Abstract

To understand variations in soil moisture dynamics with afforestation of karst regions,simulation experiments in the intelligent climate-control chamber(RXZ) and in the fields were conducted in typical karst formations of the Huajiang Valley,the southwestern Guizhou Province. We used three types of much,including litter,stone and plastic film,with 0,30%,60% and 100% coverage,and conducted having seedlings(one-year-old pepper) and no seedlings. Results showed that soil moisture use was related to mulch type,mulch quantity,and whether having plants with continuous mulching best. To reduce mold due to moisture,plastic mulch excelled stone mulch with litter mulch being worse. However,results with afforestation showed that at least 60% mulch should be applied. The plant survival rate with stone mulching was higher than with litter which was much higher than plastic mulch. Even though plastic mulch had the lowest moisture for mold,plant survival rates with the plastic mulch were poor. So,in a typical karst valley area,afforestation under plastic mulching should be studied further.
