| 摘 要： | 秸秆覆盖降低了土壤温度,缓和了暴风雨对土壤的直接侵蚀,减少了水、土、肥的流失;促进了土壤有机质和营养物质的积累、分解和转化,从而复壮了树势,提高了树体的生长量及养分含量。本文通过综述秸秆覆盖的发展及其所产生的土壤效应、环境效应和对树体营养生长的影响,为探索秸秆覆盖对其它经济林的影响提供参考和依据。 |

| Abstract: | 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. |
| Keywords: | Straw mulching Soil effect Environment effect Tree growth Summarize |
