摘　　要：在半干旱地区把振动深松和坐水种2种耕作技术应用到经济作物向日葵的种植中,在各个生育阶段采集土壤水分指标和光合指标,分析了不同耕作措施对土壤水分变化和光合速率的影响,以及各处理对产量的影响。试验结果表明,把振动深松和坐水种结合起来,有利于前期保苗和土壤水分的积累,效果明显,实际产量增幅明显;干旱少雨季节,在振动深松和坐水种基础上适当补水,可以大幅提高产量,避免减产。Using deeply vibrating-loosen culivation technology and sowing with water technology to plant the economical crop sunflower, the article tested the soil moisture index and the photosynthesis index during whole growth period, analyzed influence of the different tillage control measures to the soil moisture change, the photosynthesis rate, and also to the yield. The results indicate that combine using the deeply vibrating-loosen culivation and the sowing with water for sunflower seedling can ensure seedling and soil moisture accumulation, and the effect of yield increase for sunflower is also obviously. Based on deeply vibrating-loosen technology and sowing with water technology appropriately irrigate in dry season can considerably increase the yield of sunflower.
