Abstract

Several simple cooling methods have been shown to prevent excessive heating of soil in greet pot experiments. The methods recommended are (1) Maintaining the soil moist (pF2 was u this study); (2) Shielding the outside and bottom of the pots with aluminized insulation pap Watering the floor of the greenhouses during the hottest part of the day; and (4) Using shade where the experimental plants are not susceptible to etiolation under reduced light intensity effect of these relatively cheap methods on soil temperature are partially additive and therefore enhance the options.
