- 摘要:
- 在樱桃生长旺期,利用Trime土壤水分速测系统测定的果园土壤水分,建立了土壤水分随深度的变化曲线,以及利用表层水分进行深层水分的预测模型.结果表明,0~90 cm范围内土壤水分变异幅度较大,0~90 cm以下土壤水分变异系数明显降低.除个别经验关系预测精度较差外,0~50 cm范围内各层与50 cm以下深层水分间的拟合效果较好,其相对误差均在4.7%内.利用0~50 cm水分进行深层水分预测,相对误差小于1%的占34.7%,介于1~3%的占55.6%,与其它0~50 cm内各层的预测误差相比明显偏低.因而
- Abstract:
- In the bloom growth stage of the cherry tree,Trime soil water system was used to measure soil water of cherry orchard and the curve between soil water and soil depth and models is founded using surface soil water to forecast deep soil water.The results showed that the variance of 0～90 cm soil water was more evident,and the variance coefficient of below 0～90 cm decreased obviously.Furthermore the corresponding effects of various layers less than 50 cm and more than 50 cm deep soil water were better except for one or two experience expressions,and the relative error of results were less than 4.7%. The relative error of results less than 1% and between 1% and 3% accounted for 34.7% and 55.6% respectively,which were obviously less than the relative error of results of other layers less than 50 cm,when the deep soil water was forecasted with 0～50 cm soil water.As a result,the various layers less than 0～50 cm could be to forecast better deep soil water in this region,but the forecasting precision of 0～50 cm layer was the best.
