  2. 2. BAMBOO • Known as “poor man’s lumber” • Considered as green gold all over the world by many bamboo enthusiast • There are about 1,200 species in the world • About 72 bamboo species are found in the Philippines • Known for its multiple uses
  3. 3. • Bamboo may be propagated by various methods: By seeds
  4. 4. Ooopppsss!!!
  5. 5. By rhizomes
  6. 6. By branches
  7. 7. Species that may be propagated using branches
  8. 8. Bamboo species that can be propagated by culm-cuttings
  9. 9. •select culms that are 1½ - 2 years old from a healthy bamboo clump •culm should have a shining pole and sheet on branches 1. Selection of planting materials BAMBOO PROPAGATION
  10. 10. How to select 1-2 years old culm:
  11. 11. Cut the selected culm above the first node from ground level using a hand saw remove the branches and foliages leaving at least 2 internode branches * Be sure not to damage their bud in the nodes
  12. 12. Cut the culms into 1 or 2 nodes cuttings using a sharp bolo or saw. The one node cutting consist of a node with a long open internodes and a portion of the branch to produce more planting stocks.
  13. 13. .... However, a 2-node planting stock has 2 nodes and one pole internode and an open internode in the end. It is more advantageous when frequent watering is not possible.
  14. 14. 2. Treat the cuttings with rooting hormone Dip/soak the cuttings in rooting solution in 5-10 minutes.
  15. 15. 3. Pot the cuttings cuttings should be potted immediately after being treat with rooting hormone Polyethylene bags - as potting materials *size of the bags may vary depending on the size of cuttings
  16. 16. 4.5 x 4.5 x 10 in. polyethylene bag - used for 10cm cuttings • The bags should have small holes on its lower portion in order to allow good drainage and aeration.
  17. 17. 3.1 Mix your potting media (coconut coir dust, garden soil, carbonized ricehull)
  18. 18. 3.2 Fill the lower third of the plastic bag with soil
  19. 19. 3.3 Mycorrhizal Inoculation (Hi-Q Vam 1) -Add 1teaspoon of mycorrhiza before putting the culm/branch cuttings in potting bags
  20. 20. Effects of Mycorrhizal Inoculation on Giant Bamboo after Five (5) Months: With Hi-Q VAM 1 Without Hi-Q VAM 1 above ground parts Beneficial Fungus:
  21. 21. More secondary/small roots With Hi-Q VAM 1 below ground parts Less secondary/bigger roots Without Hi-Q VAM 1
  22. 22. 3.4 Place the bamboo cuttings vertically in the center Then fill up the bag with soil
  23. 23. Water the newly potted cuttings filling the upper internode. Place the potted cuttings in a partially shaded area for one month.
  24. 24. During the first 20 days in the nursery, the potted cuttings must be watered regularly to maintain soil moisture and to ensure that the open internode is always filled with water. Gradually expose them to sunlight.
  25. 25. • After 6 weeks, all the rooted propagules with sprouts should be exposed to full sunlight in order to improve growth. This is the hardening phase.
  26. 26. •In 6-8mos. The rooted bamboo plants are ready for transplanting in the field.
  27. 27. Production cost for a single propagule *Cost of propagule using 1 node P3.30 Cost of plastic bag (4.5x4.5x10) 0.65 *Cost of soaking rooting hormone 0.20 Potting medium 1.15 Labor Cost of Potting 1.50 P 6.80 •A pole of bamboo for propagules = P50.00 each •A minimum of 15 propagules/pole = 3.30 each •A bottle of rooting hormone (P200) can soak 1,000 propagules, hence, 1 propagule costs P0.20 each
  28. 28. BAMBOOHAY!
  29. 29. Generally, commercial bamboo species in the Philippines thrive in a wide range of site characteristics although, it prefers well- drained And sandy loam soil at low medium altitude. PLANTATION ESTABLISHMENT
  30. 30. In preparing the plantation site the following steps are followed : 1. SKETCHING • sketch the main features of planting site such as accessibility, water sources and slopes • the sketch shows the exact location, size and form of the planting site.
  31. 31. 2. STAKING  Mark the 4 corners planting sites with long poles If the site is large, divide it into 100m by 100 m section. The recommended spacing for bamboo is 7m by 7m.
  32. 32.  For river bank stabilization, 5m by 5m planted in “kwengkang method”, as shown in the illustration is recommended.
  33. 33.  make the field layout of planting poles by establishing a pair of these lines that run along the boundaries plantation site and they are perpendicular to one another. 3. FIELD LAYOUT
  34. 34. clear the area from weeds and other unwanted trees or plants 4. CLEAR THE AREA FROM THE WEEDS 5. PREPARE THE PLANTING HOLES 60cm x 60cm - recommended size for the holes in marginal areas 40cm x 40cm -for well drained areas
  35. 35.  Place the topsoil on one side of the hole and subsoil on the other side to avoid confusion during planting  The topsoil should be used as bedsoil to the propagules. While subsoil should be spread around or used for terracing. Topsoil Subsoil
  36. 36. PLANTING Done on the onset of rainy season to allow the bamboo plants to develop the roots system before the start of dry season After 6 months in the nursery, the potted bamboo plants are brought to the planting site and placed beside the planting poles.
  37. 37. At planting time, the height of the potted plant can already be 50cm-1 m high. And have a well- developed root system.
  38. 38. Then, cut the plastic bag of the rooted plant and carefully remove it without disturbing the root system. Fill the bottom of the planting hole with 10cm layer of top soil and compact it slightly The top soil should have high matter organic content or enriched with organic material (ex.carabao dung or compost).
  39. 39. Place the bamboo plant vertically in the hole and fill it up with the topsoil. Gently compress the surface soil around the plant
  40. 40. And cover it with mulch, either with straw cut, grasses, or other organic materials
  41. 41. PROTECTION & MANAGEMENT The bamboo plantation should be well maintained especially during the first two years after planting Conduct ring weeding and strip brushing STEPS : - this reduces competition between weeds and bamboo plants.
  42. 42. .  Apply fertilizer to the planted propagules Cover them with mulch to reduce water loss from the soil and supply the plant with nutrients
  43. 43. Water the plants frequently during the days without rain or if they show signs of wilting. Replace dead plants immediately.
  44. 44. If the plantations is located in an area with long dry season, it is advisable to have a firebreak along the plantation Fire breaks are established by clearing 5m-10m strips of grasses and other inflammable materials. Construct fences if necessary.
  45. 45. HARVESTING At 5th year when harvested, better quality poles could be attained. Clump should be cut at 5 -10cm above ground just about the first node.
  46. 46. - harvesting operation should be executed - most of the nutrients of the bamboo are in the rhizome Start of rainy season or 2nd half of the dry season Bamboo that are used for construction materials, furniture and fish pens such as bayog, bolo, kawayan- kiling, kawayan-tinik and kayali should be harvested when it is 4 – 6 years old.
  47. 47. If bamboo will be used as banana props and for pulp making 3 year old bolo, laak, and kayali should be harvested. Commercial bamboo species are readily marketable as construction materials and raw material for furniture and handicraft industries.
  48. 48. Bamboo yards can be found in the provinces as market outlet. Bamboo pole can be bought at the plantation site. The estimated cost of developing a bamboo plantation is 55- 60,000/ha. This includes the nursery operation, plantation establishment, maintenance and protection.
  49. 49. Income can be derived up after 5-7 years at the 5th year, 5 poles can be harvested per clump. At 200 clumps per ha. 1,000 poles can be harvested in 1 ha. plantation. Prices of poles may vary on region depending on the bamboo species. In Luzon the average price is P80-P100/pole this would generate an income of 80,000- 100,000/ha.
  50. 50. Pole production is expected to increase as the plantation matures.
  51. 51. Choose desired end use Make sure market exists Long list of candidate species Short list of species Choose species with best growth and yield Subject each species to screening. Is species suitable to desired end use? Is species suitable to site to be planted? Are propagules easily obtainable? 1 2 3 Checklist
