我市小麦生产自建国以来,经历了由满土到窄预留行到中厢分带轮作的发展过程。随之带来了我市玉米由夏播改为春播的变革,从而使我市旱地耕地粮食亩产由60年代的312公斤上升到80年代的750公斤,亩增产粮食438公斤,增产1.4倍。其中:玉米亩产由81.5公斤上升到275公斤,增产2.37倍。显而易见,推广旱地中厢分带轮作是提高旱地粮食亩产的重要技术措施。中厢分带轮作自70年代示范成功至今,已发展到100多万亩,占全市旱三熟种
Since its founding, wheat production in our city has undergone a development process from subsoil to narrower reservation to mid-car splitter rotation. As a result, the change of corn in our city from summer sowing to spring sowing resulted in an increase of grain output per mu in dry land from 750 kg in the 1960s to 750 kg in the 1980s, an increase of 438 kg of grain and an increase of 1.4 times in yield. Among them: per mu yield rose from 81.5 kg to 275 kg, an increase of 2.37 times. Obviously, the promotion of zonal rotation in the drylands is an important technical measure to increase the output of dry land grain. In the car sub-wheel rotation since the success of the demonstration in the 70s so far has developed to more than 100 million mu, accounting for the city drought three cooked
