1979—1982年,我们在邗江县湾头公社田庄大队连续进行了百亩连片小麦高产栽培试验,同时于院内布置了必要的田间和实验室试验,初步摸索出一条改善小麦个体和群体生育的有效途径,这就是“小群体、壮个体、高积累”的高产栽培技术途径。采取这一途径,通过压缩群体起点,增加正馈效应时间和强度,为个体创造优越的生长条件,为群体进一步挖掘生产潜力。同时根据生育进程的“叶龄模式”,按时采用简易技术,促使个体与群体的生育动态合理,把穗群中分蘖穗的比例提高到60％以上,既满足了高产所需的适宜穗数,又使主茎和分蘖一并形成大穗、重穗;从而显著地改善了群体的质量,有效地提高了抽穗一成熟期,
In 1979-1982, we continuously carried out high-yielding cultivation trials of contiguous acres of wheat in Tianzhuang Brigade, Wan Tau commune, Qijiang County. In the meantime, the necessary field and laboratory tests were arranged in the hospital to tentatively explore a method to improve the fertility of individuals and groups of wheat Effective ways, which is “small groups, Zhuang individuals, high accumulation of” high-yield cultivation techniques. Taking this approach, we can create superior growth conditions for individuals and further tap the potential of production by reducing the starting point of the population, increasing the time and intensity of positive effects. At the same time, according to the “leaf age model” of the fertility process, simple techniques were used promptly to promote the dynamic growth of individuals and groups. The proportion of tillering panicles in the cluster was increased to over 60%, which not only satisfied the appropriate spikes for high yield, And the main stem and tiller together to form a large spike, heavy spike; thereby significantly improving the quality of the population, effectively raising a mature heading,
