伴生植物对杨梅土壤养分及果实品质的影响

Effect of accompanying plants on soil nutrients and fruit quality of Myrica rubra

以伴生植物鼠尾草、波斯菊、紫云英为研究对象,探究其对丁岙杨梅土壤养分、枝叶生长和果实品质的影响。结果表明,伴生植物波斯菊能显著提升杨梅土壤中有机质、硝态氮和速效钾含量,分别比对照增加7.9%、51.3%、23.8%;波斯菊和紫云英处理对丁岙杨梅新梢和叶片生长均有一定促进作用,梢长分别比对照增加8.1%、8.8%,叶面积较对照提高6.6%、8.4%;波斯菊处理对果实品质的提升作用显著,硬度、维生素C、总氨基酸、总糖、总酚含量分别比对照增加9.8%、32.4%、10.9%、16.9%、8.9%。综上,该研究筛选到适宜丁岙杨梅生长的伴生植物波斯菊,对杨梅土壤养分改良、枝叶生长和果实品质的提升均有显著作用。

Using accompanying plants sage,coreopsis and milk vetch as research objects,the objective of this study was to explore their effects on soil nutrients,shoot and leaf growth,and fruit quality of Myrica rubra cv.Ding′ao.The results showed that the accompanying plant coreopsis significantly increased the content of organic matter,nitrate nitrogen and available potassium in the soil,increasing by 7.9%,51.3%,and 23.8%compared with the control,respectively.The treatments of coreopsis and milk vetch have a certain promoting effects on the growth of shoots and leaves of Ding′ao.Compared with the control,the shoots length was increased by 8.1%and 8.8%respectively,and leaf area was increased by 6.6%and 8.4%.The treatment of coreopsis has a significant effect on the improvement of fruit quality.Compared with the control,the hardness and the content of vitamin C,total amino acids,total sugar,total phenolic was increased by 9.8%,32.4%,10.9%,16.9%and 8.9%,respectively.In summary,the present study screened the accompanying plant coreopsis that was suitable for the growth of Ding′ao,which has a significant effect on the improvement of soil nutrient,shoot and leaf growth,and fruit quality of Myrica rubra.
