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。
In this study, field experiments were conducted to analyze the effects of straw and waste formulations on soil organic matter, main available nutrients and yield during the growth period of winter wheat. The experiment adopted 4 factors (variety A, straw formula B, construction waste formula C, irrigation D) 3 level orthogonal experiment design. The results showed that soil organic matter content of 3.84g / kg could be effectively increased by application of soil extender and compatibilizer. Under water-saving conditions, the contents of soil available nutrients were significantly increased, the nutrient uptake by wheat was increased, Phosphorus, and potassium. The soil fertilization and fertilizer application increased soil fertility by 15% compared with the control, and the effect of straw formula in all aspects was better than that of the waste formula.
