1 种子发热原因1.1 种子含水量高由于种子含水量高,新陈代谢旺盛,释放的大量热量积聚在种堆内,热量促使种温升高,呼吸作用加强,产生大量水汽,散发在种子堆内,进一步促进种子生理代谢活动,导致种堆放出更多的热量,循环反复会使种堆热量越积越多,种温升高,进一步导致种子发热。1.2 微生物和仓库害虫的迅速生长和繁殖引起种子发热特别是在20～35℃条件下,种子微生物居多,生长繁殖迅速,放出大量的热,易造成种子发热。1.3 种子堆放不合理种子堆过高过宽未留通道,易积聚热量且不易散发,引起种子发热。
1 reasons for seed fever 1.1 seeds with high water content due to high water content of seeds, metabolism, the release of a large number of calories accumulated in the reactor, the heat to promote seed temperature, respiratory effects, produce large amounts of water vapor, distributed in the seed pile, and further Promote the physiological metabolism of seeds, resulting in species piled up more heat, the cycle will repeatedly piled up more and more heat, seed temperature, further lead to seed fever. 1.2 microbial and warehouse pests rapid growth and reproduction caused by seed fever, especially in the 20 ~ 35 ℃ conditions, the majority of seed micro-organisms, rapid growth and reproduction, release a lot of heat, easy to cause the seed fever. 1.3 Seeds unreasonable stacking of seeds too high, too wide, no channel left, easy to accumulate heat and difficult to distribute, causing the seed fever.
