1 低温冷藏库贮藏杂交稻种原理 1.1 温湿度对种子贮藏的敏感性及原理试验表明:一般农作物种子当库内温度为30℃相对湿度达85%时,酶蛋白开始变性,但在较低温湿度下其活性并不受破坏。禾谷类作物以杂交稻种而言,它的最大特点是既怕湿又怕热,当库内处于低温干燥种子含水量控制在12%以下时,虫霉生长繁殖受到抑制,种子中的酶处于吸附状态,呼吸强度减弱。低温冷藏库贮藏种子具有其显著的功效。利用低温低湿库即库内温度稳定在18～20℃。相对湿度65～68%的状态下能抑制种子的呼吸作用,延缓种子衰老,降低种子内贮藏物的消耗。还可抑制库内微生物及仓虫的生长发育,减轻为害。否则,
1 cold storage storage hybrid rice principle 1.1 temperature and humidity on the seed storage sensitivity and principle tests showed that: general crop seeds when the storehouse temperature is 30 ℃ relative humidity of 85%, the enzyme protein began to denature, but at lower temperature and humidity Under its activity is not damaged. For cereal crops, the most prominent feature of hybrid rice is that it is both afraid of dampness and heat. When the moisture content of the cold-dried seeds in the store is controlled below 12%, the growth and reproduction of the insects are inhibited. The enzyme in the seed is in Adsorption state, decreased respiratory intensity. Cryogenic cold storage of seeds has its significant effect. The use of low temperature and humidity reservoir that the library temperature stability at 18 ~ 20 ℃. The relative humidity of 65 ~ 68% of the state can inhibit the respiration of seeds, delaying the aging of seeds, reduce the consumption of seeds stored. Can also inhibit the growth of microorganisms and warehouse worms in the library to reduce damage. otherwise,
