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。

n 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.
