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
SITE SELECTION: SOIL
● Physical, chemical and biological ● properties to be considered ● Soil texture (light sandy loam or loamy sand) ● Soil pH ● Soil fertility
26
SITE SELECTION: FREEDOM FROM WEEDS
● Free from annual and perennial weeds
27
SITE SELECTION: EXPOSURE AND ASPECT
● 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
SITE SELECTION: SLOPE
● 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
SITE SELECTION: WATER
● Quantity and quality considerations ● Water pH ● Water source
30
SITE SELECTION: SIZE OF THE AREA
● Wide enough to accommodate all essential parts of the nursery and supportive infrastructures
31
SITE SELECTION: GROUND COVER
● Least cost for site preparation activities ● Soil fertility and soil moisture regime
32
SITE SELECTION: SOURCE OF LABOR
● Labor intensive ● Close to source of abundant cheap labor ● Social desirability
33
SITE SELECTION: DESIGN AND LAYOUT
● 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
PARTS OF A FOREST NURSERY
PRODUCTION & NON-PRODUCTION
35
PRODUCTION AREA
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
NON-PRODUCTION AREA
non-direct but critical in the production of seedling stocks ● Nursery office ● Laborers’ quarters ● Motor pool ● Other infrastucture in support of seedling production
37
THE ROAD SYSTEM
● 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
WATER SUPPLY/IRRIGATION SYSTEMS
● From the source (impoundment system) 1. Gravity system 2. Pumps ● Distribution within the nursery 1. Open ditches 2. Surface pipes 3. Underground pipes
39
FOREST NURSERY PRODUCTION SYSTEMS
CONTAINERIZED PRODUCTION SYSTEM BAREROOT PRODUCTION SYSTEM
40
CONTAINERIZED PRODUCTION SYSTEM
● Potted ● Tube ● Sets ● Striplings ● Wildlings
41
BAREROOT PRODUCTION SYSTEMS
● Bareroot ● Stumps ● Balled planting stocks
42
ADVANTAGES OF BAREROOT
● minimal transplanting ● easier tending ● lesser weight during transport ● simple processing and handling of planting stocks ● best suited for mechanized planting
43
DISADVANTAGES OF BAREROOT
● 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
ADVANTAGES OF CONTAINERIZED
● 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
DISADVANTAGES OF CONTAINERIZED
● more expensive ● transport problems ● fewer planting stocks per trip ● greater risk of root binding ● needs continuous source of potting medium
