| 摘 要： | 土壤水分传感器测定土壤含水率从而指导灌溉,对于提高作物水分利用效率和产量都具有十分重要的意义。对番茄种植中产量与水分利用效率最佳的水分条件以及土壤水分传感器的最佳埋设位置进行了试验研究。结果表明,在开花坐果期土壤含水率下限控制在60%的田间持水率,结果盛期土壤含水率下限控制在75%的田间持水率是番茄生长的最优水分条件;同时,10-20cm土层土壤含水率能很好地代表计划湿润层内的平均土壤含水率(开花坐果期和盛果期R2分别达到0.95和0.85以上),把土壤水分传感器埋设于此土层深度比较合理。

| Abstract: | Soil moisture sensors are used to measure soil moisture content so as to guide irrigation,which has great significance for improving water use efficiency and crop yield.This study presents the best water condition for enhancing both the yield and the water use efficiency in tomato-planting field,and determines the optimal soil depth for burying soil moisture sensors.The results show that it is the optimal water condition for tomato growth when the lower limit of soil moisture content is 60% of field capacity at flowering and fruit bearing stage and 75%of field capacity at fruit stage;and meanwhile,the soil moisture content at 10-20cm layer may better represent the mean soil moisture content of the designed irrigation layer(R2>0.95and 0.85 for flowering and fruit bearing stage and fruit stage,respectively),so it is more reasonable to bury soil moisture sensors in the depth. |
