Blotting paper is equipped between plant leaf specimen and plant leaf specimen (according to aqueous how many determining suctions of plant leaf specimen
The number of plies of water paper), water suction paper size should be identical as clamping plate, pays attention to that arrangement keeps plant leaf specimen smooth, for be not easy to press dry
Succulent plant sample is first scalded with boiled water after death re-compacted.Two clamping plates are clipped with specimen holder, are bound with rope, ventilation is placed in
Locate drying, and in changing paper 2-3 times in 1 day, should be noted that when changing paper not make plant leaf specimen fold.
The vacuum pack with nitrogen of step 2, plant leaf specimen
Using small food vacuum nitrogen filling packing machine, to step 1, treated that the vacuum packaging of plant leaf specimen is housed
Bag carries out vacuum pack with nitrogen.The air in vacuum packaging bag is extracted, condition is vacuum-packed：Pumping can not make vacuum packaging bag
Interior absolute anaerobic, it is desirable that the percent by volume of the oxygen in vacuum packaging bag is 1% hereinafter, being suppressed microorganism and worm's ovum
And stop breeding, if micro- life of the percent by volume of the oxygen in vacuum packaging bag on 1.5% or more, plant leaf specimen
Object is the same as growth and breeding in air；The inert nitrogen gas being filled in vacuum packaging bag is able to maintain plant leaf specimen original
Some appearances will not be such that plant leaf specimen deforms, and bag face is wrinkle resistant.The nitrogen pressure of small food vacuum nitrogen filling packing machine is set
0.3~0.5MPa of power, 25~50s of air extraction time, nitrogen 2~5s of inflationtime heat the temperature and time of sealing according to packet
Depending on pack thickness, it is desirable that sealing is air tight, heats 8~15mm of seal widths.It is required that in packaging bag after vacuum pack with nitrogen
Oxygen is 1% hereinafter, 0.01~0.05Mpa of pressure.Vacuum packaging bag has moisture-proof, oxygen barrier, antistatic, vacuum-pumping spy
Property, thickness is had to, and to be suitable for that vacuum packaging bag is too thin be easily damaged when heating sealing, and pack does not have vacuum-packed anti-
Protect effect；It is too thick to be easy to happen cracking, gas leakage, influence the storage life of plant leaf specimen.
Embodiment 2：
