1965—1975年间,我们在循化撒拉族自治县清水公社下滩大队,与贫下中农相结合,开展春小麦高产稳产规律的研究。在毛主席的无产阶级革命路线指引下,革命促进了生产和科研的发展,该大队小麦平均亩产由1964年的419斤提高到1975年的1,032斤,其中良种起了很重要的作用。11年来品种更换了两次,品种每更换一次,产量出现一次折的突破。比较各种类型的品种在丰产田中的表现,可以比较清楚地认识高产对品种的性状要求,按照这些性状选育成新品种,用以进一步提高产量水平,这样就将丰产栽培和育种联结起来,达到高产再高产的目的。
During 1965-1975, we conducted research on the law of high and stable yield of spring wheat in the lower brigade of Shimizu commune of Xunhua Salar Autonomous County in combination with the poor and middle peasants. Under Chairman Mao’s proletarian revolutionary line, the revolution promoted the development of production and scientific research. The average yield of wheat in the brigade rose from 419 pounds in 1964 to 1,032 pounds in 1975, of which the good seeds played a very important role. In the past 11 years, the variety has been changed twice, and every time the variety is changed, a breakthrough in output has been made. Comparing the performance of various types of cultivars in high-yielding fields can clearly recognize the traits of high-yielding traits and breeding new ones according to these traits to further improve the yield level. In this way, high-yielding cultivation and breeding are combined to achieve High yield and then high yield purposes.
