栽植密度与氮肥用量对茎瘤芥茎瘤形态特征及空心发生规律的影响及相互关系

为探讨栽植密度与氮素施用量对榨菜茎瘤形态特征的影响及茎瘤空心发生规律,设置3个栽植密度(行株距为40 cm×40 cm、40 cm×30 cm、30 cm×20 cm)与3个氮素施用水平(100、300、500 kg/hm²),研究不同栽植密度与氮素施用水平对榨菜单茎质量、茎瘤横纵径、空心率及空心指数等指标的影响,并探讨茎瘤各形态指标与空心率的相互关系。试验结果表明,栽植密度30 cm×20 cm搭配300 kg/hm²氮肥施用时能够调控茎瘤形态指标,降低空心率,具有最优产量表现;而在40 cm×40 cm栽植密度下,增施氮肥显著促进茎瘤横纵径,但由于茎瘤空心高发,导致产量明显降低。同时,茎瘤形态特征指标与空心率的相关关系与通径分析表明,茎叶比、单茎瘤鲜质量、腋芽发生率、单茎腋芽发生数与茎瘤横纵径呈极显著正相关关系(r=0.57~0.75),而与菜形指数呈极显著负相关关系(r=-0.51);对茎瘤空心率直接影响较大的指标分别为茎瘤横径(1.91)与菜形指数(1.38),而其他指标均通过菜形指数作用于空心发生率(-1.24~-0.34),表明菜形指数是影响茎瘤芥空心发生的重要因素,其中横径的伸长为茎瘤空心发生的主要因子。     

不同种植密度对水生蕹菜生长指标的影响

为明确水生蕹菜适宜生长的密度,在设施大棚内,行距30 cm时,设置了20 cm(P20)、30 cm(P30)、40 cm(P40)3种不同株距,研究了不同密度对水生蕹菜生长指标和生物量积累的影响。试验结果表明,随着密度的增加,水生蕹菜的主茎高、叶片数和主茎粗均表现为P20P30P40,说明生长空间充足利于水生蕹菜单株生物量的积累,但密度过小也不利于水生蕹菜群体生物量的积累,表现为P30P20P40,因此在行距为30 cm时,最适宜水生蕹菜的生长株距为30 cm。

Growing on the street: Multilevel correlates of street tree growth in Montreal

Tree planting has been favoured in many North American cities, including Montreal which aims to increase its canopy from 20% to 25% in 2025. However, the mortality rate of street trees is especially high in the first few years after planting. Studies have shown that variables that are intrinsic to the tree and those related to its location, the urban form and the socio-demographic characteristics of the surrounding environment are significantly associated either with trees’ survival rate or with vegetation cover. In this research we examine variables that have statistical associations with tree growth, which is the diameter at breast height divided by the number of years on the ground, for approximately 28,000 street trees in Montreal. Independent variables were nested into three spatial scales: the tree (species and physical variables), the street section (urban form variables), and the census tract (socio-demographic variables). Multilevel models reveal that 65.51% of the growth variance is potentially explained by the species and planting physical conditions such as the east and north sides (positive associations with the growth), signage as an obstruction (negative association). 28.54% of the grow variance is potentially explained by the urban form, in our case building age (convex relationship with the growth), mixed zoning (negatively) and residential zoning (positively). At the neighbourhood level, although none of our variables is significant, 6.95% of the growth variance is be potentially explained by other missing variables. New planting programs should hence consider the urban form in order to improve tree growth.

Investigation of plant growth and flower performance on a semi-extensive green roof

Understanding of plant growth and flower performance is crucial for appropriate planting design. This study was aimed to understand characteristics of growth pattern and flower performance in green roof plants and how plant species diversity effect these characteristics. A semi-extensive green roof was installed in 2005 and 54 species plant species were planted in 10 cm and 20 cm of the substrate in Rotherham, UK. Thirty-two quadrats (50 cm × 50 cm) were set up through the combinations of plant species diversity (high and low), planting density (high and low). Percentage of coverage and height of each species were recorded at every month from February to November 2006 in these 32 quadrates. Flowering time of each species was studied every two weeks from February to November 2006. Flowering time was various from plants; some showed a very long flowering time, over five months whereas some finished flowering within two weeks. The growth characteristics of individual plant species over time were categorized into six patterns of coverage and vertical growth pattern. Spread of individual plants was larger in high diversity of plants than those in low diversity of plants. Number of flowering was higher and overall flowering term was longer in the quadrats of higher plant species diversity than those of lower plant diversity. However, these tendencies were affected strongly by the combination of species used. Therefore, it is important to be aware of individual plant growth characteristics such as plant size, growth pattern and flower performance for planting design.
