不同播期对黄秋葵长势、抗病性和产量的影响
|
摘要
为在河北省推广种植黄秋葵,在安国、保定、邯郸、衡水和石家庄5个试验点进行黄秋葵分期播种试验,研究了不同播期对石秋葵1号、红玉和五福3个品种生长势、抗病性和产量的影响。结果表明:播期对石秋葵1号、红玉和五福生长势、抗病性和产量具有较大的影响,随着播期的推迟,3个品种的茎粗大致呈逐渐增高的趋势,株高呈先降后升的趋势(除2018年的红玉外),单株结果数则先增加后减少,单果质量(除五福外)逐渐增大;以4月20日、25日和30日为播期,得到的黄秋葵单株产量和折合667 m~2产量较高。综合得出,河北省黄秋葵种植以4月20日、25日、30日为播期最为适宜。
In order to promote the cultivation of Abelmoschus esculentus in Hebei province, five experimental sites in Anguo, Baoding, Handan, Hengshui and Shijiazhuang were selected to carry out the sowing date test. The effects of different sowing dates on the growth potential, disease resistance and yield of three varieties like 'Shiqiukui No.1', 'Hongyu' and 'Wufu' were studied. The results showed that sowing date had great influence on growth potential, disease resistance and yield of 'Shiqiukui No.1', 'Hongyu' and 'Wufu'. With the delay of sowing date, stem diameter of the three varieties increased gradually, plant height decreased first and then increased(except 'Hongyu' in 2018), fruit number per plant increased first and then decreased, and single fruit weight increased gradually(except 'Wufu'). The yield per plant and yield per 667 m~2 of Abelmoschus esculentus were higher when sowing date were April 20 th, 25 th and 30 th. It was concluded that 20 th, 25 th and 30 th April were the most suitable sowing dates for Abelmoschus esculentus cultivation in Hebei province.
