润湿剂对栽培基质水分的影响
|
摘要
[目的]研究润湿剂对栽培基质中水分的保持作用,以期为润湿剂的进一步研究开发及大田应用提供参考。[方法]以草炭+河沙(V/V=1/1)为栽培基质,添加不同浓度(50、100、150、200、300 mL/m~3)的润湿剂,研究润湿剂对栽培基质吸水总量、水势以及水分蒸发总量的影响。[结果]在基质中添加润湿剂浓度为150 mL/m~3时效果最好。其中吸水总量为296.00 g,与对照相比增加了35.31%;基质水分蒸发总量最小值为162.42 g,与对照相比降低了18.52%;基质水势最高为-1.97 MPa,与对照相比增加了29.89%。[结论]润湿剂可以有效地增加基质吸水量,减少基质水分蒸发量,增加基质水势。
[Objective]To study the effect of wetting agent on water retention in cultural matrix,in order to provide more effective theoretical reference for further research and development of wetting agent and field application.[Method]The effects of different concentrations of wetting agents(50,100,150,200,300 mL/m~3) on the total water uptake, water potential and total water evaporation of peat and river sand(V/V=1/1)were studied. [Result]The effect was best when the wetting agent concentration was 150 mL/m~3.The total amount of water absorbed was 296.00 g, increased by 35.31% compared with the control.The minimum value of evaporation of matrix water was 162.42 g, which was 18.52% lower than the control.The maximum substrate water potential was-1.97 MPa, an increase of 29.89% compared with the control.[Conclusion]The wetting agent can effectively increase the water absorption of the matrix, reduce the evaporation of the matrix water and increase the water potential of the matrix.
