Eeffects Of Different Containers On The Growth Of Photinia Fraseri And Its Container Cultivation Technology

Photinia fraseri is one kind of microphanerophytes and shrub,which has highly tolerance to drought,low temperature resistant,nutrient deficiency,and also has certain resistance to alkaline salt and drought tolerance ability but which not resistant to water logging.Because of the red tender leaves was called Photinia fraseri.It is widely used in landscape and occupied in market share than other landscape species.This study is the first use of large Photinia fraseri shaped container seedling experiment.Container seedling experiment by choosing different containers,different cultivation conditions on seedling survival rate,maintenance cost,to compare and analyze,in the end,by the analysis of the cost accounting and the economy,to explore a set of suitable Photinia fraseri cylindrical container seedling production technology regulation.At the same time the paper also elaborate container seedling types,the habits and landscape characteristics of Photinia fraseri and so on.The results of this study are as follows: 1.four kinds of cultivation under the condition of red Shi Nanzhu like seedlings,seedling planting growth index is better than the container seedlings.The container seedlings in bottomless containers seedling height,crown width and diameter optimal index,a bottom control root container seedlings times,gallon pot seedling is the worst.2.Maintenance cost is the highest gallon pots container seedlings,followed by the container seedling root of the maintenance cost control,minimum is planted seedling maintenance cost per plant;the nursery rate is the highest at the bottom of the control root container culture of Photinia fraseri container seedlings,followed by control root container seedlings,the nursery rate is the lowest in the planted seedlings;container seedling market significantly better in planted seedlings market.3.according to the nursery rate and the nursery unit price calculated per plant net profit,profit of container seedlings was significantly higher than that of non container seedlings,and control root container culture container seedlings of profit is higher than general gallon pots a culture container seedlings,4.Finally summed up a set of applicable in the production technology of Photinia fraseri container seedlings commodity codes to provide reference for the market.
