为寻求新的,省工省力的耕作方法,我们自1976年开始对稻板田三麦机直播免耕法进行试验研究,1980年冬通过技术鉴定,1983年无锡市郊区机直播免耕麦面积已达2000多亩,占全区三麦面积的10%.其中出现了亩产600～700斤的生产队,800～900斤的田块,1982年2.15亩扬麦4号免耕机条播麦亩产高达912斤. In order to seek new, labor-saving and tillage farming methods, we started experimenting on the direct tillage and zero tillage method of rice field in 1976 and passed the technical appraisal in the winter of 1980. In 1983, Has reached 2,000 mu, accounting for 10% of the area of ​​three wheat.Among them there is the production team of 600 to 700 kg per mu, 800 to 900 kg of plots, in 1982 2.15 acres of Yang Mai No.4 tillage machine barley Yields up to 912 pounds per mu.
