| 摘 要： | 利用基质育苗裸苗移栽技术进行短季棉麦后移栽连作是一种轻简化植棉新模式,其中适宜苗龄移栽是首要问题.试验地点在黄河流域棉区的安阳市,以中棉所50为材料,研究比较6个苗龄裸苗麦后移栽后的生长发育和产量特征.结果表明,提前育苗其现蕾期提前,苗龄每增加1d,从移栽到现蕾期大田气积温约减少4.33℃ ·d,但大龄苗积温利用率不高...

| Abstract: | Under the new wheat-cotton continuous cropping pattern,cotton substrate seedling and naked-root transplant is a main light and simple technique.Its primary target is to figure out the appropriate seedling age to transplant.This study was conducted to investigate the differences in growth,development and yield among six transplanting seedling ages for a short season cotton(Gossypium hirsutum L.),cv.CCRI 50,in Anyang,Yellow River Valley Planting Region.The main results were as follows: the accumulated air tem... |
