- 摘要:
- 为探讨深松耕作在半干旱地区气候条件下对玉米生长发育的影响,以玉米品种先玉335为试验材料,研究了春深松30 cm,秋深松30 cm垄作及常规表层旋耕15 cm耕作模式对耕层土壤水分状况、物理性状和玉米生长发育及产量的影响。结果表明:深松30 cm垄作有利于降低15~35 cm耕层土壤紧实度与容重,常规表层旋耕有利于降低0~15 cm耕层土壤紧实度与容重;深松垄作比常规表层旋耕有利于蓄积降水和降雨,秋深松30 cm处理蓄水效果好于春深松30 cm处理,秋深松30 cm、春深松30 cm垄作处理分别比表层旋耕15 cm处理增产11.15%和7.26%。
- Abstract:
- In order to discuss the effect of subsoiling tillage on maize growth of semiarid area,taking the maize variety Xianyu 335 as experimental material to study the effects of the ridge planting in spring subsoiling 30 cm,subsoiling 30 cm in autumn,and conventional surface tillage 15 cm topsoil on soil moisture conditions,physical properties and maize growth and yield.The results showed that the ridge planting subsoiling 30 cm was conductive to reduce soil density and soil bulk density of 15~35 cm topsoil,conventional surface tillage was conductive to reduce soil density and soil bulk density of 0~15 cm topsoil;the ridge planting subsoiling 30 cm were greater benefit for the accumulation of precipitation and rain than conventional surface tillage.The effect of subsoiling 30 cm in autumn was better than which in the spring subsoiling 30 cm.The yield of the ridge planting subsoiling 30 cm in autumn and in spring were higher than conventional surface tillage 15 cm by 11.15% and 7.26%.
