| Abstract: |
| In order to alleviate constraint of seasonal droug
ht on spring maize in hilly area of central Sichuan Basin, a two year experimen
t was carried out to investigate the effect of plastic film mulching(T1), half
plastic film mulching(T2), wheat straw mulching(T3) and zero film mulching(CK)
on spring maize yield, green leaf area per plant, dry matter accumulation, dist
ribution and translocation. The result showed that, comparing with CK, the green
leaf area and dry matter accumulation per plant of T1 significantly increased d
uring the whole growth stages, and the dry matter translocation to grains increa
sed by 54.06%～95.05%, and the accumulation of dry matter after anthesis increas
ed by 5.56%～11.02%, and the dry matter distribution of kernels increased by 12.
61%～16.28%. The treatment of T1 could obtain maximum maize yield by improving d
ry matter accumulation and dry matter translocation to grains, as well as the dr
y matter accumulation amount after anthesis, and the yield increased by 15.02%～
15.85% comparing with CK. |
