摘要： In order to select the best coating method, we compared the impact of three different mulching, black film, white film and non-coated, on soil temperature and humidity, porosity, and growth dynamics of shoot and root in the process of sweet potato's growth and development. The results showed that soil porosity was different between the coated and non-coated; coating can loosen the soil and play a role in soil moisture retention, and provide a good environment for the sweet potatoes. Compared to white film, the ground temperature under the coverage of black film can be controlled within the range more suitable for enlargement of sweet potato, and the growth of weed can be inhibited under the film. The yield of sweet potato covered by black film is the highest, the white film second, and no film minimum. This suggested that in the process of growth and development of sweet potato coating can improve the yield, and black film mulching technology is better than white film mulching technology. Collectively, the black film mulching technology should be vigorously promoted in potato cultivation.
