摘 要:研究了冬春季普通大棚、普通大棚+中棚2种设施处理及露地栽培对不结球白菜生长的影响。结果表明:普通大棚+中棚处理对空气、土壤的增温效果最好,比普通大棚提前4 d、比露地提早8 d促进种子出苗。幼苗在普通大棚+中棚处理中的生长速度优于普通大棚处理。成株的生长量等各项指标与露地相比差异极显著;‘新矮青'的叶宽、柄下宽、单株重和柄重等指标差异极显著,且普通大棚+中棚处理>普通大棚处理;‘新夏青'的各个指标处理间差异不明显。The cultural experiments were carried out under plastic house, plastic house + tunnel and open field to study their effects on growth of pak-choi(Brassica campestris L. ssp. chinensis Makino)in winter and spring. The results showed that the plastic house + tunnel had the best heating-up effect on air and soil. The seedlings cultured under plastic house + tunnel emerged 4 d earlier than those cultured under plastic house or 8 d earlier than those cultured in open field. The seedlings' growth rate was bet- ter under plastic house + tunnel than under plastic house. There were very significant differences in the adult plants' indexes between culture under plastic house + tunnel and open-field culture. Such indexes as leaf width,petiole bottom width,plant weight and petiole weight for the variety 'Xin' aiqing' cul- tured under plastic house + tunnel were very significantly larger than those cultured under plastic house,but there were not significant differences in those indexes for the variety 'Xinxiaqing' between both cultivation treatments.
