1981年我部大面积推广应用氟乐灵除草剂,施用面积达135,000亩,占大豆总面积的90％。在长期低温、多雨、寡照及秋早霜的特大自然灾年情况下,多数连队虽然只蹚了蒙头土,或只进行了一次行间中耕,个别连队只趟了碰头土,后期人工重点拔了一次大草,不仅防止了豆地大面积草荒,而且保证了大豆的正常生育。在其它措施配合下,15万亩大豆秋后取得了平均亩产150斤的较好收成。其中六连4500亩,平均亩产270斤,十一连4250亩,平均亩产201斤。现将施药情况总结如下。
In 1981, our department extensively promoted the application of trifluralin herbicide, covering an area of 135,000 mu, accounting for 90% of the total soybean area. In the case of a natural disaster of long-term low temperature, rain, low light and early autumn frost, most of the company dived out of their own heads or only carried out intermediate cultivation. A big grass, not only to prevent a large area of grass wasteland, but also to ensure the normal birth of soybeans. In cooperation with other measures, 15 million mu of soybean in the autumn made an average yield of 150 pounds of better harvest. Six of them are 4,500 mu, with an average yield of 270 jin and eleven of 4250 mu, with an average yield of 201 jin. The application is summarized as follows.
