| 摘 要： | 在大田条件下，通过常规施肥和滴灌施肥处理，研究了其对苹果园土壤硝态氮年周期变化及不同土壤层次分布的影响。结果表明：常规施肥和滴灌施肥处理，0—20、20—40cm土层硝态氮分布在不同物候期的变化趋势一致，均呈双峰趋势，以新梢旺长期和果实膨大期为最高；60—80、80—100cm土层硝态氮分布在不同物候期的变化趋势也一致，均变化较为平缓；而40—60cm土层硝态氮分布在苹果不同物候期差异显著，滴灌处理明显高于常规处理。

| Abstract: | Under field conditions,the effects of conventional fertilization and fertigation on the annual cycle and distribution in different soil layers of soil nitrate in apple orchard were studied.The results showed that whether conventional fertilization or fertigation,the nitrate in 0~20 and 20~40 cm soil layers had the same bimodal trend in different phenophase,and its level was the highest in the new shoots growing and fruit expanding periods.The nitrate in 60~80 and 80~100 cm soil layers changed relatively smo... |
