The study concerned about four cultivation modules(no mulch,straw mulch,plastic film mulch and furrow planting),three nitrogen fertilizer levels(0,120 and 240 kg N/hm2) and two wheat densities(seed rate of 180 and 225 kg/hm2).
59 kg/hm2,且主要积累在80-160 cm土层,土壤氮库不仅明显,且残留比前3年土壤剖面显著下移(前3年主要累积在100 cm),差异达显著和极显著水平;不同栽培模式和种植密度0-200 cm土层硝态氮残留累积规律及其小麦籽粒吸氮量基本相似,排序均为:地膜覆盖>常规种植>秸秆覆盖>垄沟种植;随施氮量的增加土壤硝态氮残留量也相应增加,N0处理0-200 cm土壤平均硝态氮残留量为57。
As a cultivation and irrigation method for field crops,wide ridge and furrow irrigation have already been paid attention gradually.
