Abstract:
With rape straw as straw pulp material,peat as test material,effect of 3.0,1.5,0.75 g/pot of different quantity of straw pulp film (no treatment as control)on the grow conditions of peas,the soil water thermal characteristics and plant growth were studied.The results showed that straw pulp mulch treatments prevent soil water and heat dissipation,the large amount of straw pulp cover,the more effect of preventing hydrothermal.With the increasing of straw pulp cover,temperature difference of soil with 0～5 cm depth was decreased,relative humidity and soil water content in soil showed increasing trend,there were no differences between treatments(P＞0.05，n=3).Different quality of straw pulp treatments budding rate was the same,budding rate with the treatments of straw pulp film was higher than CK,there were no differences between treatments(P＞0.05，n=3).Plant height with the treatments of straw pulp film was higher than CK,plant high in turn was B>A>C>CK,SPAD with the treatments of straw pulp film was less than CK,with the quality of coverage increases,chlorophyll content showed the increasing trend.The straw pulp film mulch had significantly improved the hydrothermal conditions,promoted the growth of peas.
