Abstract:
With a cultivated variety of Pakchio (Brassica campestris ssp.Chinensis L.) named‘Qing Geng Cai’ as experiment material.In the experiment field of Shangqiu Universtity，the numbers of leaves and the biomass per plant of ‘Qing Geng Cai’ treated with different water gradient (soil moisture content respectively were 80%-90%(water 1)，60%-70%(water 2) and 40%-50%(water 3) of field capacity)) and previous stubble crops (‘Qing Geng Cai’ ，Amaranthus tricolor L and Cucumis sativus L.) were studied.The results showed that，the number of leaves per plant was the highest under the second water gradient；under the same water gradient，the number of leaves per plant was presented as：previous stubble Cucumis sativus L.significantly＞previous stubble Amaranthus tricolor L.significantly＞previous stubble‘Qing Geng Cai’ except for the first water gradient.Fresh and dry weight per plant under the same previous stubble both were presented as：water 2 significantly＞water 3 significantly＞water 1；fresh weight per plant under the same water gradient was presented as：previous stubble Cucumis sativus L.significantly＞previous stubble Amaranthus tricolor L. significantly＞previous stubble‘Qing Geng Cai’except for the first water gradient；dry weightper plant under three water gradient all were presented as：previous stubble Cucumis sativus L.significantly＞previous stubble Amaranthus tricolor L.significantly＞previous stubble ‘Qing Geng Cai’.All above，the production of Pakchoi was highest when soil moisture content was 60%-70% of field capacity and previous stubble crop was Cucumis sativus L..
