The potato pulp based multifunctional and biodegradable liquid mulching film is prepared by solution mixing method with Crosslinking carboxymethyl potato starch residue as the main raw material and plasticizer, reinforcing agent, wet strength agent and crosslinking agent as the modified additives and the field characteristics are studied. The results show that the liquid mulching film can improve the ground temperature 0.8~1.6 ℃, soil moisture content increased by 6.4%~17.9%, reduce the soil pH, decrease soil bulk density of 3.3%~26.9%, increase soil porosity of 4.2%~36.1%, and increase the soil fertility (nitrogen, phosphorus and potassium) by 5.1%to 15.3%. The degradation in weightlessness rate is reached as high as 67.8%after 60 d soil buried and the potato pulp based multifunctional and biodegradable liquid mulching film had good biodegradable properties.
