The  Feature  of  the  Uniaxial   Bamboo

China  has  abundant  bamboo  resource ,among  which    are  sympodial  bamboos  grow  in  the tropical  areas ,  uniaxial  bamboos  grow  in  the  subtropical  areas , and  psychrotolerant amphipodial  bamboos  grow  in  areas of  high  latitude and  high elevation . According  to statistics , there  are  about  48 categories  of  bamboo  grow in  our  country , altogether  more  than  500  kind .  These  bamboos  distribute  in  territory  of  higher  than  latitude 40 degree  north . Because  of  the difference  in climate , soil , terrain  and  the distinctive inherent  feature  of  bamboos , the  distribute  of  bamboo have show obvious  features  of  zonality  and  regionality . In  the  following we  will  talk  something  about  those uniaxial  bamboos which  grow  in  the  subtropical  areas .

Uniaxial  bamboos  are  those  bamboos with  uniaxial  nature  ,and  they  have  real  caulines  underground . The  bamboo  poles  on  the  ground  are grow  in  a  sympodial  shape . Its  spore  can grow  into bamboo  pole , and  also  can grow  into  bamboo  stick . The  uniaxial  bamboos  usually  sprout  during  March  and  May ,    a  good  time  for  bamboo  to  enter  vegetation  period .  From  May  to June , after  the appear of  bamboo  leaves ,the  bamboo  sticks  come  to  its  grow  period .In August  and  September , bamboo  grows  the most fast. And  in  October , bamboo  enter  the  period  of  conceiving  bamboo  shoots . After  this , bamboo  gradually  stop  growing  .The  bamboo  pole  can  grow  to  a  height of 13 meters ,and  its  radius  can  grow  to  8  to  10 cm . The  colour  of  its  poles  is  usually  yellow ,  with some  irregular  green  lines  inset  on  it . The  bamboo  leaves  are  big,  appressed  and  droopy , and  its  appearance  is  noticeable , which make  it  a  valuable  category  for  seeing  and  enjoying. In  addition ,  bamboo  can  serve excellently  as objective  view ,can  be  built  into   bamboo  forest  for  tour ,and can  be  potted  for  admiring .What  is  more , bamboo  shoot  is  good  food  for  its  delicious  taste and  high  output , which  is  fond  by  many  people .

  All  in all  , uniaxial  bamboos are  quite  popular  among  people .

The Propagation of the pachymorph

     1.The propagation of mother bamboo that choose the mother bamboo which normally requires 1~2 year to complete its life cycle,growing robustly without disease and insect pest,with cadmium yellow bamboo rhizome  .Before digging the mother bamboo whose bamboo rhizome  is repete and bamboo stems comparably low and height diameter is not very thick, we should make sure the direction of bamboo rhizome;Then cut off the bamboo rhizome in the place of being  far from mother bamboo 30cm~80cm 。Gennerally , the  large size bamboo reserve  30cm~40cm of coming part of rhizome,and 50cm~60cm of removing  bullwhip.when digging,we should not shake the bamboo stems and cut off the upside with sharp knife ，and normally reserve 5~7 branch,then plant it into the planting hole which has been digged beforehand .T he depth in the dust is a little deeper about 3cm~5cm than originally. After planting ,we should irrigate it in time and cover it with grass ,then excavate  the drain and also setup the bracket to advoid shaking the root by wind and affecting the stable root.

2. The propagation of moving bamboo that choose the robust Rhizome under the ground which normally requires 2~4 years to complete its life cycle before it shoot emergence about one mouth.After digging up the bamboo rhizome,we should cut it into 60cm~100cm for a length with original soil as much as possible and protect the radical bud well ,then plant it into cave and lie the bamboo rhizome flat and cover it with soil to the height varied from 10cm to15cm and also cover with grass to prevent the moisture from transpiring.Generally as spring approaches,it may send forth tiny new bamboo.we should   trim 1/3 the  bamboo sheath and reserve 6~7  coils of branches to advoid new bamboo of  withering.

3.The propagation of   seeding     adopt ripe seeds ,and it is good for  sowing in that very year .Generally,the seeds of bamboo almost lose the whole  germinating ability after one year.
