Effects of Light and Heat Conditions on Yield in Experiment of Delayed Cool Injury in the Cotton Region of Kashi
摘要
Abstract
According to the study on cotton delayed cool injury in southern Xinjiang,this paper studied the effects of air temperature and sunshine duration on cotton yield in 2007-2008.The result showed that cotton yield increased with increasing accumulated temperature and duration of sunshine.The yield reduction resulted by the lack of the accumulated temperatures ≥20 ℃ and duration of sunshine in bud and boll opening periods was more than that in other growth birth,and more than that resulted by the insufficient accumulated temperatures≥10 ℃,≥15 ℃ and sunshine.Therefore,the annual accumulated temperatures ≥20 ℃could be taken as an important index in assessment of autumn delayed cool injury in autumn.关键词
