关中灌区的油菜,主要是歇茬地直播,还有少部分育苗移栽。东部灌区地多人少,肥力基础较差,采用歇茬直播的较多,一般产量较高。为了经济利用土地,不与粮田争地,我们在关中东部灌区,进行玉米茬直播油菜的试验,效果很好。1979年,渭南县辛市公社辛市大队三、四、九三个生产队,种植回茬直播油菜47亩,亩产分别为314、375和352斤。以后面积不断扩大,1981年辛市公社共300余亩,其中辛市九队30亩,亩产356斤;辛市七队种植30亩,亩产293斤。比歇茬油菜偏低,但按轮作周期计算,多种一料秋田,总收入较高。
Guanzhong irrigation rapeseed mainly live on the stubble, there are a small part of transplanting seedlings. Eastern irrigation less than many people, poor fertility base, using more stubble live broadcast, the general yield higher. In order to use the land economically and not compete with grain fields, we conducted a test of direct seeding rape with corn stubble in the eastern Guanzhong irrigated area, and the result was very good. In 1979, three, four and ninety-three production teams of the Xincheng Brigade, Xin City Commune, Weinan County, planted 47 acres of rapeseed live stubble, with 314,375 and 352 kilograms per mu respectively. After the area continues to expand in 1981, Xin City commune a total of more than 300 acres, of which nine groups of Xin City 30 acres, 356 kg per mu; Xin City, seven teams planted 30 acres, 293 kilograms per mu. Than intermittent rapeseed low, but according to the cycle for the calculation, a variety of materials Akita, a higher total income.
