| 摘 要： | 为探明覆膜条件下深翻对春玉米干物质积累及转运的影响,以‘伟科702’为供试材料,在覆膜条件下设深翻（FS）和旋耕（FR）2个处理,测定并计算不同处理下干物质积累及转运。结果表明：吐丝期后,FR干物质积累量显著高于FS,且随生育进程差异增大。干物质最大积累速率、持续时间均表现为FR〉FS,最大速率出现时间为FS〉FR。FR吐丝后的营养器官的转运量、转移效率和对子粒贡献率均显著高于FS,各器官表现为叶〉茎〉穗部。

| Abstract: | With‘Weike 702＇as test material, the author adopted 2 kinds of tillage methods under plastic-filmmulching： sub-soiling measures（FS） and rotary tillage（FR）, to research the effect of different tillage methodson the change rule of spring maize dry matter accumulation and transportation. Results showed that： aftersilking, dry matter accumulation of rotary tillage and ridging with plastic film munching was significantlyhigher than that of sub-soiling and ridging with plastic film munching, and the difference increased with thedevelopment process. FR had higher dry matter accumulation rate and longer duration time than FS. Dry mattertransportation, transfer efficiency and grain contribution of FR were significantly higher than that of FS, andthe performance in different organs was leaf srem ear. |
