我国是一个人口大国,对于粮食生产的需求量也是非常大的,但由于建筑用地越来越多,用于农作物种植的土地逐渐减少,因此,提升土地的粮食产量至关重要。对于我国玉米种植来说,由于种植面积不断扩大,多种玉米病虫害的发病率也越来越高,严重影响了玉米的产量。那么如何防止玉米病虫害的危害,提高我国农作物的粮食产量,是我国农业部门面临的首要问题。
As China is a populous country, the demand for food production is also very large. However, as more and more land for construction is used, the land used for planting crops is gradually reduced. Therefore, it is of crucial importance to increase the grain output of the land. For China’s corn cultivation, due to the growing area of planting, the incidence of many kinds of corn pests and diseases are also getting higher and higher, seriously affecting the yield of corn. So how to prevent the harm of corn pests and diseases and improve the grain yield of our country’s crops are the primary problems our country’s agricultural sector faces.
