摘  要:
[目的]为了探索适用于中低产田改良的技术措施。[方法]采用不同农业废弃物资源,通过田间培肥的方式研究其对中低产水稻田土壤养分、作物产量的影响。[结果]与不施肥和单施化肥相比,化肥与秸秆、沼渣的配合施用对降低土壤容重,增加土壤有机质和速效磷含量的效果更加显著,化肥与秸秆处理还能明显增加土壤速效钾含量;在不同培肥方式中,化肥+沼渣处理作物产量最高;在秸秆还田措施中,与未添加腐熟剂的处理相比,添加腐熟剂能明显降低土壤容重,增加土壤有机质、有效磷、速效钾等养分含量。[结论]化肥与秸秆、沼渣的配合施用对中低产田土壤性质和肥力均有良好的改善作用。

摘  要:
[Objective] The research aimed to explore suitable improvement measures for middle-low yield field.[Method] An experiment was carried out to study the effects of agricultural residue on soil nutrient and crop yields.[Result]Compared with no fertilizer and chemical fertilizer,fertilizer with straw and biogas residue had a more significant effect on reducing soil bulk density and increasing soil organic matter and available P. The treatment of fertilizer and straw could increase available K obviously. Under different fertilization systems,crop yields of chemical fertilizer + biogas residue treatment was the highest. Under straw returning systems,compared with treatment without adding decomposition agent,adding decomposition agent could significantly reduce soil bulk density,and increase soil organic matter,available P and K.[Conclusion]Fertilizer with straw and biogas residue can significantly improve soil properties and fertility of middle-low yield field.
