In this experiment,the Chinese cabbage was used as material.Experimental carried with straw extract test and sow test used continuous cropping soil as substrate.With extract experiment,germination rate,germination potential,germination index,shoot dry weight and fresh weight were measured.And growth seedling and seedling index were determination after straw treatments,in order to supply references for wheat straw use in vegetables production.The results showed that the germination of Chinese cabbage seeds was effected with straw extract treatment.The straw treatment of 0.01 g·mL~(-1) raised the germination rate,germination potential,germination index.The fresh weight increased with treatment of0.02 g·mL~(-1),germination rate and fresh weight raised under 0.03 g·mL~(-1) treatment.Chinese cabbage seedling was effected by straw added to continuous cropping soil.The germination rate was inhibited with the1.0%straw treatment with no decaying management,the inhibitory rate was 16.67%compared with control.The effect of growth index showed CK(0%)0.5%1.0%1.5%2.0%.In decaying test,the treatment of 1.0% and 1.5% raised the emergence rate,as 4.76% and 19.04% compared with control.After decompose,the inhibition degree of seedling growth was depressed.To 2.0% treatment compared with the control,the top fresh weight reduced 74.53%,and the top dry weight reduced 73.13%.The seedling growth was promoted with the treatment of 1.0%and 1.5%.
