MULCH CAN REDUCE WATER LOSS FROM

PLANT.

THIS MAKE OUR PLANT TO SURVIVE LONGER

THEN WE EXPECTED.

USUALLY, MULCHIS USED AFTER WE

CULTIVATE THE PLANT FOR GIVE THE

PROTECTION FROM DIRECT SUNLIGHT.

MULCH MADE UP FROM LEAVES OR STEM

AND WILL BE PUT ON THE PLANT.

SHADOW FOR MINIMIZE THE

INTENSITY OF SUNLIGHT.

THE CHARACTERS OF SHADOW

PLANT IS THE TEXTURE THAT

FEATURES CROWN OF SOMERSET, HASBROAD LEAVES AND LONG BRANCHES

IN THE SHAPE OF AN UMBRELLA. THIS

TYPE OF SHADOW TREE IS NOT EASILY

BROKEN BY WIND.

Examples: Semarak Api (Delonix

regia),Tembusu (Fragea fragrans),

Bungor (Lagerstroemis speciosa) dan

Bunga Tanjung (Mimusop elengi)

Macronutrients

Divided into two groups :

- primary nutrients

- secondary nutrients

Primary nutrients

- use large amount for growth and survival.

- eg: Nitrogen(N), phosphorus(P),

potassium(K).

- Nitrogen:promote plants growth,important fornormal plant development.

- Phosphorus: important in stimulating root

development.

- Potassium: water regulation, resist drougt and diseases.

8/8/2019 pbl physio

20/20

Secondary nutrients

-use small amount.

-eg: calcium(Ca), magnesium(Mg), Sulphur(S)

-magnesium :important for crop quality,

support plant growth.

- Calcium: development of root system,shoot

tips and storage organ.

- Sulphur : ensure protein content is enough.
