小麦是我省仅次于水稻的主要粮食作物,分布很广,无论是盆地平丘河谷或是盆周山区,都有小麦栽培。随耕作制度的改革和高肥、密植、早栽等农田生态条件的变化,小麦病虫草鼠害问题日趋突出:种类增多、面积扩大、危害程度加重,成为夺取小麦持续高产的重要障碍,需要加强防治,研究新的防治对策。一、小麦病虫发生发展趋势我省麦类病虫种类很多,据记录有害虫124种,病害30种,杂草25种,害鼠15种,其中常发性并能造成较大经济损失的病害5种、虫害2种、杂草4种、害鼠5种,这是目前开展防治的主要对象。随着耕作栽培技术
Wheat is the second major grain crop in our province after rice, which is widely distributed. There are wheat cultivation in both the Pingqiu Valley and the basin-surrounding mountainous areas. With the reform of farming system and the changes of ecological conditions in high-fat, densely-planted and early-planted farmland, the problems of pest, weed and rodent pests in wheat have become increasingly prominent: the increase of species, the enlargement of the area and the aggravating of the harm have become important obstacles to the continued high yield of wheat and need to be strengthened Prevention, research new prevention and control measures. First, the development trend of wheat pests There are many wheat pests and diseases in our province, according to the records of 124 species of pests, diseases 30, weeds 25 species, 15 kinds of harmful rats, of which the frequent and can cause greater economic losses 5 kinds of diseases, 2 kinds of insect pests, 4 kinds of weeds and 5 kinds of harmful rats, which are the main targets of prevention and treatment. With farming cultivation techniques
