果蔬玉米的适应性研究

Adaptability Research of Maize Used as Fruit or Vegetable

通过随机区组排列和定时定点系统调查的方法对果蔬玉米在新疆南疆的适应性进行了研究。结果表明,引种的8个果蔬玉米品种在当地均有良好的适应性,一年均可种两季,出苗率、果穗产量、品质均优于引种地,但品种间的生育期在后期略有差异;可溶性蛋白质含量均在授粉后21d达到最高峰,可溶性糖含量在授粉后23d(乳熟中期)达到最高峰。供试品种中美珍208、甜脆蜜、华珍等3个品种产量产值较高、病虫害少,而且玉米秆可作青饲料,在发展畜牧业上前景广阔,建议在新疆推广种植。

Adaptability of maize varieties used as fruit or vegetable in South Xinjiang was studied by randomized block design and fixed point-time system method of investigation. The results showed that the eight maize varieties introduced all had good adaptability in the South Xinjiang and could be harvested two times in one year. Their emergence rates, yields and qualities were better in the South Xinjiang than in the introduced region. 8 varieties had different growth periods. The peak of soluble protein content appeared at 21 days after pollination and the peak of soluble sugar content emerged at 23 days after pollination. Among the 8 maize varieties, Meizhen 208,Tiancuimi and Huazhen were better in yield, income and resistance against diseases and pests, at the same time,their stems could be used as animal feed.
