增施猪粪有机肥以及不同比例替代化肥对冬小麦生长及土壤养分的影响

Effects of Increasing the Application of Organic Pig Manure and Replacing Chemical Fertilizers at Different Rates on the Growth and Soil Nutrients of Winter Wheat

猪粪有机肥作为一种有机资源,其养分含量丰富,施用后可培肥地力,提高作物产量,是实现农业资源循环可持续的途经之一。以冬小麦为研究对象,研究等氮量情况下有机肥替代化肥对冬小麦整个生育期农艺形状、品质及土壤养分含量变化的影响。研究结果表明:100%氮素有机肥+100%氮素化肥混合处理(T2)下的冬小麦产量与品质最高,产量较CK增加177.53%,粗蛋白含量较T1增加8.1%,粗脂肪含量最高较CK增加9.7%,T2处理下冬小麦湿面筋含量最高为为25.7%;施肥处理后土壤有机质含量主要表现为T2>T3>T4>T5>T1>CK;与单施化肥相比,有机+无机结合的方式更有利于增加土壤N、P、K元素的累积。

As an organic resource,pig manure organic fertilizer is rich in nutrients,and its application can fertilize the ground and improve crop yield,which is one of the ways to realize sustainable agricultural resource cycle.In this paper,the effect of replacing chemical fertilizer with organic fertilizer on the change of agronomic shape,quality and soil nutrient content of winter wheat throughout the fertility period was studied with winter wheat as the research object.The results showed that the yield and quality of winter wheat under 100% nitrogen organic fertilizer+100% nitrogen chemical fertilizer mixed treatment(T1)were the highest,with yield increasing 177.53% compared to CK,crude protein content increasing 8.1% compared to T2,crude fat content increasing 9.7% compared to CK,and wet gluten content of winter wheat under T1 treatment was the highest at 25.7%.Soil organic matter content after fertilization treatment was mainly T1>T3>T4>T5>T2>CK.Compared with chemical fertilizer alone,the combination of organic+inorganic is more beneficial to increase the accumulation of soil N、P and K elements.
