近年连山区设施农业栽培面积逐年增加,全区温室大棚面积667 hm2左右。由于连年重茬,土壤环境恶化,土壤中病菌数量和种类增多,导致多种作物土传病害较重发生。常见的土传病害有枯萎病、黄萎病、青枯病、疫病、根腐病、猝倒病、立枯病、根结线虫病等。该类土传病害具有发生快、发病机制复杂,难
In recent years, the area of agricultural facilities in Lianshan Mountain has been increasing year by year, and the greenhouse area in the whole area is about 667 hm2. Due to perennial stubble, the soil environment deteriorated, the number and types of bacteria in the soil increased, resulting in a variety of crop-borne diseases occur more seriously.
