春麦是宁夏主要粮食作物之一。解放前后灌区普遍栽培的地方品种:有(?)麦、毛(?)麦、山麦、白秃子、紅秃子及大青芒等。由于感染銹病、黑穗病和吸漿虫害較重,容易倒伏,产量低而不稳定,1952年后被良种碧玉麦所代替。碧玉麦一般此地方品种早熟、高度抗条銹病和黑穗病,吸漿虫害較轻,抗倒伏力較强,子粒大,产量高而稳定。但碧玉麦稈锈病較重,每穗粒数較少,亩产达550斤左右卽易发生倒伏,同时出現品种单一化的局面。因此根据本区情况,我们从1954年
Spring wheat is one of the main food crops in Ningxia. Before and after the liberation of irrigated areas generally cultivated local varieties: There? (?) Wheat, wool?? Wheat, wheat, white bald son, Red Baldy and Daqingmang and so on.

Jasper general This local varieties of early maturity, highly resistant to stripe rust and smut, sucking insects lighter, stronger lodging resistance, large grains, high yield and stability. However, jasper rust heavier wheat straw, grains per spike less, yield of about 550 pounds of 卽 prone to lodging, while the emergence of a single species situation. Therefore, according to the situation in this area, we from 1954
