Abstract:

In the growth period of Lycium, according to soil moisture characteristics, the author full used of limited water resources and regulated soil moisture. Using time domain reflectometry, the soil moisture tendency and evapotranspiration water consumption rule of Lycium were studied by different irrigation in non-weighing lysimeter (test pit). The results showed that: the irrigation was an important factor in soil moisture in Lycium field, the soil moisture consumption main dependence irrigates supplemented; the consumption of Lycium significantly affected by the influence of soil moisture, the more moist soil, the greater the amount of water; growth by temperature and wolfberry the impact of different water conditions, water peak in January wolfberry from May to September, the highest monthly water consumption in July; the highest water consumption of 10 days in late May, respectively, in mid-June and late July; stages of the trend of water consumption were performance of the full fruit>flowering>vegetative growth>autumn fruit growing> utumn fruit harvest.
