为了解决关中灌区小麦机械化播种和修筑畦埂之间的矛盾,我们初步试制成了作畦、松土、播种三用机。1976年秋在渭南县辛市、官道等公社9个大队20个生产队试播1,500亩,效果效好,受到群众欢迎。现介绍于后。一、设计思想关中灌区小麦、玉米一年两熟接茬紧,时间短,争时矛盾突出。一部分玉米茬小麦往往延误播期,造成粗种迟播的三类麦田,是妨碍小麦产量提高的一个重要
In order to solve the contradiction between mechanized sowing of wheat mechanized seeding and construction of shy reeds in Guanzhong Irrigation Area, we tentatively made trial production of three-purpose machines for shoveling, loosening and sowing. In the autumn of 1976, 20 production teams from nine brigades of communes and communes in Sinan, Weinan County piloted 1,500 mu of pilot projects with good results and were welcomed by the masses. Now introduced later. First, the design philosophy Guanzhong Irrigation Area wheat, corn cooked twice a year, followed by tight, a short time, the conflict prominent. A portion of corn stubble often delayed sowing, resulting in three types of late-sowing coarse-grained wheat fields, an obstacle to increasing wheat yield
