针对黑龙江省白浆土区干旱频繁发生、土壤风蚀严重的特点,采取原茬播种、打茬播种、旋耕播种及翻地处理四种耕作措施进行对比试验。结果表明,打茬处理的出苗率最高,达90%,其次为旋地处理,出苗率达到89%。不同耕作措施对土壤墒情的影响不同,保墒效果是原茬〉旋地〉打茬〉翻地。打茬处理的产量最高,比原茬处理增产15.4%,比翻地处理增产12.7%,比旋地处理增产2.1%。几个处理的经济效益率排序为打茬〉旋地〉原茬〉翻地。

For the features of frequent droughts and serious soil erosion in Heilongjiang Albic,take the conservation tillage of original crop,fight stubble,rotary tillage and plowing comparison to compare.The results show,emergence rate of fight stubble treatment is highest and up to 90%,the second emergence rate is the treatment of rotary tillage by 89%.Effects on soil moisture was different by tillage and consequent of maintain moisture was the original croprotary tillagefight stubbleplowing.The corn yield of fight stubble treatment was the highest and increased of 15.4% compared with the original crop handle,increased of 12.7% compared with fight stubble treatment and increased of 2.1% compared with the rotary tillage.The order of several deal with the economic rate was fight croprotary tillage original crop plowing.
