Abstract

为充分利用自然资源,减轻土壤盐渍化,提高农田生产力,在内蒙古河套灌区以春小麦、玉米和向日
葵单作为对照,监测春小麦—向日葵复种对土壤水分、盐分和农田生产力的影响。结果表明:春小麦收获
前,春小麦—向日葵复种和春小麦单作0—100cm土层土壤水分低于玉米单作和向日葵单作;春小麦收获
后春小麦—向日葵复种、玉米单作和向日葵单作耕层土壤水分高于春小麦单作,20—80cm土层土壤水分
则低于春小麦单作。春小麦收获前不同种植模式的土壤盐分变化剧烈,春小麦收获后则变化平缓。不同
种植模式主要影响0—40cm土层土壤盐分,对40cm土层以下的土壤盐分影响较小。复种向日葵收获期
春小麦—向日葵复种耕层土壤盐分较春小麦单作、玉米单作和向日葵单作分别降低32.52%,16.70%和
24.92%,0—100cm土层分别降低13.32%,8.88%和12.07%。春小麦—向日葵复种的等价产量较春小
麦单作、玉米单作和向日葵单作分别高出126.01%,3.86%和3.21%。春小麦—向日葵复种可减少土壤盐
分,提高农田生产力,在河套灌区具有一定的发展前景.

In order to make full use of natural resources,reduce soil salinization and improve farmland
productivity,this experiment took spring wheat sole cropping,maize sole cropping and sunflower sole
cropping as control,the effects of spring wheat-sunflower multiple cropping on soil moisture,soil salinity
and farmland productivity were investigated in Hetao irrigation district.The results showed that before
spring wheat harvest,the soil moisture in 0—100cm soil layer of spring wheat-sunflower multiple cropping
and spring wheat sole cropping were lower than maize sole cropping and sunflower sole cropping.After
spring wheat harvest,soil moisture in top layer of spring wheat-sunflower multiple cropping,maize sole
cropping and sunflower sole cropping were higher than spring wheat sole cropping,but soil moisture in 20—
80cm soil layer were lower.Soil salinity of different cropping patterns changed drastically before spring
wheat harvest,but changed gently after spring wheat harvest.Different cropping patterns had great influence on soil
salinity in 0—40cm soil layer,but had less influence on soil salinity under 40cm soil layer.When multiple
cropping sunflower harvest,top soil salinity of spring wheat-sunflower multiple cropping were lower than
that of spring wheat sole cropping,maize sole cropping and sunflower sole cropping,by 32.52%,16.70%
and 24.92%respectively,and 0—100cm soil layer soil salinity were lower by 13.32%,8.88%and 12.07%
respectively.Equivalent yields of spring wheat-sunflower multiple cropping were 126.01%,3.86% and
3.21%respectively,higher than that of spring wheat sole cropping,maize sole cropping and sunflower sole
cropping.Spring wheat-sunflower multiple cropping could reduce soil salinity,improve farmland productivity,and
have a certain development prospect in Hetao irrigation district.
