通过春性小麦分蘖成穗、小花结实、粒重潜力及其栽培效应的研究,探讨了春性小麦的超高产栽培途径。在保证一定成穗数的前提下,改善穗群组成,增加分蘖成穗,可显著增加每穗粒数和粒重,实现超高产。供试的五种栽培方案中,适期早播稀播利于扩大分蘖成穗范围,增加单株成穗数;利于个体生长充分,群体发展合理,且抗逆性增强。但相应的栽培技术尚需进一步研究。
Through spring wheat tillering into spikes, fruiting, gravimetric potential and its cultivation effect, to explore spring wheat super-high-yield cultivation methods. Under the premise of ensuring a certain number of spikes, improving the composition of the spike and increasing the number of tillers to spike can significantly increase the number of grains and grain weight per spike and achieve super high yield. Among the five cultivars tested, the sowing date of early sowing was suitable for expanding the range of tillering panicles and increasing the number of panicles per plant. It was good for individuals to grow well, the population developed reasonably, and the resistance was enhanced. However, the corresponding cultivation techniques still need further study.
