B.Sc. (Ag.) IV Sem. (Production Technology for Ornamental Crops, MAP and Landscaping) Botanical Name : Dendrobium sp. Cymbidium sp.
Family : Orchidaceae Importance and Uses:
Important cut flower, more vase life
They exhibits wide range of diversity in form, size, colour, & texture of flower.
On plot it remain good for 1-3 months.
Good indoor plant, grown in garden, pots, basket etc.
Flowers are use in special functions Production technology of orchids Important genera:
1.Dendrobium 2. Cattleya,
3. Phalaenopsis 4. Cymbidium<br>
05
Soil:
Sandy loam soil with a pH of 5.5-6.5 is ideal.
Climate:
75% green shade net with 70 - 80% humidity, 18 - 28ºC temperature and light intensity of 1500-2000 foot candles is ideal for growing this tropical orchid. In high rainfall zones, the shade net house should be provided with a rain shelter. B.Sc. (Ag.) IV Sem. (Production Technology for Ornamental Crops, MAP and Landscaping) Types of orchid:
1. Sympodial type: Prostate rhizome whose growth terminates periodically with an upright pseudobulb, leaf & flowers eg Dendrobium, Cattleya, Cymbidium
2. Monopodial type: Form aerial roots from the stem as they are produced in their upward growth. Eg. Phalaenopsis<br>
06
Spacing and plant population:
The planting distance is 45 cm x 45 cm, allowing roughly 29,640 plants/ha.
Improved varieties:
Cymbidium sp.: Levis Duke Bella Vista, Margaret Thatcher, Kennywine, Golden girl Mini Beacon Red torch, Beauty Fred 6, Ames Bury, Baltic Glacier Mint ice, Angelica Advent, Dingwall Lenes, Peter Pan Greenleaves.
Dendrobium sp.: Sonia 17, Sonia 28, Emma White, Sakura Pink, Hieng Beauty, Renapa, Dorine White, Kasem White, Kasem Gold, PM-11, Waipahu Beauty, Sarifa Fatimah, Walter omae, Jiad Gold, Mme Vipar.
Propagation:
Propagation: Division of clumps, back bulbs and tissue culture plants. Planting Density of Orchids: 100,000-150,000plants/ha. B.Sc. (Ag.) IV Sem. (Production Technology for Ornamental Crops, MAP and Landscaping)<br>
07
Manures and fertilizers
Foliar application of N:P:K as 30:10:10 @ 0.05% on the plant and potting
materials at an interval of 15 days during 1st year (young plants stage). For intermediate growth stage (2nd year ) foliar apply 20:20:20 of NPK @ 0.05% at an interval of 15 days. At late growth stages (3rd year on word) apply N, P, K as 15:25:25@ 0.1% at an interval of 15 days.
Irrigation
Mist or overhead sprinkler to provide water and to maintain humidity.
Weed Management:
Weeds in the orchid pots can be easily managed manually by picking through hand and single tooth fork. B.Sc. (Ag.) IV Sem. (Production Technology for Ornamental Crops, MAP and Landscaping) Containers and support : perforated earthen pots are ideal and the plants are staked with bamboo sticks.<br>
08
B.Sc. (Ag.) IV Sem. (Production Technology for Ornamental Crops, MAP and Landscaping) Plant Protection Measures:
Diseases:
Anthracnose: Foliar application of Thiophanate Methyl 2 g / l (or) Difenoconazole 0.5 ml/l.
Bacterial soft and Brown rot: Foliar application with Streptomycin Sulphate @ 0.5 g + Copper Oxy Chloride @ 2 g/l.
Black rot : Foliar application of Metalaxyl 2 g / lit. (or) Dimethomorph 50% WP 0.5 g / lit.
Orchids Botrytis: Foliar application of Mancozeb 2 g / lit.
Pests:
Scale insects and mealy bugs: Use a toothbrush dipped in isopropyl alcohol or a pesticide like Malathion, to physically remove the pest.
Red spider mites: Miticide like Kelthane applied on the undersides of the leaves.
Aphids: Sprayed with a pesticide like Malathion as per label instructions.
Snail and slug: Hand pick and destroy<br>
09
Harvest:
Dendrobium flower fully matures only 3 or 4 days after it opens. Harvesting the spike when 75 per cent of the flowers are open and remaining buds are unopen.
Yield:
8 - 10 spikes/plant/year B.Sc. (Ag.) IV Sem. (Production Technology for Ornamental Crops, MAP and Landscaping) Post Harvest Management:
Basal end of orchid spikes can be inserted in a tube containing water or water with preservatives of 2% sucrose or 2% sucrose+100 ppm Ca(NO3), or 2% sucrose+200 ppm 8-HQS, or can be wrapped with wet cotton swab, then they could covered with plastic and tied with rubber band to keep it in place.
Tropical orchids are stored at 7-10°C and temperate orchids are stored at 5°C. To prevent moisture loss and wilting of the cut flower 90-95% relative humidity should be maintained in the store.<br>
