    摘要:

    为了明确不同栽培模式对土壤性质与水稻生长的影响,优化吉林省盐碱稻区栽培模式。以吉粳88和吉粳111为供试材料,通过在中低度盐碱稻区设置传统精耙地栽培(对照)、旱平免水耙栽培、三增综合栽培3种不同栽培模式,并测定在3种栽培条件下土壤理化性质和水稻根系氧化活力及产量构成。结果表明,在土壤的改良效果方面,无论在低度盐碱稻区或中度盐碱稻区,与传统精耙地栽培相比较,三增综合栽培和旱平免水耙栽培可降低土壤容重和电导率,增加土壤总孔隙度和水溶性有机碳含量,表现为三增综合栽培>旱平免水耙栽培>传统精耙地栽培。在水稻生长方面,三增综合栽培和旱平免水耙栽培水稻成穗率、根系活力以及实际产量均高于传统精耙地栽培,其中三增综合栽培下,吉粳111和吉粳88产量平均为10 204.8 kg·hm-2和10 662.9 kg·hm-2,比旱平免水耙栽培增加了21.0%和22.2%,比传统精耙栽培增加了30.3%和26.2%。这些结果表明,三增综合栽培模式相对于旱平免水耙栽培和传统精耙地栽培有明显增产优势。

    Abstract:

    This study was to make clear the effects of different cultivation patter on soil properties and rice growth and optimize cultivation patterns in Jilin soda alkali-saline region.Using ‘Jijing 111’and ‘Jijing88’ as materials,three cultivation patterns including traditional harrowing cultivation(CK),dry leveling cultivation,three measures cultivation were adopted and effects of different cultivation pattern on soil properties,root activity and yield of rice were studied.The results showed that three measures cultivation and dry leveling cultivation could reduce soil density,EC and increase total porosity,WSOC than CK when rice were grown on low or medium soda alkali-saline region.As to soil improvement effect,the different cultivation patterns showed that three measures cultivation>dry leveling cultivation>CK.As to rice growth,percentage of productive tillers,root activity and yield in dry leveling cultivation,three measures cultivation were higher than those in CK.The yield of ‘Jijing111’ and ‘Jijing 88’ were 10 204.8 kg·hm2 and 10 662.9 kg·hm2 in three measures cultivation,increased 21.0%and 22.2%than dry leveling cultivation,and increased 30.3%and 26.2%than CK,respectively.The results indicated that the rice yield superiority in three measures cultivation was obvious compared with dry leveling cultivation and CK.
