Vine species with climbing organs should also collect sheath whip or axe whip. 4.3 Process Firstly, the petiole is disconnected in the middle of the petiole, and the pinion and axillary whip (with axe vine species) of the distal end of the petiole and its shaft are collected; Sheath whip vine species), inflorescence or inflorescence base disconnected from leaf sheath, collecting sheath whip, inflorescence or inflorescence; finally the main stem is cut Non-endangered vine species), collecting leaf sheaths and canes. 4.4 Requirements 4.4.1 Petiole Petioles ≤ 30 cm in length should be collected intact. For petioles > 30cm, representative petiole segments must be collected. Petioles from 30 cm to 60 cm It should be collected at the base and top. Petioles > 60 cm are generally collected at the base, middle and top, and the length of each segment is ≤30 cm. 4.4.2 Feather Feathers should be collected together with leaf axis. Leaf blades with leaf axis length ≤ 30 cm should be collected intact, and leaves with leaf axis length > 30 cm should be selected Feather segments with representative morphological characteristics are generally collected at the base, middle, and top, and each segment is ≤30 cm in length. Collected feathers with a feather length of < 15cm can be retained. Only feathers with a feather length of> 30 cm should be retained on one side, and all other feathers on the other side should be retained. Cut off and keep only the base of the feathers, not exceeding 1 cm in length. 4.4.3 Axle Whip The shaft whip with a length of ≤100 cm should be collected completely and folded. Axial whip > 100 cm should be selected from representative morphological features. Generally, it should be collected at the base, middle and top. 4.4.4 Inflorescence Collect all well-developed inflorescences or parts that have typical classification characteristics. At the same time, collect some flowers and place them in paper or plastic bags. Add silica gel to dry. 4.4.5 Fruit order Collect all well-developed fruit sequences or parts that have typical classification characteristics. At the same time, collect some fruits and place them in paper or plastic bags. Dry into silica gel. 4.4.6 Sheath Whip The shaft whip with a length of ≤100 cm should be collected completely and folded. Axial whip > 100 cm should be selected from representative morphological features. Generally, it should be collected at the base, middle and top. 4.4.7 Leaf sheath The leaf sheath should be collected with a stipule sheath and a small petiole. The exposed part of the leaf sheath ≤ 30 cm should be collected completely; The leaf sheath of cm can only collect the part 30cm downward from the petiole connection, or the 15cm part of the upper and lower leaf sheaths as the center. 4.4.8 Cane Canes with obvious canes and not endangered should be collected with canes; canes should be collected with knots; vines with internode length ≤ 30 cm can be collected intact 1 internode with vines with an internode length of > 30 cm. Collect the upper and lower 15 cm sections centered on the node; the collected samples should be free of LY/T 2052. Defects specified. 4.5 Record See Appendix A. 4.6 Numbering The number of the collected plant material is the same as the same plant number, and each part should be marked with the corresponding number. The signing should include the collector, Basic information such as location, collection number and collection date.5 Processing5.1 suppression Lay the collected specimens one by one on several layers of absorbent paper, and then press the specimen clamps up and down to make them flat as soon as possible. Pay attention to the following situations when suppressing. -Try to make the cane, flowers, fruits, and feathers flat, and make the back of some feathers face up to observe the characteristics of the feathers; -Feathers with a feather length < 15cm can be folded from the base, and feathers with a feather length> 30 cm should be folded in the middle; -The thorny leaf sheath can be flattened first and then pressed; -The specimens should be placed with care to ensure that the specimens are balanced, and that the specimens are balanced evenly and not topple over. 5.2 Drying 5.2.1 Paper change drying method Press the absorbent paper to dry the specimen. Change the absorbent paper once every 1 d to 2 d, and change the paper 10 times. 5.2.2 Thermal drying method Dry in an oven or hot air blower. The drying temperature should not exceed 45 ° C, and the drying time should not exceed 48 h. 5.3 Disinfection 5.3.1 Cryopreservation Seal the dried specimen in a plastic bag and put it in a low-temperature refrigerator below -18 ° C for 7 d, or in a -30 ° C refrigerator for 3 d or a -50 ° C refrigerator 1 d. 5.3.2 Ultraviolet disinfection method Place under UV light for 1 h.6 Staple6.1 Materials and tools Specimen paper, scissors, utility knife, pencil, gel, gloves, needlework, etc. 6.2 Permutations 6.2.1 Integer The dried specimens were further trimmed and shaped to preserve the useful classification features of each part. If there are too many feathers, you can cut off some feathers Piece, but leave the base of the feather piece to show where the feather piece was cut. 6.2.2 Placement Specimen placement should follow the following principles. -Reserve labels and paper bags; -The specimen should be selected for the best side to show as many features as possible; -The feathers need to be displayed on 2 sides, and the flowers should be displayed on 2 sides as much as possible; --The specimens should be placed in the wrong direction from beginning to end. Large specimens should be placed diagonally. Excessively long specimens can also be folded into "V", "N" or "W" type placement. -When the same number of specimens cannot be placed on a single sheet of paper, the specimens can be placed on different sheets of paper separately, and each sheet should be marked with the same collection And the total number of sets of paper, and add A, B, C, D or -1, -2, -3, -4 to the collection number to indicate the difference. 6.3 Fixed The placed specimens should be fixed with sutures or adhesive banding. When using adhesive strapping to fix, use a pencil to select a few fixed points on the plant specimen Remember, use a utility knife to cut a gap of 0.5 cm to 1.0 cm in length, use a thin strip of paper to pass through the gap, and fix the back with glue. Fragments such as flowers, fruits, and leaves are packed in separate small paper bags and pasted in blank spaces. Lay flat on a dry place until the glue completely fixes the specimen. 6.4 Label Enter the content of the record into the computer and print it, and affix the printed specimen collection record label to the upper left corner of the paper, see B1 in Appendix B; The printed specimen identification label is affixed to the bottom right corner, see B2 in Appendix B.7 Save7.1 Packaging The prepared specimens should be packed in cardboard or placed in a specimen box, and the paper clip or box should be labelled. The label contains the Chinese name of the rattan and Latin Scientific name information. 7.2 Storage conditions Specimens should be stored in a specimen cabinet, which should be protected from sunlight and other light sources; the temperature of the place where the specimen cabinet is located should be controlled at 20 ℃ ~ 23 ℃, relative humidity is 40% ~ 55%.Appendix A(Informative appendix) Contents of palm vine plant specimen collection records I.
