描述1.1. INTRODUCTION Plastic covering, either framed or floating, is now used worldwide to protect crops from unfavorable growing conditions, such as severe weather and insects and birds. Protected cultivation in the broad sense, including mulching, has been widely spread by the innovation of plastic films. Paper, straw, and glass were the main materials used before the era of plastics. Utilization of plastics in agriculture started in the developed countries and is now spreading to the developing countries. Early utilization of plastic was in cold regions, and plastic was mainly used for protection from the cold. Now plastic is used also for protection from wind, insects and diseases. The use of covering techniques started with a simple system such as mulching, then row covers and small tunnels were developed, and finally plastic houses. Floating mulch was an exception to this sequence: it was introduced rather recently, although it is a simple structure. New development of functional and inexpensive films triggered widespread use of floating mulch. Table 1.1. The use a/plastic mulch in the world (after Jouet, 2001).

Heat Balance of Bare Ground,. The surface also loses heat to the cold sky by long wave radiation. It can be visualized that heat is transferred by conduction to the lower soil layers, neglecting water movement in the soil. At the surface, not only sensible but also latent heat transfer occurs. These heat flows from the surface

Temperature Environment Under Cover, In the daytime, the main energy source is, of course, the sun, and its energy is stored in the soil. The transmissivity of the film used for covering is an important factor in getting a large amount of energy into the soil surface. At night, the energy source is thus the soil layer. The main heat l

CO2 Environment,ay the CO. level is fairly constant around 300 to 350 ./. due to photosynthesis by plants, and it rises to around 400 to 450 at night. The CO. level is more important under cover, especially in plastic houses where air exchange is normally restricted in order to raise temperatures in a cold climate.

Water and Water Vapor Environment,so water movement is related to heat flow. However, in order to simplify the problem and understand the system clearly, it is again assumed that vapor flow in soil is independent of heat flow, as we assumed in the chapter on heat flow analysis. Furthermore, we will focus only on vapor movement in th

Plant Response to the Environment,y under cover, is complex, and modelling it is not simple. This is one of the main reasons why most greenhouse models do not have or have only rather simple sub-models of plant growth. In the open field, the time courses of environmental conditions such as air temperature and carbon dioxide concentr
