Abstract：In this paper，taking pakchoi（Brassica rapa L.chinensis Group.）variety‘Siyueman’as experiment material，we studied the effect of 3 different soil moisture contents（with W1，W2，W3 said）on major soil physical trait and pakchoi growth in greenhouse in winter．The results indicated that along with the increase of soil moisture the 3 phases of soil were significantly affected，the soil thermal capacity was also remarkably augmented．The soil thermal conductivity and the rate of soil thermal conductivity were firstly increased then significantly decreased．The result of daily soil temperature changes in 5 cm，10 cm and 15 cm soil depth showed that the soil temperature of soil moisture between 55 %-70 % treatment was higher than soil moisture between 70 %-85 % and 85 %-100 % treatments. In the 15 cm soil depth，the daily range of soil temperature with soil moisture contents between 70 %-85 % was the minimum．When the soil moisture was between 70 %-85 %，pakchoi single plant yield was greatly improved，and the contents of chlorophyll and VC were also increased．
