不同覆膜方式及种植规格对鲜食玉米的影响

为优化贵州省荔波县秋延后鲜食玉米高产栽培技术，进行不同覆膜方式及种植规格田间试验研究。试验结果表明，不同覆膜方式及种植规格对鲜食玉米农科糯336的植株性状、果穗性状、果穗产量及经济效益均存在较大的差异。采用全膜覆盖，且种植规格为(40+80)×33 cm(51 000株/hm²)和(60+80)×28 cm(51 000株/hm²),鲜食玉米农科糯336的综合性状均较优、果穗产量及经济效益均较高，适宜在当地同类型气候种植区推广利用。

Effects of Different Film Mulching Methods and Planting Specifications on Fresh Corn in Libo County,Guizhou of China

In order to enhance the high-yield cultivation technology for fresh corn during the delayed autumn in Libo county, a field experiment was conducted to assess the effects of different film mulching methods and planting specifications.The study focused on the plant characteristics, ear characteristics, ear yield, and economic benefits of the fresh corn variety ''Nongkenuo 336''. The results showed significant variations in these parameters among the different treatments.Among the various film mulching methods and planting specifications tested ,the whole film mulching treatment with a planting size of (40+80)×33cm (51,000 plants/hm²) and (60+80)×28cm (51,000 plants/hm²) exhibited better effect. This treatment showed higher comprehensive characteristics, ear yield, and economic benefits compared to other combinations. As a result, ''Nongkenuo 336'' is recommended for extension and utilization in local areas with similar climatic conditions.
