豌豆是我省中部半干旱地区种植的主要豆科作物,在增加旱地农田生态系统氮素来源,培肥地力,轮作倒茬和提供人民植物蛋白以及发展农区畜牧业中都起着重要的作用。但近年来由于豌豆根腐病的大面积严重发生并迅速蔓延,致使产量大减,严重时绝收,其种植面积正逐年缩小,严重影响着旱地粮食产量的提高,而选育或选用抗病优良品种则是解决这一问题最为经济有效的途径。
Peas are the main leguminous crops planted in the semi-arid area in the central part of our province. They play an important role in increasing nitrogen sources, fertilizing fertility, crop rotation and rotation, providing vegetable protein and developing livestock husbandry in dry land. However, pea root rot in recent years because of the serious occurrence of a large area and the rapid spread, resulting in a substantial reduction in production, in case of serious harvest, the area is gradually reduced, seriously affecting the dry land to improve grain yield, and breeding or selection of disease-resistant Varieties are the most cost-effective way to solve this problem.
