燕麦灵和新燕灵都是防除野燕麦的化学除草剂。燕麦灵的施药期很短,只有在野燕麦二叶期使用才能获得最好的防除效果;到三叶期使用,药效就会降低。由于气候条件的影响和野燕麦出苗先后不齐,实际上难以做到适时用药,这是燕麦灵的一大缺陷。新燕灵的施药时间是在野燕麦三至六叶期,而且较迟用药防除效果更好。三叶期用药,作物产量较好,但由于防除效果差,野燕麦有再次蔓延的可能性;六叶期用药,防除效果好,可是由于用药前野燕麦的竞争作用会影响到作物的产量。为了弥补燕麦灵和新燕灵各自的短处,充分发挥其长处,国外研究者进行了二者混用的实验,得到比较理想的效果。
Oatmeal and Xin Yanling are all chemical herbicides that control wild oats. Oatmeal application period is very short, only in the second-leaf wild oats in order to get the best control effect; to the use of clover, the efficacy will be reduced. Due to the climatic conditions and the emergence of wild oats have been missing, in fact, it is difficult to achieve timely medication, which is a major flaw of oatmeal. The new Yan Ling pesticide application time is three to six leaves of wild oats, and later drug control better. However, due to the poor control effect, wild oats may spread again. Six-leaf treatment is effective in preventing and controlling the oats. However, the competition of oat before treatment will affect the crop yield. In order to make up for the respective weaknesses of Yanmai Ling and Xin Yanling and give full play to their strengths, foreign researchers conducted a mixed experiment and got the ideal result.
