摘要:
[目的]比较不同有机物对新垦山地土壤的培肥效果,为开展新垦耕地后续培肥管护提供科学依据。[方法]在新垦山地红壤地,以3种不同有机物投入为因素,以空白为对照,在一年三熟蔬菜种植模式下,经连续3年小区试验,比较其对新垦耕地红壤肥力及蔬菜生长的影响。[结果]在3种有机物中,商品有机肥无论是在土壤培肥方面还是在蔬菜作物生产方面,均能体现出最佳效果。[结论]商品有机肥可作为新垦红壤地区施用的外源有机物之一予以推荐。而食用菌废渣的效果次之,可作为替代物品,水稻秸秆效果较差。

Abstract:
[Objective] To explore the effects of different organic matter on soil fertility of newly reclaimed land, in order to provide a scientific basis for subsequent fertilization management of newly reclaimed land. [Methods] Taking three different organic matters as the influencing factor and blank as the control, a 3-year continuous plot experiment was conducted, under a vegetable planting pattern of tree harvest a year, to investigate the effects of different organic matter on fertility and vegetable growth in newly reclaimed red soil. [Results] Among three kinds of organic matters, the treatment of commercial organic fertilizer showed the best effect on newly reclaimed red soil and vegetable growth. [Conclusion] The commercial organic fertilizer can be recommended as one of the foreign organic matter applied in newly reclaimed red soil region. The effect of edible fungus residue is the second, which can be used as an alternative product. The effect of rice straw is poor.
