1.种子烘干的三大特点(1)为保证出芽率,种子自身温度不许超过43℃。(2)为保证不裂,对种子不许激热激冷。必须采取多层加热、缓苏,再加热、再缓苏的特殊烘干工艺,每段加热只脱除1～2个水,立即进入缓苏段以消除热、湿应力。使子粒内部微毛细管中的吸附水向外扩散均匀;子粒外层较高的温度向内传 1. The three major characteristics of seed drying (1) To ensure the rate of germination, the seed itself temperature should not exceed 43 ℃. (2) to ensure that no cracking, the seeds are not allowed to heat chilling. Must take multi-layer heating, slowing down, reheating, and then slow the special drying process, each heating only remove 1 to 2 water, immediately into the slowing of the Soviet Union to eliminate heat and wet stress. So that the particles inside the capillary micro-capillary water evenly spread out; higher outer temperature of the particle inward
