Response of Spring Maize Soil Environment and Yield to Planting Patterns in Semi-humid Region of the Loess Plateau
In order to explore the dynamic changes of soil hydrothermal environment and spring maize growth under different planting patterns in semi-humid and drought-prone areas of the Loess Plateau
field positioning experiments were carried out in Huating Agricultural Technology Promotion Center of Gansu from 2017 to 2018
and six planting patterns were set up
which were flat seedbed with film mulching (WM)
flat seedbed with half film mulching (HM)
ridge-furrow with polyethylene film and straw mulching (MRM)
ridge-furrow with full film mulching (WRF)
ridge-furrow with straw mulching (SM) and flat seedbed without mulching (CK)
and the water and heat status of soil profiles in different fertility period of spring maize
crop growth characteristics
crop yield and components during harvest period were measured and analyzed. The results showed that the regulation of mulching planting pattern on soil temperature was mainly manifested in the seedling stage. The film mulching treatment had a warming effect compared with CK. During the whole growth period
the average soil temperature increased by 1.44~2.62℃
while the SM showed a cooling effect
with an average temperature lowering of 0.51℃. MRM
WRF
HM and SM had significant effect on moisture conservation during the whole growth period of spring maize. While
WM was not conducive to precipitation collection
it only had the effect of moisture conservation at the early stage of spring maize growth
with the increasing of crop water consumption at the middle and later stages
the soil moisture content was lower than CK. Compared with CK
the mulching method could increase the yield and water use efficiency of spring maize
among them
the WRF and MRM had the most significant effect. The yield and water use efficiency of WRF and MRM increased by 32.96% and 17.12%
33.45% and 18.66%
respectively. SM showed a reduction in yield
which was 11.84% and 9.93% lower than CK. Considering the soil hydrothermal environment
spring maize growth characteristics
yield
water use efficiency and other indicators
the ridge-furrow with polyethylene film and straw mulching was the best planting pattern in the semi-humid and drought-prone areas of the Loess Plateau. This study could provide a theoretical basis for rational selection of cover farming measures in the semi-humid and drought-prone areas of the Loess Plateau
and had important significance for the sustainability of farmland.
