不同覆盖方式对川中丘陵区春玉米干物质积累与转运的影响
Study on dry matter accumulation and translocation of spring maize under different mulching methods in hilly area of central Sichuan Basin
摘要
Abstract
In order to alleviate constraint of seasonal drought on spring maize in hilly area of central Sichuan Basin , a two-year experiment 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 mat-ter accumulation ,distribution and translocation .The result showed that ,comparing with CK ,the green leaf area and dry matter accumulation per plant of T1 significantly increased during the whole growth stages ,and the dry matter transloca-tion to grains increased by 54 .06% ~95 .05% ,and the accumulation of dry matter after anthesis increased 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 dry matter accumulation and dry matter translocation to grains ,as well as the dry mat-ter accumulation amount after anthesis ,and the yield increased by 15 .02% ~15 .85% comparing with CK .关键词
