摘要
朝仓山椒无刺、优质,食用价值和药用价值极高,但存在落花落果十分严重的问题。为了提高其座果率,作者开展了一系列的试验。结果表明:人工授粉、增加雄株配置比例、雌株上嫁接雄枝、喷布GA3、枣丰灵、硼均极显著提高了朝仓山椒座果率,其中以人工授粉最高,达到了33.23%;雌雄株配比4∶1座果率可达到19.78%;雌株上嫁接雄枝、喷布GA3、枣丰灵、硼座果率均达到了17.5%以上,对提高朝仓山椒的座果率均有一定效果,但2,4-D效果不显著。
Zanthoxylum piperitum DC.var.inerme Makino is a spineless and high quality ash variety.It has an extremely high edible and medicinal value.But the fallen of flowers and fruits is a very serious problem in Shijiazhuang area.The author conducted a series of experiments to improve the fruit-set percentage.The results showed that measures such as artificial pollination,increasing proportion of male plants configuration,female plants grafting of male branch and spraying GA3,application of ＂Zaofengling＂ and boron could all significantly increase the fruit-set rate of Z.piperitum DC.var.inerme Makino.The effect of artificial pollination was the highest among these measures and the fruit-set rate reached 33.23%;the male plant and female plant lines configured to 4∶1 was better and the fruit-set rate reached 19.78%;the measures such as female plants grafting of male branch,and spraying GA3,application of ＂Zaofengling＂ and boron had good effects on the fruit-set rate,the fruit-set rate of all above treatments also reached above 17.5%.But 2,4-D had no effect on the fruit-set rate.
