《天津农业科技情报》1978年第一期上登载南郊区沿海大队写的“化学除草效果好”一文。我们认真地阅读后,认为他们在玉米、苗圃等方面的化学除草研究中,做了大量的持久的工作,取得可喜的成绩。但是在该文中提到“西玛津对玉米、小麦都有刺激作用”,“小麦比对照增产11.1％”。 “Agricultural Science and Technology Information of Tianjin,” 1978, the first issue of the submarine brigade in the southern suburbs of Shanghai written “chemical weeding effect is good,” a text. After reading them carefully, we think they have done a great deal of long-lasting work in chemical herbicides in maize, nursery and other fields and have achieved gratifying results. However, it is mentioned in the article that “simazine has a stimulating effect on corn and wheat” and “wheat yields 11.1% more than the control.”
