Effects of Different Mulching Methods on Ground Temperature in Soil Rubber Plantation

This paper analysis the di fferences among five mulching methods ((plastic film mulch, straw mulch, 1 cm biological material mulch, 2 cm biological material mulch, 3 cm biological material mulch) and bare land with three different depth (5 cm, 20 cm, 40 cm) in every season. The results showed that plastic film mulch and bare land’ s soil temperature are not significantly different with 5 cm in every season and 20 cm in spring and summer. Moreover, they are higher than straw mulch, 1 cm, 2 cm and 3 cm biological material mulch.There is no significantly differences between five mulching methods and bare land with 40 cm in spring and 20 cm, 40 cm in winter and autumn. There is no significantly differences between Plastic film mulch, 1 cm, 2 cm and 3 cm biological material mulch and bare land with 40 cm in summer. They are higher than straw mulch.
