特早熟松花菜浙农松花50天不同播期与密度配合试验

Experiment on Different Sowing Time and Planting Density of An Exceptionally Early Maturing Cultivar ’Zhenong Songhua 50’

为确定特早熟松花菜新品种浙农松花50天在杭州地区的最佳播期和播种密度,设置6个不同播种期(6月24日、7月1日、7月5日、7月10日、7月15日、7月20日)和3个不同种植密度(30000、33000、36000株/hm^(2))复因子试验,比较分析不同播期与密度对植株性状、花球性状、产量及效益的影响。结果表明:浙农松花50天在7月15日播种、种植密度为36000株/hm^(2)时,松花菜单球质量最大,为775 g,产量最高,为28420 kg/hm^(2),实际产值也最高,为78156元/hm^(2),为最佳播期与密度组合,其次是7月1日播种、种植密度33000株/hm^(2)组合。

In order to determine the best sowing time and planting density of a new cultivar of exceptional early maturing cauliflower ’Zhenong Songhua 50’ in Hangzhou area,six different sowing dates (June 24th,July 1st,July 5th,July 10th,July 15th,July 20th) and three different planting densities (30 000,33 000,36 000 plants/hm^(2)) were set up in the complex factor experiment.The effects of different sowing dates and densities on plant traits,flower traits,yield and benefits were compared and analyzed.The results showed that the best combination of sowing date and planting density was July 15th and 36 000 plants/hm^(2),with the highest single head weight of 775 g and highest yield of 28 420 kg/hm^(2),and highest actual output value of 78 156 yuan/hm^(2).It was followed by the combination of sowing date and planting density with 33 000 plants/hm^(2) planted on July 1st.
