镇原县上肖公社六条路生产队是一个塬区生产队。粮食作物以种植冬小麦为主,常年播种面积360亩左右,占粮田面积的67.5％。1964年至1972年九年平均,冬小麦亩产只有166.7±66.3斤,波动幅度为39.5％。为了探讨旱塬粮作物的增产技术,1973年,原省农业科技工作队在上肖公社六条路生产队建立了综合试验组,研究和探索冬小麦的增产技术措施。通过多年的试验、示范和推广,冬小麦产量得到较大幅度的提高,1974至1982年九年平均亩产达到480.8±136.3斤,波动幅度为28.3％,与前九年平均相比,亩产增长188.4％,波动幅
Zhenyuan County Shangsha commune six production team is a highland production team. The main crops are winter wheat, with annual planting area of about 360mu, accounting for 67.5% of the total grain area. From 1964 to 1972, the average annual output of winter wheat was only 166.7 ± 66.3 kg, with a fluctuation of 39.5%. In order to explore the technology of increasing production of dryland highland grain crops, in 1973, the former provincial agricultural science and technology task force set up a comprehensive experimental group in the production team of Six Ways in Shangxia Commune to study and explore the technical measures for increasing winter wheat yield. Through years of experiments, demonstrations and popularization, the output of winter wheat has been greatly improved. From 1974 to 1982, the average yield per mu reached 480.8 ± 136.3 kg in the nine years from 1974 to 1982, with a fluctuation of 28.3%. Compared with the first nine years’ average, the yield per mu 188.4%, the fluctuation range
