1983年我区秋播冬小麦461.39万亩。春季返青以后,陆续出现大面积死苗,一些地块甚至造成绝收。据拔节期考察,死苗麦田达355.1万亩,占播种面积的77%。纯死苗面积111.7万亩,占麦母面积的24.2%,比返青期增加81.6万亩。毁掉或毁种的42.4万亩,占麦田的9.2%,是七十年代以来死苗最重的一年。入春以后,我们多次进行考察,并召集有关技术人员座谈,对小麦死苗的原因做了初步分析。
In 1983, our district sowed 4,613,900 mu of winter wheat. After returning to spring, a large area of seedlings emerge one after another, and some of the plots even result in absolute failure. According to the study of jointing stage, the crop seedlings reached 3.555 million mu, accounting for 77% of the sown area. Pure dead Miao area of 111.7 hectares, accounting for 24.2% of the area of wheat mother, an increase of more than 816,000 mu of green. 42.4 million mu of destroyed or destroyed species, accounting for 9.2% of the cropland, is the heaviest year since the 1970s. After entering the spring, we conducted many visits, and convened a forum for technical staff to do a preliminary analysis of the causes of dead wheat seedlings.
