Effect of Straw Mulching on the Soil Fertility and Tree Growth of Forest Land

Straw mulching can reduce the soil temperature,mitigate the storms’ direct erosion on the soil,reduce the loss of water,soil,and fertilizer,promote the accumulation,decomposition and transformation of soil organic and nutrients,thus it can rejuvenate the tree condition and raise the tree growth and nutrient content.the development of straw mulching,and the soil effect,environment effect and the effect on the tree vegetative growth produced by that were summarized in this article,and it provide the reference and basis for the exploration of the effect of straw mulching on the other non-wood forests.
