Abstract:
Abstract:Through a field experiment in the greenhouse,different irrigation quota in the case of a fixed irrigation cycle impact on green peppers growth,yield and water productivity in both autumn and winter were studied，to determine the suitability of irrigation regime.The results showed that when irrigation quota within a certain range，the height and stem diameter of green pepper with the increase of irrigation quota；but when irrigation quota was too large to reach 280 mm,irrigation would inhibit the reproductive growth of green pepper，cause peppers lower production,reduce water use efficiency；when irrigation quota was 260 mm,yield and water use efficiency were the highest,could be used as indicators of appropriate irrigation for drip irrigation of green peppers.
