摘要
为确定西南地区夏秋花椰菜的最佳播期,于2014年在云南通海地区分别设置了3个播种期：5月21日、7月11日、9月5日进行对比试验,研究播种期对不同熟性的花椰菜品种的生长发育和产量的影响。试验结果表明,播期对花椰菜生育期影响较大,且随播期的推迟而增加,平均每推迟1 d全生育期增加0.11~0.96 d。其次,随着播种期的推迟,早熟品种产量呈下降趋势,而晚熟品种则相反。因此,综合考虑生育期和产量因素,早熟品种在西南地区夏秋季宜提前至夏季种植,而晚熟品种则宜延后至初秋播种。
In order to confirm the best sowing date of summer-autumn cauliflower in southwest China,we set three sowing dates May 21 st,July 11 st and September 5th,and studied effects of the three sowing dates on growth,development and yield of ten cauliflower cultivars with different maturity in Tonghai of Yunnan province in 2014.The results showed that,firstly,sowing date affected the growth period of cauliflower greatly,and growth period increased and added by 0.11-0.96 days when the sowing date delayed for one day.Secondly,as the sowing date delayed,the yields of early-maturing cultivars declined,but the yields of late-maturing cultivars increased.Therefore,taking yield and growth stage into consideration comprehensively,for cauliflower cultivars of Southwest China in summer and autumn,it was suitable to sow the early-maturing cultivars insummer and the late-maturing cultivars in autumn respectively.
