通县50余万亩小麦自1984年起打破十年徘徊,亩产达到256公斤.以后稳步增产,到1988年亩产突破300公斤大关,达到313.3公斤.1989年亩产362公斤,初步跨入高产行列.为了给小麦生产再上新台阶作技术储备,我们吸取科研单位高产栽培研究的成果及外地经验,1989年在地力较高的梨园乡进行小麦亩产400公斤高产栽培模式的示范实践,现将全年的实践结果初报如下. More than 50 million mu of Tongxian County have been hovering for 10 years since 1984, reaching 256 kilograms per mu, and steadily increasing production afterwards. By 1988, the mu production exceeded 300 kilograms mark, reaching 313.3 kilograms. In 1989, 362 kilograms were produced per mu, In order to make wheat production to a new level for technical reserve, we draw on the research results of high-yielding cultivation research institutes and field experience in 1989, in the higher ground-pear Township wheat 400 kg per mu yield cultivation model demonstration practice Now the annual results of the initial report is as follows.
