摘要
将野罂粟从海拔1 010 m的地区引种到海拔360 m的试验园圃进行人工种植方面的研究。结果表明,播种深度以8 mm为宜;播种量8 g/m2。野罂粟在春、夏、秋3季播种均可出苗生长,但以春秋播种为宜。春播苗1年内能完成群体开花、采种过程;秋播苗翌年比春播提早2个月开花;夏播苗遇高温多雨,长势最差。带土坨移植野罂粟幼苗成活率可达98%以上。
To study the Papaver nudicaule that introduced from the area at an altitude of 1 010 metres planted in nursery at an altitude of 360 metres, The results shows that the suitable sowing depth is 8 mm and the suitable density of seeds is 8 g/m^2. Papaver nudicaule can germinate and grow in Spring, Summer and Autumn, But it grows better sowed in Spring and Autumn. The seedling sowed in Spring can blossom and go to seed. The seedling sowed in Autumn can blossom in next spring earlier two months than sowed in spring. The seedling sowed in summer grows worst for hot and rain. The survival rate was above 98% when the seedings are transplanted with soil clod.
