小麦是我省主要粮食作物之一。由于冬春气候温和,阳光充足,有利于农作物的生长发育,同时,也适于杂草的发生为害,与小麦争夺肥料、阳光、水分,影响小麦的生长及其产量的提高。麦田主要杂草有看麦娘、野燕麦、捧头草、繁缕、野豌豆、蓼、藜等。一般每平方尺有草一百株以上,如不及时防除,往往会使小麦减产一成左右。 Wheat is one of the main food crops in our province. As the winter and spring mild climate, sunshine, is conducive to crop growth and development, but also suitable for the occurrence of weeds, competing with wheat for fertilizers, sunlight, water, affecting the growth of wheat and its yield. The main wheat weeds have to see aunt, wild oats, head grass, chickweed, wild pea, Polygonum, quinoa and so on. In general, grass has more than one hundred grass-roots per square foot. If not eliminated in time, the yield of wheat will often decrease by about 10%.
