研究了不同采收期对糯玉米杂交种‘申科糯1号’产量和品质的影响。结果表明:在7个不同的采收期下,糯玉米杂交种‘申科糯1号’产量和品质表现差异显著。随着采收期的推迟,产量逐渐增加,而品质呈现先增加后降低的趋势。当采收期为24 d,有效积温达到367.85℃时,产量和品质之间达到最佳平衡点,折合产量为9 238 kg/hm~2,品质综合评分为87.4分。该结果将有助于生产者在上海地区确定糯玉米的最佳采收期。
The effects of different harvest time on the yield and quality of waxy corn hybrid ’Shenke No.1’ were studied. The results showed that there were significant differences in the yield and quality of waxy maize hybrid ’Shenko No. 1’ at seven different harvest times. With the postponement of the harvesting period, the yield gradually increased, while the quality showed a trend of first increasing and then decreasing. When the harvesting period was 24 d and the effective accumulated temperature reached 367.85 ℃, the yield and quality reached the best balance point, yield was 9 238 kg / hm ~ 2, and the comprehensive quality score was 87.4. This result will help producers determine the optimal harvest time for waxy maize in Shanghai.
