摘要
近年来,邯郸各地陆续兴起“凤丹”(Paeonia ostii T.Hong et J.X.zhang)种植。为指导当地生产,2018年邯郸市林业局对“凤丹”牡丹结果特性和丰产性进行了研究,结果显示,“凤丹”牡丹单株分枝数与果荚数呈极显著正相关,分枝数、果荚数与单株产量呈极显著正相关,可用分枝数预估果荚数,进而预估单株产量;百粒重与单株产量呈正相关,提高百粒重在一定程度上可提高单株产量。通过间作和纯作对比试验初步得出,在株行距不变的前提下,2种模式单株产量在0.01水平差异不显著,单位面积产量在0.01水平差异不显著。5年生“凤丹”产籽量2536.5 kg/hm 2,与5年生核桃(Juglans regia)间作,综合收益可达79080元/hm 2,生态效益和经济效益显著,值得在生产中推广。该研究对推进当地油用牡丹产业发展有重要意义。
In recent years,Fengdan cultivation has gradually risen throughout Handan.In order to guide the local production,Handan Forestry Bureau studied the fruiting characteristics and yielding ability of Fengdan peony in 2018.The number of branches per plant was significantly and positively correlated with the number of pods,the number of branches and the number of pods were significantly and positively correlated with the yield per plant,the number of pods can be estimated by the number of branches,then estimated the yield per plant.Positive correlation between hundred-grain weight and yield per plant.The yield per plant can be increased to a certain extent by increasing the hundred-grain weight.Preliminary results were obtained by contrast test of intercropping and single cropping:under the premise that line spacing of Fengdan plant was unchanged,two patterns,no significant difference in yield per plant at 0.01 level,no significant difference in yield per unit area at 0.01 level.5-year-old seedling production was 2536.5 kg/hm 2,intercropping with 5-year-old walnuts,total revenue up to 79080 yuan/hm 2.Ecological and economic benefits of walnut-Fengdan intercropping mode were significant.It is worth promoting in production.This experiment is of great significance to promote the development of oil peony industry in Handan.
