野燕麦也叫燕麦草、黑燕麦等,其分布广,密度大,适应性强。繁殖率高,危害严重,影响禾谷类作物高产丰收,是一种恶性杂草。野燕麦属于一年生禾本科杂草。主要靠种子、土壤和肥料传播,其它如农机具、灌水、风力、鸟类等也能传播。其防除措施: 1.适当推迟小麦播期。播种前进行灌溉,诱发野燕麦萌发出苗,然后进行播前耕作消灭。2.轮作换茬。可采取小麦与油菜、马铃薯等双子叶作物轮作,经过2～3年的防除,基本上可消灭野燕麦。3.用燕麦畏播前处理土壤。每亩用40%燕麦畏乳油200克,对水15公斤,地面喷洒,或配制毒土25-40公斤,均匀喷施于地面,或用2.5～5公斤尿素作为载体。将药剂拌到尿素上撤施。施药后立即耕翻土
Wild oats, also known as oats grass, black oats, etc., its wide distribution, density, adaptability. Breeding rate is high, serious harm, affecting the harvest of cereal crops, is a kind of malignant weeds. Wild oats belong to the annual grass weeds. Mainly by the seeds, soil and fertilizer spread, other agricultural machinery, irrigation, wind, birds, etc. can also spread. The control measures: 1. Properly delayed the sowing date of wheat. Irrigation before sowing, induced germination of wild oat seedlings, and then sown before sowing. 2 rotation for stubble. May take wheat and rapeseed, potato and other dicot crop rotation, after 2 to 3 years of control, basically eliminate wild oats. 3. Treat the soil with oatmeal before sowing. 40 grams per acre with 200 grams of oatmeal EC, 15 kg of water, spray on the ground, or formulated 25-40 kg of poison soil, spray evenly on the ground, or 2.5 to 5 kg of urea as a carrier. Mix the agent to urea withdrawal. Plow soil immediately after spraying
