The Effect of Green Cover on Tree and Soil Physical Properties of Red Globe Vineyards
摘要
Abstract
Under the condition of high temperature in Summer, the effects of weed clearing and green cover with white clover on tree and soil physical properties of red globe vineyards were comparatively studied, in order to provid a theoretical basis for green grasses of the vineyard. The results showed that weeding green grasses of vineyards had an effect on chlorophyll,leaf area.in-ternode length and stem diameter,which increaseed 2. 33%,0. 55%,7. 69% and 6. 25%,respectively. However the effect was not significant. Under the high temperatures in Summer, weeding green grasses lowered the temperature significantly from the ground surface in the depth of 10 cm at 14:00-16:00,and the soil volumetric water content among the soil depth field in 0 - 10 cm was significantly higher than that at weed clearing place. Also,in the depth 30-40 cm range,field water capacity is slightly lower than that at the weed clearing area. Weeding grasses reduced the soil bulk density to 9. 49% and increased four percent of the total porosity;grasses also lowered the temperature of grape leaves and stomatal conductance. Clearly,vineyard orchard grass not only improved the micro-climate but also improved soil physical properties, and promoted root growth and absorption which were conducive to the growth and development of vines.关键词
