小麦是我省主要粮食作物之一,居夏粮第一位,但因我省系立体农业,地势气候复杂,单产很低,1978年亩产量最高仅178斤,远远落后于该年全国亩产236斤水平。低产的原因,主要是占小麦播种面积一半以上的旱地小麦,生长期中降雨量不足150毫米,一般无灌溉,再加上多利用春性品种,拔节,抽穗早,易遭寒害,致单产常不足百斤,拖了后腿。小麦夏秋种植能充分利用我省夏秋雨水、热量资源一般亩产200来斤,高的可达三至四百斤,因此,是近几年来我省农业科学研究的一项新成果,它在选种上,可以作到同年内加代选育,鉴定品种冬春性和抗锈 Wheat is one of the main grain crops in our province and ranks first in summer grain crops. However, due to the three-dimensional agriculture in our province, the terrain and climate are complex and the yield is very low. In 1978, the maximum output per mu was only 178 kg, lagging far behind that of the whole country 236 pounds level. The main reason for the low yield is dryland wheat, which accounts for more than half of the wheat sown area. Rainfall is less than 150 mm during the growing season. Irrigation is generally not used. In addition, spring wheat varieties are more commonly used. Insufficient, dragged the hind legs. Wheat summer and autumn planting can make full use of the summer and autumn rainwater in our province, calorific resources generally yield 200 pounds per catty, up to 3-400 catties, therefore, is a new achievement of agricultural science research in our province in recent years, On the species, can be done in the same year plus generation and selection, identification varieties winter spring and rust
