摘 要

在矿山废弃地生态修复项目中,针对我国某些地区特定的矿山类型以及周边环境特点,经土壤改良之后再种植需要稀植的速生丰产林国桐,在林间套种喜阴的经济作物油牡丹,是一项很有推广价值的立体种植模式。本课题通过具体试验,在探索过程中,找到国桐林和油牡丹套种的的地理条件、水肥管护、开花结果等因素的影响,形成一个国桐林套种油牡丹的林下套种油牡丹的矿山废弃地生态修复的新模式,增加了具体生产实践操作的可行性,促进产学研的深度结合。

论文主要研究了移栽与否、套种与否、套种间距、原土与粪肥的混合比例等变量与油牡丹的生长状况指标的关系,通过分析所用变量与生长指标之间的定性与定量的关系,进而确定套种条件下的最佳种植条件和管护技术。

研究结果表明:移栽株龄为2年的凤丹牡丹组培苗更为合适;在最适条件下单独种植的凤丹牡丹与套种于国桐林中的凤丹牡丹生长的各项指标差异不大;套种间距为0.5m*0.8m时,凤丹牡丹生长状况更好;在施肥方面,当地黄土与粪便好氧发酵的堆肥混合比例为2:1时,凤丹牡丹生长状况更好。

关键词: 国桐林;油牡丹(凤丹);套种;最适条件

Abstract

In the ecological restoration project of mine wasteland, in light of the specific mine types and surrounding environment characteristics in certain areas of China, the fast-growing and high-yielding forest Guotong is planted after soil improvement, and the oily peony, an economic crop that enjoys shade, is planted in the forest. It is a three-dimensional planting model with great promotion value. In the course of exploration, the paper finds out the influence of geographical conditions, water and fertilizer management, flowering and fruiting, and forms a new model of ecological restoration of the mine waste land of oil peony planted under the forest, which increases the feasibility of specific production practice and promotes the deep combination of production, education and research. This paper mainly studies the relationship between transplanting or not, interplanting or not, interplanting spacing, mixing ratio of original soil and fertilizer and the growth status index of oil peony.

According to the results of the study, it was found that the plantlets were more suitable for lactiflora Paeoniae were more suitable for 2 years growth indexes of Paeonia lactiflora L. were not different from those of Paeonia lactiflora L. under the optimum conditions; the growth condition of Paeonia lactiflora L. was better when the interplanting distance was 0.5 m*0.8m; and the compost mixture ratio of local loess and manure aerobic fermentation was 2:1.

Keywords: national tung forest; oil peony (Fengdan); interplanting; optimum conditions
