利用玉米杂交种第一代的优势,是获得显着增产最经济而有效的办法。为了大力开展和扩大利用玉米杂交种来获得增产,1954—1955年我们在潞安增产示范县,重点的示范了华北春杂一号(金皇后×华农一号)和当地产生的潞杂一号(金皇后×土玉米)。根据两年来的经验,我们认为做好玉米品种间杂交种生产工作,应注意以下一些问题。1.杂交种示范和技术传授:为了迅速地开展和扩大利用玉米杂交种,与杂交种示范的同时,即应进行杂交种的种子繁育工作,因为在群众认识它的优越性以后,明年即可继续种
Taking advantage of the first generation of maize hybrids is the most economical and effective way to achieve significant yield increases. In order to vigorously carry out and expand the use of corn hybrids to increase production, 1954-1955 in Luan we increase demonstration counties, focusing on the demonstration of North China Spring One (Golden Queen × Huanong One) and locally produced Luza One (Golden Queen × earth corn). Based on the experience of the past two years, we think the following problems should be paid attention to in the production of hybrid varieties between different varieties of corn. 1. Hybrid demonstration and technology transfer: In order to quickly expand and expand the use of maize hybrids, and hybrid demonstration at the same time, that should be hybrid seed breeding work, because the masses recognize its superiority, the next year Continue to grow
