摘要

[目的

]

研究秸秆和地膜双元覆盖条件对设施黄瓜结果期根系生长和根际土壤养分含量的影响

为北方寒旱区设施农业可持续生产提供理论依据和技术支持。[方法

]

以设施黄瓜为试材

采用日光温室试验和室内测定的分析方法。[结果

]

玉米秸秆加地膜的双元覆盖处理可明显增加根际土壤有机质、氮、磷、钾等养分含量

促进植株根系生长

其中0.72 kg/m

秸秆量并覆膜处理效果和推广性最佳

与对照相比

在结果后期提高根际土壤有机质、全磷、全钾、碱解氮含量及根系数、根冠比、总根长、根表面积、根系活力分别达20.83%

22.83%

5.16%

5.53%

73.24%

32.76%

秸秆和地膜复合的双元覆盖效果优于秸秆或地膜单一覆盖处理。

Abstract

[Objective] We selected the cucumber to study the coupling effect of surface coverage with plastic film and maize straw on root growth and rhizosphere nutrients during fruiting period in greenhouse in order to provide the theoretical and technical support for the sustainable production of facility agriculture in cold and arid regions of North China.[Methods] Greenhouse experiment and laboratory test were used in this study.[Results] Treatments of combined coverage with plastic film and maize straw improved the content of organic matter

P and K in soil

and promoted root growth of cucumber. Compared with the control treatment in later fruiting period in the experiment

the treatment with 0.72 kg/m2 of straw and covered with film produced the best effect

and the content of organic matter

total P

total K

nitrogen and root factor

root-shoot ratio

total root length

total root surface area

root activity were increased respectively by 20.83%

22.83%

5.16%

5.53%

73.24%

32.76%

65.42%

45.94% and 10.41%.[Conclusion] The double coverage of straw and plastic film produced coupling effect and was better than coverage with single straw or plastic film.
