| 摘 要： | 通过利用先进的土壤水分测量仪,对雷州半岛春季西瓜种植期间逐日的土壤含水量进行连续测量,初步弄清了砖红壤的水分迁移变化规律,在此基础上进行了西瓜最佳灌溉模式的初步研究,利用土壤含水量的测量结果来控制灌溉次数和每次灌溉水量,研究结果表明．在无需增加节水机具等投入的情况下,采用合理的灌溉模式比一般常规灌溉模式节水25．2％．如果能对每次灌溉水量进行有效控制和适当缩小西瓜种植穴的直径,节水效率还可进一步提高。

| Abstract: | Using advanced measure instrument for soil moisture, the author continuously measured the day-to-day soil moisture during the spring watermelon growth period in Leizhou peninsula and got the soil moisture change law of brick red soil. Based on it, the author carried out preliminary research on the optimum irrigation model for watermelon and used measure result of soil moisture to control irrigation times and water quantity. The research results showed that compared with normal irrigation model, the optimum irrigation model can save water at 25.2 percent without investment of water saving machine. If irrigation water quantity can be effectively controlled and the diameter of watermelon cultivation aperture can be properly lessened, the water saving efficiency can be farther enhanced. |
