短期和长期中水灌溉对绿地土壤理化性质的影响
Effect on Greenland Soil Physical and Chemical Properties Irrigated by Reclaimed Water for Short-term and Long-term
摘要
Abstract
Adopt short-term indoor reclaimed water irrigation in the soil column simulation and long-term field investigation,identify positioning,for reclaimed water irrigation to plant nutrients mischief ion and heavy metal element,and decrease of change were compared and analyzed.Results showed that,with clear-water contrast,reclaimed water irrigation made greenland soil pH lower,soil organic matter content increased,porosity increased,density and field capacity decreased;Total nitrogens,total phosphorus content with the soil layer increases had decreasing trend;Alkali-hydro nitrogens,phosphorus and rapidly-available potassium content effectively controlled between water and increase and remarkable difference（P0.05）;Salt ions in the soil to accumulate,content increased;Toxicity ions and heavy metals content were increasing or decreasing trends,and were concerned with different ion species,but its content was few,the accumulation effect changed slowly,and because of natural precipitation factors such as soil microorganism dilution and plants,factors such as the absorption and tutorials,general won＇t cause damage to the soil pollution and stress on plant growth.关键词
