Commercial Floriculture

Growing structures

• Depending upon the area of cultivation, the growing structures can be modified to suit the local climatic conditions.
• In Commercial scale Anthurium cultivation can be taken up in
  • low cost polyhouses,
  • Shade houses or
  • Climate controlled green houses.

  

  LOW COST POLY HOUSES
• In areas where the relative humidity levels are low and the temperature levels are high, low cost poly houses are more suitable for commercial cultivation of Anthuriums.
• By creating a protected climate by cladding UV stabilized polythene, the relative humidity levels can be easily maintained and by providing top or side ventilation, the hot air can be easily expelled.
• Inside the poly house, the top portion can be provided with layers of two shade nets (50% and 25%).
• If the light intensity is very high a thin film of calcium chloride or lime can be sprayed on the external surface of the poly house to reduce the incoming radiation.

SHADE HOUSES
In many of the commercial Anthurium growing areas, shade houses are the most popular structures because of the simplicity of construction and low cost.
• The shade houses can be constructed by taking the support of existing tree trunks if the Anthuriums are grown in multistoried plantation cropping.
• In open areas wooden, granite or pillars can be erected at regular intervals connected by GI wires as a mesh on top.
• Shade net can be covered on the top to provide the required shade 75%, (ie., 50 +25%, shade nets).
• Provision can be made for installing overhead sprinkler/misters/fogging systems by running GI wires from one end to another end.

CLIMATE CONTROLLED GREEN HOUSES
The capital investment and the level of sophistication is more in climate controlled green houses than the previous two structures.
Climate controlled green houses can be adopted for growing Anthuriums in areas where conditions of growing are not so congenial or
To produce top quality blooms exclusively for export markets.
Unless it is warranted it is not advisable to go for such capital intensive structures.
