- 摘要:
- 以大白菜为试材,采用浸提液及秸秆腐解添加方法,研究了小麦秸秆添加对大白菜种子发芽及苗期生长的影响,以期为禾本科作物秸秆在蔬菜生产中的利用提供参考依据。结果表明:秸秆浸提液影响大白菜种子发芽,0.01 g?mL-1处理提高了大白菜种子发芽率、发芽势和发芽指数,0.02 g?mL-1处理增加了大白菜种子鲜质量,0.03 g?mL-1处理提高了大白菜种子发芽率及鲜质量;与对照(0%)相比,未腐解条件下,1.0%处理抑制大白菜出苗,抑制率为16.67%,对生长指标影响表现为对照>0.5%>1.0%>1.5%>2.0%,随着秸秆添加量的升高大白菜生长受到抑制;腐解试验中,1.0%与1.5%处理提高了出苗率,与对照相比分别提高了4.76%和19.04%,经过一定时间的腐解,幼苗生长受抑制程度降低,2.0%处理地上部鲜质量降低74.53%,干质量降低73.13%,而1.0%与1.5%处理对大白菜出苗率有一定的促进作用。
- Abstract:
- 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 of 0.02 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 the 1.0% 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%.
