一九七二年以来,我公社小麦平均单产连续四年达“纲要”,两年过“黄河”,并出现一批连年创高产的先进典型。但是,随着单位面积产量的提高,每亩投资水平也相应加大。如一九七七年,北瓦大队十队小麦单产539.3斤,每亩投资38元,每斤麦的成本超过了七分,增产不增收。如何解决这一问题?东马屯大队的经验做了回答。东马屯大队每亩投资也只39.55元但单产为1001.2斤,每斤麦的成本是三分九厘五。可见,实行科学种麦,充分发挥投资的经济效益,是夺取小麦高产量低成本的正确途径。现据先进典型的经验和我们几年来的调查 Since 1972, the average yield of wheat in our communes reached the “outline” for four years in a row. After two years of running “the Yellow River,” there have been a series of advanced models of continuous high-yielding. However, with the increase of output per unit area, the investment level per acre will also be correspondingly increased. For example, in 1977, the Northwestern Brigade’s 10-unit wheat yield reached 539.3 kg, with an investment of 38 yuan per mu. The cost per kilogram of wheat exceeded seven points, and the yield increase did not increase income. How to solve this problem? Dongma Tuntang team’s experience has been answered. East Ma Tun brigade investment is only 39.55 yuan per mu, but the yield of 1001.2 pounds, the cost per kilogram of wheat is nine-fifths. Therefore, implementing the scientific method of planting wheat and giving full play to the economic benefits of investment is the correct way to seize low-cost wheat with high yield. It is based on advanced and typical experience and our investigation over the past few years
