摘要
为了研究乔草组合林中不同种类草本植物的生长变化,本试验以天津市武清区4种纯乔木林(裸地、国槐林、金叶槐林、金叶白蜡林)为样地,在其林下分别种植草本植物(大豆、苜蓿、万寿菊),通过测定不同乔草组合中草本植物的生物量(鲜质量、干质量)及生长指标(株高、单株叶片数、单株总叶面积等),研究了不同种类草本植物在不同乔木林下生长的状况。结果显示,在3种不同的乔木林下,大豆在国槐林的生长量最高,在金叶白蜡林下的最低;苜蓿和万寿菊在金叶槐林下的生物量最高,在国槐林下的次之,在金叶白蜡林下的最低。不同草本植物在相同乔木林下生长状况均是与大豆组合较好且生物量较高,而苜蓿和万寿菊相对较低;3种乔木林下草本植物的生长状况最优组合为国槐+大豆、金叶槐+苜蓿、金叶槐+万寿菊;因此,在乔草组合中,大豆与国槐林组合较好,苜蓿和万寿菊与金叶槐组合较好,且生物量高。
In order to study the growth changes of different types of herbaceous plants in the arbor-and-grass combination forest,this experiment took four pure arbor forests(bare land,national locust forest,golden leaf locust forest,and golden leaf ash forest)as sample plots in Wuqing District,Tianjin.Under the forest,herb plants(soybean,alfalfa,marigold)and growth index(plant height,number of leaves per plant,total leaf area per plant,etc.)are planted separately.By measuring the biomass(fresh weight,dry weight)and growth indicators(plant height,number of leaves per plant,total leaf area per plant,etc.)of herbaceous plants in different arbor and grass combinations,the impact of growth was studied.The test results showed that:under the three different tree forests,soybeans had the highest growth in the national locust forest and the lowest under the golden leaf ash forest;alfalfa and marigold had the highest biomass under golden leaf forest and the second among them,the lowest under the golden leaf ash forest.Under the same arbor forest,.the growth status of different herbaceous plants under the same arbor forest was better in combination with soybeans and their biomass was higher,while alfalfa and marigold were relatively low;the optimal combination of growth status of the three kinds of arbor forest herbs was locust+soybean,locust+alfalfa and locust+marigold;therefore,among the combinations of arbor,soybean and locust forest were better,and alfalfa and marigold and golden leaf locust were better,and the biomass was higher.
