我区位于里下河稻区东侧,常年种植水稻86万亩左右。自70年代后期大面积推广种植杂交稻以来,形成了一个以杂交籼稻为主体的中稻区。历年来,稻田草害是影响本区水稻大面积平衡高产的一个主要因素,全区每年因草害损失稻谷1.4万余吨。80年代以来,稻田除草一般都为单一措施,往往难以控制杂草的危害。为解决这一难题,我们总结了多年来防除稻田草害的成功经验,并结合我区生产实际,进行优化、组装,形成“以农业防除为基础,化
My area is located in the east side of the Lixiahe rice area, perennial planting about 860000 acres of rice. Since the widespread popularization of hybrid rice in the late 1970s, a medium-sized rice crop has been formed with indica hybrid indica as its main body. Over the years, paddy field grass damage is a major factor affecting the large-area, balanced and high-yield rice in the region. Each year, the region loses over 14,000 tons of paddy due to grass damage. Since the 1980s, paddy field weeding has generally been a single measure and it is often difficult to control weed hazards. In order to solve this problem, we summed up the successful experience in the prevention and control of paddy field weeds over the years and, in combination with the actual production in our region, conducted optimization and assembly to form a system based on agricultural prevention and control
