【摘要】 本研究采用大田试验,分析了秸秆配方和废料配方两种土壤扩蓄增容肥对冬小麦生育期土壤有机质、主要速效养分和产量的影响。试验采用4因素(品种A、秸秆配方B、建筑垃圾配方C、灌水D)3水平正交试验设计。结果表明:施加土壤扩蓄增容肥可以有效提高土壤有机质含量达3.84g/kg;在节水条件下,能明显提高土壤速效养分的含量,增加了小麦对养分的吸收量,并优化了小麦对氮、磷、钾养分的吸收比例;并且施加土壤扩蓄增容肥较对照产量提高15%,且秸秆配方在各方面的效果均优于废料配方。更多还原

【Abstract】 A field experiment was carried out in order to assess the effect of two types soil magnistorage compatibilizer and diammonium incorporation on soil nutrients,bulk density and the yield of winter wheat.The orthogonal experimental design method was adopted and L934 table was chosen for the experiment:having four factors(A:variety,B:straw formulation,C:construction waste formulation,D:Irrigation amount) and three levels.The results showed that applying soil magnistorage compatibilizer could effectively improve the soil nutrients and the contents of soil organic matter,alkali-hydrolyzable nitrogen and available phosphorus increased by 3.84(g/kg)、42.63(mg/kg) and 27.00(mg/kg) respectively and decrease soil bulk density,and yield applying soil magnistorage compatibilizer was higher than that of CK by 15%.更多还原
