Q

Why forest nurseries?

A
  • Irregular flowering and fruiting of most tree species
  • Planting stocks best for marginal areas
  • TLC during trees’ most delicate period of growth
  • Takes advantage of seed years
  • Seed and seedling selection possible

25
Q

SITE SELECTION: SOIL

A

● Physical, chemical and biological
● properties to be considered
● Soil texture (light sandy loam or loamy sand)
● Soil pH
● Soil fertility

26
Q

SITE SELECTION: FREEDOM FROM WEEDS

A

● Free from annual and perennial weeds

27
Q

SITE SELECTION: EXPOSURE AND ASPECT

A

● Open as possible
● Not exposed to strong winds
● East, northeastern facing slopes which are colder
● Consider orientation of nursery beds; nursery beds are to be parallel to the NE direction

28
Q

SITE SELECTION: SLOPE

A

● Flat areas not desirable; 3-5% slope is desirable so that rainwater will not stagnate, and distribution of water can be facilitated through gravity
● If too steep, do bench terracing

29
Q

SITE SELECTION: WATER

A

● Quantity and quality considerations
● Water pH
● Water source

30
Q

SITE SELECTION: SIZE OF THE AREA

A

● Wide enough to accommodate all essential parts of the nursery and supportive infrastructures

31
Q

SITE SELECTION: GROUND COVER

A

● Least cost for site preparation activities
● Soil fertility and soil moisture regime

32
Q

SITE SELECTION: SOURCE OF LABOR

A

● Labor intensive
● Close to source of abundant cheap labor
● Social desirability

33
Q

SITE SELECTION: DESIGN AND LAYOUT

A

● Should mimic a factory
● Requires a knowledge of the whole process of seedling production
● Takes into consideration all the activities and required facilities
● Should allow for economical movement of people and materials

34
Q

PARTS OF A FOREST NURSERY

A

PRODUCTION & NON-PRODUCTION

35
Q

PRODUCTION AREA

A

directly related to the nursery seedling culture

● Nursery beds
● Seed house
● Soil shed/storage
● Potting shed
● Compost compartment
● Seedling processing shed
● Tool room/chemical storage
● Water impoundment area

36
Q

NON-PRODUCTION AREA

A

non-direct but critical in the production of seedling stocks

● Nursery office
● Laborers’ quarters
● Motor pool
● Other infrastucture in support of seedling production

37
Q

THE ROAD SYSTEM

A

● Interior roads should be enough to permit turning space for vehicles
● Perimeter road for security reasons
● Surfacing with fine rocks or gravel
● Paths will also be necessary

38
Q

WATER SUPPLY/IRRIGATION SYSTEMS

A

● From the source (impoundment system)
1. Gravity system
2. Pumps

● Distribution within the nursery
1. Open ditches
2. Surface pipes
3. Underground pipes

39
Q

FOREST NURSERY PRODUCTION SYSTEMS

A

CONTAINERIZED PRODUCTION SYSTEM

BAREROOT PRODUCTION SYSTEM

40
Q

CONTAINERIZED PRODUCTION SYSTEM

A

● Potted
● Tube
● Sets
● Striplings
● Wildlings

41
Q

BAREROOT PRODUCTION SYSTEMS

A

● Bareroot
● Stumps
● Balled planting stocks

42
Q

ADVANTAGES OF BAREROOT

A

● minimal transplanting
● easier tending
● lesser weight during transport
● simple processing and handling of planting stocks
● best suited for mechanized planting

43
Q

DISADVANTAGES OF BAREROOT

A

● need for excellent nursery soil
● longer sowing synchronization time
● greater risk of root damage
● needs abundant water during nursery seedling culture
● non-flexibility of planting dates

44
Q

ADVANTAGES OF CONTAINERIZED

A

● no need for good nursery soil
● shorter production time
● root integrity preserved
● faster growth initiation after outplanting
● planting season can be extended
● minimal start-up time

45
Q

DISADVANTAGES OF CONTAINERIZED

A

● more expensive
● transport problems
● fewer planting stocks per trip
● greater risk of root binding
● needs continuous source of potting medium
