春小麦是我省的主要粮食作物之一,常年播种面积1000万亩左右,约占全省小麦种植面积的一半。春小麦产量的高低影响着我省小麦单产的水平和我省粮食总产。我省各小麦产区地理环境及气候条件差别甚大,产量水平高低悬殊。从小麦生产水平的总体上看,中低产田所占比例远远大于高产田所占比例。因而,选育抗逆性强、适于中水肥条件下种植的春小
Spring wheat is one of the main grain crops in our province. The perennial planting area is about 10 million mu, accounting for about half of the province’s wheat acreage. The level of spring wheat production affects the level of wheat yield in our province and the province’s total grain output. The geographical environment and climatic conditions of various wheat producing areas in our province vary greatly, and the output level varies greatly. As a whole, the proportion of middle and low-yielding fields is far greater than the proportion of high-yielding fields. Therefore, breeding resistance is strong, suitable for planting under the spring fertilizer conditions
