不同栽培方式和不同密度下金花葵差异性

Differences of Different Cultivation Methods and Different Densities of Hibiseu manihot L.

以金花葵为试材,采用移栽和播种2种方式对金花葵进行栽植,通过调节种植株距,控制不同的密度,对比研究不同栽培方式以及不同密度对于金花葵生长的影响,以期探索张家口地区金花葵种植的适合栽培方式和密度。结果表明:移栽与播种2种栽培方式对于张家口地区金花葵株高、地径、叶片大小、花朵大小、花朵产量、植株鲜质量产量的影响均未出现显著差异,种产量和植株干质量也只是分别在株距为35、60 cm处出现显著差异,其它密度均无显著差异。说明移栽和播种2种栽培方式均比较适合张家口地区金花葵生长;农艺性状方面,金花葵株高均随株距的增加呈现减小趋势,且存在显著差异。金花葵地径随株距的增加而增加,2种栽培方式地径均呈现株距35 cm与70 cm显著差异。叶片大小整体随株距的增加呈现缓慢增加的趋势,但不同株距之间未出现显著差异。花朵大小随株距的增加呈现缓慢上升趋势,小株距金花葵花朵大小显著小于大株距;产量方面,金花葵花朵干质量和鲜质量产量均随株距整体呈现上升趋势,60~70 cm株距的花朵产量有明显优势。种产量更是呈现随株距增加而增加的趋势,株距70 cm种产量最大,35 cm最小,并且变化较为明显。除播种的株距60 cm的植株干质量以外,金花葵植株干质量产量和鲜质量产量与株距总体呈反比的趋势,且受密度影响不明显。

Hibiseu manihot L.was used as test material,two methods of transplanting and sowing were used to plant Hibiseu manihot L..By adjusting the planting distance and controlling the different density,the comparative study was carried out.Effects of different cultivation methods and densities on the growth of Hibiseu manihot L.were studied.The suitable cultivation method and density of Hibiseu manihot L.in Zhangjiakou were explored.The results showed that there was no significant difference in the effects of transplanting and sowing on the plant height,ground diameter,leaf size,flower size,flower yield and fresh weight yield of the flowering sunflower in Zhangjiakou.The yield and plant dry weight were only significantly different at the plant spacing of 35 cm and 60 cm,respectively,and there was no significant difference in other densities.It was indicated that the two cultivation methods of transplanting and sowing were more suitable for the growth of Hibiseu manihot L.in Zhangjiakou.The plant height of the flowering sunflower showed a decreasing trend with the increasing of plant spacing,and there were significant differences.The diameter of the Hibiseu manihot L.increases with the increase of the plant spacing.The diameters of the two cultivation methods were significantly different between 35 cm and 70 cm.The overall leaf size showed a slow increase with the increase of plant spacing,but there was no significant difference between different plant spacings.The flower size showed a slow upward trend with the increase of plant spacing.The size of the small plant spacing flower is significantly smaller than the large plant spacing.The dry weight and fresh weight yield of Hibiseu manihot L.flowers showed an upward trend with the plant spacing.The flower yield of 60-70 cm plant spacing has obvious advantages.The yield was increasing as the plant spacing increases.The argest yield of the plant was 70 cm,the smallest was 35 cm,and the change was more obvious.Except for the dry weight of the plant with a plant spacing of 60 cm,the dry weight yield and fresh weight yield of Hibiseu manihot L.were inversely proportional to the overall plant spacing,and were not significantly affected by density.
