盆栽型观赏向日葵具有较高的观赏和经济价值,目前,北京市密云县的种植还是初期阶段。对试种品种的市场表现进行观察,认为北京发展盆栽型观赏向日葵经济是可行的,所以为能够筛选出更多品质优良的向日葵品种,开展了盆栽型观赏向日葵新品种筛选试验。试验安排7个品种:1为开心小矮人,2为玩具熊,3为阳光舞仔,4为哲布隆,5为欢乐火炮竹,6为红海星,7为阳光笑脸(对照)。试验采取随机区组排列设计,7个处理,3次重复。植株以常规管理,在植株整个生育期认真观察各品种的生长动态,生育期进程,盛花期性状,各品种主秆花花期长短及商品切花等级分级等情况。通过试验数据的对比分析,考虑各品种综合表现,认为:对照品种7,阳光笑脸表现最好;其次是品种1,开心小矮人表现第2,为本次试验选出的优良品种。
Potted ornamental sunflower has a high ornamental and economic value, at present, Miyun County, Beijing is still the initial stage of cultivation. Observing market performance of cultivated varieties, we think that it is feasible to develop potted ornamental sunflower economy in Beijing. Therefore, in order to screen more varieties of sunflower with good quality, we carried out the screening experiment of new potted ornamental sunflower varieties. The experiment arranged seven varieties: 1 for the happy dwarf, 2 for the teddy bear, 3 for the sun dance Aberdeen, 4 for Zhe Bulong, 5 for Artillery firewood, 6 for the red starfish, 7 for the sun smile (control). Randomized block design experiments, 7 treatments, 3 repetitions. The plants were routinely managed to carefully observe the growth dynamics, growth stages, flowering stage traits, length of flowering periods of the main stems and grade of cut flowers of the varieties throughout the growth period of the plants. Through the comparative analysis of the experimental data, taking into account the comprehensive performance of various varieties, that: the control species 7, the sun smile best performance; followed by the variety 1, happy dwarf performance second, the test selected for the elite varieties.
