油用牡丹‘凤丹’不同种植密度试验分析

Analysis on several different density cultivationexperiments of oil peony‘Fengdan’

为了研究油用牡丹‘凤丹’不同种植密度对其生长和产量的影响,设置了0.4 m×0.5 m,0.6 m×0.7 m,0.5 m×1 m 3种密度试验,对其形态指标和产量指标进行测定,结果表明在该试验条件下,不同种植密度对油用牡丹的冠幅、株高、当年生枝条数、单株结果数、单株产量和种子百粒质量等指标有显著影响,其中株高与单位面积种植数呈正相关,相关系数为0.565,冠幅、单株结果数、单株产量、种子百粒质量与单位面积种植数呈负相关,相关系数分别为-0.646,-0.630,-0.880,-0.703。栽培密度0.5 m×1 m的综合表现较好,冠幅为77.33 cm,显著高于其他组,单株产量、种子百粒质量、单位面积产量等指标均高于其他2组,分别为99.95 g,32.48 g,133.13 kg。该试验对油用牡丹的科学种植及其产业发展提供了理论依据和试验参考。

In order to study the effects of different planting densities on the growth and yield of oil peonies,Three different density treatments of 0.4 m×0.5 m,0.6 m×0.7 m,0.5 m×1 m were conducted to determine their morphological and yield indicators.The results showed that under the experimental conditions,different planting densities had significant effects on several indicators of oil peony,such as crown width,plant height,number of branches born in the current year,fruit number per plant,yield per plant,and seed weight per 100 seeds.Among them,there was a positive correlation between plant height and the number of plants planted per mu,with a correlation coefficient of 0.565.Crown width,fruit number per plant,yield per plant The 100-seed weight of seeds was negatively correlated with the number of plants planted per mu,with correlation coefficients of-0.646,-0.630,-0.880,and-0.703,respectively.In this test condition,0.5 m×The planting density of 1 m was the best,with a crown diameter significantly higher than that of the other groups(77.33 cm).The yield per plant,seed weight per 100 seeds,and yield per mu were higher than those of the other two groups(99.95 g,32.48 g,and 133.13 kg,respectively).This experiment provides an important theoretical basis and experimental reference for the scientific planting and industrial development of oil peonies.
