Different straw lengths and burial modes affect the salt distribution in coastal saline soil and the regulation of salt stress resistance in tomato
Abstract
Aims
Soil
salinization
poses
a
significant
threat
to
global
agricultural
development.
To
enhance
the
effectiveness
of
saline
soil
improvement,
study
innovatively
utilized
combination
powder
straw
interlayer
and
topsoil
mixing
for
returning
field.
Methods
A
tomato
pot
experiment
was
conducted
compare
effects
different
lengths
(S50:
50
mm,
S10:
10
S2:
2
mm)
burial
modes
(Wi:
interlayer,
Wm:
mixing,
Wim:
mixing)
on
salt
distribution,
root
biochemical
indexes,

dry
matter
weight
above-ground.
Results
The
found
that:
(1)
distribution
significantly
influenced
by
method
returning.
Straw
mode
had
greater
impact
than
length.
(2)
S50Wim,
S10Wim,
S2Wim
treatments
exhibited
more
differences
vertical
non-uniform
salt,
thereby
promoting
regulation
roots
in
response
stress
effectively
mitigating
its
adverse
effects.
(3)The
treatment
can
improve
Compared
CK
treatment,
above-ground
increased
89.03%
(P
<
0.05)
59.28%

respectively.
Conslusion
It
concluded
that
combined
mm
(S2Wim)
optimize
coastal
soil,
promote
tomatoes
stress,
alleviate
ultimately
yield.
