High temperatures and drought in summer significantly affect fruit yield, quality, appearance and storage life of kiwifruit. It is important to find a solution to overcome these problems. Using rice chaff as the covering material, we studied the effects of ground mulching on soil conditions and plant growth of kiwifruit in Changsha from 2006. The results showed that rice chaff had strong water-holding capacity, with saturated moisture content up to 1.4 times its own weight. Both chaff and chaff plus reflective film treatments substantially lowered the soil temperatures, and maintained them more constant. At the same time, chaff and chaff plus reflective film treatments reduced soil moisture loss effectively and increased soil available nutrient pools rapidly. Defoliation of kiwifruit plants was significantly reduced as a result.
