豌豆因其所特有的根瘤固氮作用使其成为重要的养地作物,加之其生育期短,能适应多种气候及土壤环境条件,是重要的轮作倒茬和间套种作物。近年来随着人们保健意识的增强和农业结构的调整,豌豆的食用、深加工和畜牧业饲料方面的需求明显提高,已成为我国优势小宗杂粮作物和世界第二大食用豆科作物。白粉病作为影响豌豆生产的常见病害,在全国各地均有发生。随着全球气候变暖,白粉病对于豌豆的危害日趋严重,病害流行年份,产量损失可达50%,鲜荚和籽粒的数量和品质也明显下降,直接导致豌豆大面积减产,从数量和质量上严重制约了豌 Because of its unique nodule nitrogen fixation, pea has become an important upland crop, and its short growth period can adapt to a variety of climatic and soil environmental conditions. It is an important crop rotation cropping and interplanting crops. In recent years, with the enhancement of people’s awareness of health care and the adjustment of agricultural structure, the demand for peas for food, deep processing and animal husbandry feed has obviously increased and has become China’s small and coarse grain crops and the second largest edible leguminous crops in the world. Powdery mildew, as a common disease affecting pea production, occurs all over the country. With the global warming, powdery mildew is more and more harmful to peas. In the year of disease epidemic, the yield loss can reach 50%, the quantity and quality of fresh pods and grains also decrease obviously, which leads to the large-scale yield reduction of peas, from the quantity and quality Severely restricted the pea
