    摘要:

    葡萄施藥量應(yīng)隨葡萄冠層生長期變化而相應(yīng)變化,。采用3種施藥量調(diào)節(jié)模型,，以達到在葡萄上合理施藥的目的,。3種模型分別為Unit Canopy Row (UCR),、Leaf Wall Area (LWA)和DOSAVIA,。試驗結(jié)果表明,對于早期葡萄,，DOSAVIA和LWA兩個模型的沉積量和傳統(tǒng)的施藥量處理間沒有顯著性差異,；UCR,、DOSAVIA和LWA三模型之間也沒有顯著性差異,；在中期,，LWA模型和傳統(tǒng)的施藥量處理在沉積量上仍沒有顯著性差異，而UCR模型所取得的沉積量顯著小于其他3種處理,；在后期,，傳統(tǒng)的施藥量仍然取得了最大的沉降量。在所有的試驗中,，沉積分布（CV值）基本保持一致,。

    Abstract:

    The grapevine canopy changes a lot along the growth season, so do the application rates. Three models were used with the aim to apply pesticides on grapevine rationally. The models mentioned were unit canopy row (UCR), leaf wall area (LWA), and DOSAVIA. The results showed that at early growth stage, the deposits for DOSAVIA, LWA and traditional method were not different significantly, neither for UCR, DOSAVIA and LWA; at middle growth stage, LWA method achieved the similar deposits to traditional, UCR got the minimum deposits; at the late growth stage, the traditional method had the maximum deposits than the others. Among all the trials at three growth stages, the distributions of deposits （CV）were very closed to each other.
