Polyhouse Farming Guide
Polyhouse farming is a widely recognized method of crops production under complete control environment condition.In polyhouse temperature,humidity,fertilizer,carbon die-oxide level,light etc are controlled with the automated system.In polyhouse a farmer could grow any vegetables and other crops in almost any given season in the year to control the environmental conditions.The polyhouse are provided more stable and suitable environment for the crops. This reasons the production of polyhouse is high compared to the production which are grown in open field areas. The polyhouse conserve the thermal radiation and also provides enough energy to help in photosynthesis.
The History of Polyhouse Farming
The idea of growing plants existed in environmentally controlled was since roman times.The roman king Tiberius caesar was advice to eat one cucumber daily.So a arrangements were made to grow cucumber during off season in movable beds using transparent stone.His country mens are then plan to have a confined structure where they can grow cucumber.The idea of closed glass house was one of the choices which worked well.During (16th and 17th) century glasshouses were constructed using glass lanterns,old panes in wooden frame etc.However the polyhouse farming technology fully established with the introduction of polythene after world war II.These structure use of polythene were know as polyhouse.first polythene use as polyhouse covered was made in 1948 at university of kentucky
Advantage of polyhouse Farming
- High production per unit are of land
- Easy control of pest and diseases
- Prolonged production period
- Efficient water utilization
- Low cost Labor
- High quality of crop production
- Timely crop production
- Saving on crop protection chemicals
- Less exposure to
Types of polyhouse
1) Naturally ventilated polyhouse.
2) Partial climate controlled polyhouse.
3) Fully controlled polyhouse
4)Plastic low tunnels
Low Cost Or Naturally Ventilatef Polyhouse
- Low initial investment.
- Constructed with locally available material such as bamboo ,timber etc.
- No specific control devices for regulating environmental parameters inside the polyhouse.
- Suitable during cold weather,especially in hilly areas
Based on the suitability and cost of construction, polyhouses can be further divided into three types.
- Low tech polyhouse
- Medium tech polyhouse
- Hitech polyhouse
Low tech polyhouse
The low tech polyhouse structure which is constructed using locally available materials.Bamboo,Timber,polythene sheets etc.this materials are uses to make low cost polyhouse.the protective ultra violet (u.v) films used as a cladding material.No specific control device are provided for temperature controlling or regulating environment parameters as in case of high tech polyhouse. But simple technique like increasing or decreasing humidity,temperature are adopted.Also light intensity can be reduced by putting nets or covering the sheets with jute fabric.
The low cost polyhouse is good for climatic zone where the temperature can be reduce in summer season by the removing the side wall.
Greenhouse users prefers to have manually or semiautomatic control arrangement owing to minimum investment. This type of greenhouse is constructed using galvanized iron (G.I) pipes. The canopy cover is attached with structure with the help of screws. Whole structure is firmly fixed with the ground to withstand the disturbance against wind. Exhaust fans with thermostat are provided to control the temperature. Evaporate cooling pads and misting arrangements are also made to maintain a favorable humidity inside the greenhouse. As these system are semi-automatic, hence, require a lot of attention and care, and it is very difficult and cumbersome to maintain uniform environment throughout the cropping period. These greenhouses are suitable for dry and composite climatic zones.
To overcome some of the difficulties in medium-tech greenhouse, a hi-tech greenhouse where the entire device, controlling the environment parameters, are supported to function automatically.
Components Of Polyhouse/Green House
Polyhouse or green house are constructed helps of ultra violet plastic sheet.Sheets are usually of 1501-micron thick plastic sheet.For this polythene sheet the temperature and humidity can easily be controlled in polyhouse as they prevent the thermal radiation from escaping which increase the temperature and energy .The temperature and energy help in the process of photosynthesis .After The polyhouse sheet need to be changed after around every 5 years.
Heating is usually required in winter season. Generally the solar energy is sufficient to maintain inner temperature of polyhouse but when this is insufficient, via media like construction of a tunnel below the earth of polyhouse, covering the northern wall of the house by jute clothing, covering whole of the polyhouse with jute cloth during night and installing solar heating systems can be considered.
In summer season when ambient temperature rises above 400C during daytime, the cooling of polyhouse is required. This is done by providing adequate ventilation and removing the internal air of polyhouse out of it in a natural manner or by installing high power fans which need to be switched on at regular intervals. Installation of
cooler on eastern or Western Wall can also be done to keep the temperature low and maintain proper humidity. Alternatively Water-misting mechanism can be installed.
Certain plants are damaged due to very high light intensity during summer. Shading reduces light intensity and cools the micro climate inside the greenhouse. Shade paints (lime or Redusol or Vari clear), agro-shade nets or retractable thermal screens are generally used and operated manually or through automatic devices.
