Effects of Different Straw Utilization on Farmland Moisture and Crop
, 2013 通过小区试验,研究了粉碎、氨化秸秆以及与无机土壤改良剂(硫酸钙)混合配施措施对土壤水分及作物产量的影响。结果表明,氨化秸秆利于提高土壤对降水的保蓄能力,显著增加0~100 cm土层土壤蓄水量。在夏玉米-冬小麦轮作中,氨化秸秆提高土壤蓄水能力主要反映在夏玉米苗期和冬小麦抽穗期。粉碎秸秆氨化与硫酸钙处理的夏玉米、冬小麦水分利用效率分别较粉碎秸秆覆盖提高了4.97%、30.32%,效果显著。氨化秸秆施入土壤的措施较未氨化秸秆覆盖还田的措施夏玉米、冬小麦产量分别提高4.56%~10.00%和6.65%~11 ...
