极端高温天气条件对鲜食玉米/大豆带状复合种植模式下不同鲜食玉米品种生长的影响

为科学遴选适宜鲜食玉米/鲜食大豆带状复合种植的耐密、抗病、抗倒的鲜食玉米品种,为玉米大豆带状复合种植技术示范推广提供品种支撑。开展了11个鲜食玉米品种与鲜食大豆的带状复合种植试验。结果表明：在2022年夏季极端高温且持续时间较长的气候条件下,夏播不同鲜食玉米品种在双穗率、空秆率等植株性状及千粒鲜重、出籽率、结实率等产量性状上差异明显,其中晶白甜糯、虞珑糯1612、苏玉糯5号、苏科糯1801、苏科糯1901等5个品种结实率较高,表现出较强的耐高温能力；苏甜糯818、斯达糯41、扬甜糯104结实率较低,表现出较低的耐高温能力。

Effects of Short Days Shading and Topping Treatment on Flowering Timeand Yield of Spring Lentils

To scientifically select dense, disease-resistant, and lodging resistant varieties of fresh corn that are suitable for the banding compound planting of fresh corn/soybean, and provide variety support for the demonstration and promotion of the banding compound planting technology of corn and soybean. A belt compound planting experiment was conducted on 11 fresh corn varieties and fresh soybean. The results showed that under extreme high temperature and long lasting climatic conditions in the summer of 2022, there were significant differences in plant traits such as double spike rate, empty stem rate, and yield traits such as 1000 grain fresh weight, seed yield, and seed setting rate among different fresh corn varieties sown in summer, including Jingbai Tiannuo, Yulong Nuo 1612, Suyu Nuo 5, Suke Nuo 1801 Five varieties, such as Sukenuo 1901, have higher seed setting rates and exhibit strong high-temperature tolerance. Sutiannuo 818, Starnuo 41, and Yangtiannuo 104 have lower seed setting rates and exhibit lower high-temperature tolerance.
