Rain Protection Structure for Production of Vegetables

Introduction

Production of vegetables using buasa in the open high risk for the presence of pest and disease incidence,Now research suggests the cultivation technology of vegetables under structure protection (SPH) is a suitable and viable to produce vegetables Conditioning of medium quality land in the area of high and low.
                 Rain Protection Structure (SPH) for the purpose of cultivation of vegetables is to basically covered the installation of reinforced plastic structural framework made of either wood, steel, metal goods know it deems appropriate and affordable. The effectiveness of water protection is often enhanced by installing insect-proof nets as dinding.Pada SPH generally used for the production of vegetables is very high due to the high cost of building structures.

Types of Protection of Nature and Cost Structure Rain (SPH)

                  There are two types of SPH is commonly used in Malaysia, namely:
1. Saw the form of points2. Tunnel shape
Saw shape
Roof shape resembles a wooden saw blade assembly beruti and insect proof wall (made of plastic monofilm 600mesh) depending on financial ability.The cost for a structure, measuring 60 meters long and 10 meters wide and insect proof nets is within a range of RM 9.000.

Tunnel shape
Frame made of metal or flexible material which forms the tunnel finally appears.Materials often used was "galvanised iron." Bamboo can be used but its use was not long lifespan and easy to fall due to strong wind. The use of galvanised iron "requires long-term investment. Prices for the SPH-shaped tunnel, measuring 60 meters long and 10 meters wide is the range of RM25, 000, including insect-proof nets.
Benefits The use of SPH
1. Protection from heavy rains hit.      
Heavy rains cause physical damage and physiological of vegetables grown in the open. The use of SPH problems can be overcome. Hence, the production of vegetables will guarantee better quality and uniformity.

2. Strain reduction rays of the sun
    Temperate vegetables can not stand the rays of blazing sun and continuous. They require 20% - 30% shade for growth and optimum yields and quality.
3. Controlling diseases and insects
    Protection of water to provide effective use of insecticides and pesticides for control of disease around the moisture can be controlled. This will reduce the cost of the use of pesticides.
4. Weed Control
   Under SPH, excessive soil moisture due to rain can be avoided. This is due to the use of controlled irrigation system with moisture optimun only provide for the growth of vegetables cultivated alone. With this control problem weeds and to control costs can be reduced.
5. Pesticide residues Low
    With the use of pesticides are more effective, the content of residues in vegetables can be reduced. With this problem pesticides residues were also reduced.
6. Management and Effective Use of Manpower
   Labor can be used at any time without any reason. The work that is planned to be carried out despite the rain ruling. With this the cost of labor will be more efficient.
