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的影响,以玉米品种先玉335为试验材料,研究了4种不同方式深松模式对耕层土壤水分状况、物理性状和玉米发育及产量的影响。结果表明:在苗期春季行间深松对蓄积降水效果不明显,可改善土壤物理性状,促进生长发育;夏季行间深松40cm与对照平作产量差异不显著,夏季深松效果好于春季深松,夏季深松40和30cm对产量影响不显著。
To discnss the effect of snbsoiling tillage on maize growth under the condition of semi-arid area,the maize cultivar Xianyu 335 was taken as experimental material to study the effect of subsoiling on soil moisture and physical properties and growth and yield of maize under 4 different subsoiling patters.The results showed that the collection water of the spring subsoiling between ridges in seedling stage was not obvious,but could improve physical properties of soil and growth of maize.The yield difference between subsoiling 40 cm in summer and flat planting（CK）was not significant.The effect of subsoiling in summer was better than which in the spring.The yield difference between subsoiling 40 cm in summer and subsoiling 30 cm in summer was not significant.
