Effect of vegetation on niche of mango anthracnose

The effect of vegetation on temporal 、spatial、nutritional niche of mango anthracnose was studied in this paper by niche theory.The result show: Average indexes of temporal niche breadth of mango anthracnose were 0.1763 and 0.2350 in the managing orchard and in herbiferous orchard,while Average Indexes of spatial niche breadth of mango anthracnose were 0.8557 and 0.9483.Indexes of nutritional niche breadth of mango anthracnose were 0.8741 and 0.7716 in the managing orchard and in herbiferous orchard.The results suggested weed could distend temporal and spatial niche breadth of mango anthracnose,but cut down the nutritional niche breadth of mango anthracnose because of weed offering more niche to mango anthracnose possibly.To mange weed reasonably may affect mango anthracnose and reduce degree of harm.
