玉米是我省的一种主要作物,约占粮食作物面积的20％,其中春玉米占一半。绝大部分在秦巴山区。据1972年全省统计,单产为玉米平均亩产的70％左右。近年来,也出现了不少高产队。神木县呼家圪台大队74年27亩亩产1,660斤,秦岭山区的略阳九股公社庄科生产队30亩亩产916斤,渭北高原的合阳甘井公社北伍中四队旱地玉米,16亩亩产700斤,甘井五队178亩旱地玉米亩产620斤。因此,增产潜力很大。 (一)修建大寨田,加深耕作层:开展农田基本建设,改善农作物的生长条件,是增产的关键措施。宁强铁锁公社付家院子生产队10亩大寨地亩产612斤,而6亩普通坡地肥没少施,工未少化,亩产仅143

According to the statistics of the whole province in 1972, the yield per hectare is about 70% of the average mu yield of corn. In recent years, there have been many high-yielding teams. Shenmu County Hujiaotai Battalion 74 acres of mu 276 acres of 1,660 catties, Qinling Mountain Luguyou Jiuzhaigou commune Zhuang Division production team 30 acres per mu 916 pounds, the Weifang Plateau Heyang Ganjing commune North Wuzhong fourth team dryland corn , 16 mu mu yield 700 kg, Ganjing Wu team 178 mu dry land per mu 620 kg. Therefore, a great potential for increasing production. (1) Building Dazhai and deepening the tillage layer: Carrying out basic farmland construction and improving the conditions for the growth of crops are the key measures to increase production. Ningqiang Tieshugong commune pawn yard production team 10 acres of Dazhai yield 612 pounds per mu, and 6 acres of ordinary slope no less than fertilizer, labor is not reduced, only 143
