近几年来,河北省不少麦田中,都伴有“野生麦”的发生,一些地块由于连年恶性循环已泛滥成灾,成为小麦生产上一大公害。1996年藁城市农技中心对全市100多块麦田进行调查发现:田间杂株率一般在10％左右。严重的高达20％-30％,其中野生麦占田间杂株的90％以上,一般影响产量10％-15％,重的达30％-40％。野生麦的存在及发生发展,已成为高产麦区小麦产量再上新台阶的主要因素之一,因此下大力度彻底除治野生麦确保小麦增产丰收,是目前小麦生产上亟待解决的问题。
In recent years, many of the wheat fields in Hebei Province have been accompanied by the occurrence of “wild wheat.” Some plots have become a major public hazard in wheat production due to the successive years of vicious circle flooding. In 1996, Cheng City Agricultural Technology Center conducted a survey on over 100 wheat fields in the city and found that the rate of other plants in the field is generally about 10%. Serious as high as 20% -30%, of which wild wheat accounted for more than 90% of field crops, generally affect the yield of 10% -15%, weight of up to 30% -40%. The existence and development of wild wheat has become one of the major factors in the wheat yield in high-yielding wheat areas. Therefore, it is a pressing issue to be solved in wheat production to completely eradicate wild wheat and ensure the yield increase of wheat.
