摘要
通过文献调研的方法,综合分析压砂地土壤物理、化学和生物学性质的演变特征。结果表明,压砂具有蓄水保墒作用,同时防止土壤水蚀、风蚀,减少水土流失。但随着压砂年限增加,压实作用造成土壤结构变差,土壤肥力和土壤关键酶活性呈降低趋势,土壤微生物结构发生变化,土壤连作障碍加剧,土壤质量总体呈下降趋势。从轮作休耕、节水高效栽培模式、深松深翻构建耕层、土壤快速培肥等方面,提出了退砂地土壤质量提升建议。
The method was adopted by literature survey,comprehensive analysis of the developmental characteristics of Soil physical,chemical and biological properties in gravel-mulched field.The results showed that soil water storage and moisture preservation was high with taking measure by gravel-mulch,at the same time,soil water erosion,wind erosion and soil erosion were decline.However,with the cultivation years increased by gravel-mulching,compaction resulted in soil structure worse,and soil fertility and key soil enzyme activities were decreased,soil microbial structure losing balance,soil continuous cropping obstacle was aggravated,and thus soil quality was totally declined.From four parts of crop rotation and fallow,water-saving and high efficient cultivation mode,subsoiling and tilling to construct plough layer,and soil quick fertility,proposing for improvement of soil quality after gravel removal.
