我校生物系副教授孙昌璜同志早在五十年代就开始从事小麦高产栽培途径的理论与应用研究,曾于1959年提出了“在一定条件下,随着土壤肥力水平的提高,可以相应的提高播种量;当土壤肥力水平提高到一定程度以后,播种量则宜降低”的想法。1960年,他又提出了“在高肥条件下,群体内部光照不足是小麦高产的主要限制因子”,“适当降低播种量、加大行距,依靠分蘖是冬小麦高产栽培的发展方向”等新见解,并首次报导了“在高肥试验条件 As early as the 1950s, Comrade Sun Chang-huang, an associate professor of biology in our school, started to study the theory and application of high-yielding cultivation of wheat. He proposed in 1959 that under certain conditions, with the improvement of soil fertility, Amount; When the level of soil fertility increased to a certain extent, the seeding rate should be reduced “idea. In 1960, he also put forth new ideas such as ”under high fertility conditions, insufficient light within the population is the main limiting factor for high yield of wheat“ and ”appropriate reduction of seeding rate, increasing row spacing and relying on tillering is the development direction of winter wheat high yield cultivation“ , And for the first time reported ”on high-fat test conditions
