采用分期播种方法对赣饲一号纤毛鹅观草生长发育与温度的关系进行了研究。结果表明,影响该草发育进程的温度条件主要为均温及有效积温,且生育前期(营养生长阶段)以均温为主,随着生育期的推进、生殖生长的增强,有效积温逐渐成为主导因素;出苗至各生育期所需的生长天数及积温与成熟期产草量间存在着显著的相关关系,除分蘖期为显著负相关外,其它各生育期均为极显著正相关;各生育阶段生长天数对成熟期产草量影响的大小依次为分蘖至拔节、开花至成熟、拔节至孕穗、出苗至分蘖、抽穗至开花及孕穗至抽穗。
The relationship between the growth and development of Gancao No. 1 cilia and the temperature was studied by staged sowing method. The results showed that the temperature conditions affecting the developmental process of the grass were mainly average temperature and effective accumulated temperature, and the average temperature was mainly in the early growth period (vegetative growth stage). With the growth of the reproductive stage, the reproductive growth was enhanced and the effective accumulated temperature gradually became dominant There was a significant correlation between the number of growing days required for emergence to each growth period and the accumulated temperature and the amount of grass in maturity, except for the significant negative correlation at tillering stage. The effects of the number of days of growth stage on the yield of mature stage were in the order of tillering to jointing, flowering to maturity, jointing to booting, emergence to tillering, heading to flowering and booting to heading.
