近年来,天津市每年种植冬小麦约200万亩,占粮食作物总面积三分之一左右。高产麦田约25万亩,中产麦田约95万亩,旱薄盐碱地麦田约80万亩。平均亩产近两年已突破200公斤。按冬小麦生态区划分,天津属北方冬麦区北部晚熟冬麦副区。尽管麦田面积不大,但土壤类型复杂,种植品种很多。近年来,生产上以丰抗号小麦为主栽品种,每年种植面积约占麦田总面积的55％。丰抗号小麦由于多年种植,加之良繁体系不健全,目前已
In recent years, about 200 million mu of winter wheat are planted in Tianjin each year, accounting for about one third of the total area of food crops. About 25 million mu of high-yielding wheat fields, about 95 million mu of middle-yielding wheat fields, about 800000 acres of wheat fields in drought-resistant saline-alkali lands. The average yield has exceeded 200 kg in recent two years. According to the division of winter wheat ecological zone, Tianjin belongs to the northern late winter wheat winter wheat sub-district. Although wheat fields are small in size, they have a complex soil type and a large variety of cultivars. In recent years, the production of Fung-resistant wheat-based varieties, annual planting area accounts for about 55% of the total area of wheat fields. Fung-resistant wheat due to many years of cultivation, combined with good propagation system is not perfect, is now
