关于小麦生产技术途径的研究,国内已有报导。山东农学院余松烈不仅研究了低产变高产的途径,而且提出了高产更高产的三条途径。北京市农林科学院作物所,通过对京郊大面积生产的总结也提出了小麦生产发展的四条途径。但是,这些研究的重点是在产量结构上,对栽培技术途径深入系统探讨不够。北京市农业局恽友兰等根据京郊小麦 Research on wheat production technology has been reported in China. Yu Songliang Shandong Agricultural College has not only studied the ways of low yield and high yield, but also put forward three high yield and high yield of three ways. Beijing Academy of Agriculture and Forestry Crops, through the summary of large-scale production in the suburbs of Beijing also proposed four ways of wheat production and development. However, the emphasis of these researches is not enough on systematic study of cultivation techniques in terms of yield structure.
