宁夏宜机收玉米品种的初步筛选
|
摘要
2015～2017年在宁夏扬黄灌区和引黄灌区开展239品/次适宜机械粒收玉米品种筛选试验。通过综合比较品种丰产稳产性、收获时子粒含水率等指标,筛选出3个适宜扬黄灌区机械粒收玉米品种,分别为银玉137、ZH846和先玉335。与对照郑单958相比,推荐品种早熟2～6.5 d,子粒含水率降低1.6～5.3个百分点,产量增加1.9%～12.2%。筛选出5个适宜引黄灌区机械粒收品种,分别是农华213、迪卡519、辽单575、登海605和先玉335。与对照郑单958相比,推荐品种早熟2～8 d,子粒含水率降低3.8～4.8个百分点,产量增加6.3%～18.7%。
To select maize cultivars suitable for mechanical kernel harvest in the Yellow River surrounding and supplement irrigation areas in Ningxia, China, an experiment involving 239 harvest data of cultivars were conducted from 2015 to 2017, and the cultivars' characteristics, that is, yield, stability, growth period, and grain moisture con-tent at harvest were analyzed. Then, 3 maize cultivars suitable for mechanical kernel harvest, that is, YY137,ZH846, and XY335, were selected for the Yellow River supplement irrigation areas in Ningxia. Compared with ZD958, the 3 recommended cultivars are 2-6.5 days early, the grain moisture content decreased from 1.6% to 5.3%,and yield increased from 1.9% to 12.2%. In addition, 5 suitable maize cultivars for the Yellow River surrounding ir-rigation areas in Ningxia were selected, which was NH213, DK519, LD575, DH605, and XY335, and compared with ZD958, the selected cultivars are 2-8 days early, the harvested grain moisture content decreased from 3.8% to 4.8%, and the yield increased from 6.3% to 18.7%.
