转变为直线相关 ;小麦粗蛋白质、干湿面筋含量与有机肥用量呈显著正相关 The long-term experiment was conducted to study the effects of single-time application of different amounts of organic fertilizer on the yield, yield, quality, water use and soil fertility of wheat in the sandy soils. The results showed that the organic fertilizer not only significantly Increasing seasonal wheat yield, spikes per panicle and grains per spike increased soil organic matter, total nitrogen, available phosphorus, available potassium, and water use efficiency of topsoil, and had longer aftergrowth effects. The yield of wheat and organic manure Relationship, as time goes by quadratic curve regression effect into a linear correlation; wheat crude protein, dry and wet gluten content and organic fertilizer consumption was significantly correlated
