温室滴灌条件下土壤水盐特性的研究

Study on the Soil Characteristics of Moisture and Salinity under the Dripping Irrigation Condition in Greenhouse

滴灌是一种局部灌溉,高频次的滴灌与施肥必然引起湿润体微域内水盐运移的变化,并影响作物生理生态响应。对温室滴灌条件下土壤水盐特性进行了研究,结果表明,水分的浸润特性与盐分的运移受灌水量的多少、灌水间隔的时间、滴头的流量、滴头的特性影响较大。

The dripping irrigation is a kind of partial irrigation. High frequency dripping irrigation and fertilization arise nec- essarily the change that moisture and salinity in the micro-field of humid body, and affect the physiological and ecological response of crop. It is suggested that the soaking feature of moisture and the transportation of salinity is affected mostly by the amount of the dripping water, the interval of irrigation, the flux of the dripping head and the feature of the dripping head. However, it is left to be observed that what the essence and features of the motion of moisture and salinity would be.
