小麦-玉米轮作体系下长期定位秸秆还田对籽粒产量及品质的影响
Effects of Combined Application of Straw and Organic Fertilizer on Grain Yield and Quality under Wheat Maize Rotation System
摘要
Abstract
This study to Laiyang in Chao Soil Region long-term positioning straw of wheat-maize rotation as research object,applying nitrogen fertilizer were studied under the condition of straw returning and the single application organic fertilizer on wheat and maize yield and grain quality of influence.At the same level of nitrogen fertilizer,the two crop straw returning to field application of nitrogen fertilizer (WCN) treatment of wheat,corn grain crude fat content compared with a quarter of straw to field nitrogen fertilizer (WN) treatment significantly increased by 5.72％ and 9.49％.The proportion of straw was more conducive to improve the crude fat content of grain.WCN processing wheat,corn grain protein content than those of the other two season straw (WC) treatment significantly improved 32.53％,72.44％,showed that the proportion of nitrogen bigger was beneficial to improving the protein content.Single application of organic fertilizer and two season straw returning to field application of nitrogen fertilizer could significantly improve the yield of wheat and maize.Different straw returning treatment on wheat grain lysine,cystine acid,alanine had little effect,the corn grain cystine acid,glutamic acid,glycine has little effect,except for aspartic acid,leucine,valine,lysine lysine,cystine acid,alanine,long-term different straw also fields of other amino acids.To sum up,the application of nitrogen fertilizer on the basis of straw returning to the field can get higher yield and improve grain quality.关键词
