为了农作物的丰收,在“万元田”示范片内对病虫害实施综合治理,特别是纯经型的栽培模式(菜—菜—菜)尤为重要。随着季节的推移和农作物对气候适应性的不同,我们往往在同一时期,同一区域内种下多种同科作物。如春、夏季一般以葫芦科与豆科为主,而秋冬季是以茄科与十字花科为主。加之很多害虫具有迁飞与杂食性,病菌具有传染性。这样,很容易造成一种或多种病虫害对不同作物的交叉为害。根据这种情况,我们应采取防治措施。
In order to harvest the crops, it is particularly important to implement comprehensive management of pests and diseases in the “10,000 Yuan” demonstration tablet, especially the cultivation mode of pure type (vegetable-vegetable-vegetable). As the seasons change and the climatic adaptability of crops varies, we often plan to plant many kinds of crops in the same area in the same period. Such as spring and summer generally Cucurbitaceae and leguminosae, autumn and winter is based on Solanaceae and Cruciferae. In addition, many pests have migratory and omnivorous, the bacteria are contagious. In this way, it is easy to cause one or more pests to cross different crops. Based on this situation, we should take preventive measures.
