黑龙江风沙土区不同耕作措施对玉米地土壤水分及产量的影响
Effect of Different Tillage Patterns on Soil Moisture and Yield of Corn in Sandificational Area of Heilongjiang Province
摘要
Abstract
For the features of frequent droughts and serious soil erosion in sandificational area of Heilongjiang Province,the conservation tillage of fight stubble,rotary tillage and no-tillage were comparison with the local traditional tillage.The results showed that the soil moisture was improved significantly by rotary measure.Under the condition of rotary treatment,structure of soil was better and able to retain the precipitation effectively for increasing the capacity of water storage.The effects on soil moisture were mainly at prophase and medium-term of maize growth.In spring no-tillage treatment effectively kept the soil moisture because the times of farming were less than other treatments.The corn yield of rotary treatment was the highest and increased by 31.2% compared with the traditional one.The yield of fight stubble treatment was increased by 13% compared with the traditional one.The corn yield of no-tillage was the lowest and reduced by 20.4% compared with the control treatment.关键词
