摘要:: 以油菜秸秆为草浆原料，以豌豆为供试作物，采用对比方法，研究了3.0、1.5、0.75 g/盆（以不处理为对照）不同草浆用量对土壤水分和温度变化，以及草浆地膜覆盖对豌豆早期生长发育的影响。结果表明：随着草浆覆盖量的增加，0～5 cm深度土壤温差呈现温差减小的趋势，土壤相对湿度与土壤含水量呈增大的趋势，但以上指标处理间差异均不显著（P＞0.05，n=3）；不同草浆覆盖量处理间的豌豆种子出芽率基本相同，但高于对照（CK），出芽率处理间差异不显著（P＞0.05，n=3）；各草浆地膜处理下的豌豆株高均高于CK，株高依次为B＞A＞C＞CK，草浆地膜处理下的SPAD小于CK，但随着覆盖量的增加，叶绿素含量呈现降低的趋势，处理间数值差异极小；草浆地膜覆盖处理阻碍了土壤水分散失，保水效果明显，从而有利于豌豆植株的生长。

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.
