Study On The Specialized Operation System Of Phalaenopsis(Phalaenopsis Aphrodite Rchb.f.)in Nanjing

Phalaenopsis Mothorchid is a perennial herb of Phalaenopsis.It is very popular with people with its bright colors,beautiful blossoms and the shape of butterflies.Currently,it is mainly used for festival celebrations and indoor landscaping in the market widely.It occupies an important position in the flowers of the year.Phalaenopsis has broad application prospects,but it has a higher requirement for flowering.In recent years,some producers have been mismanaged and have caused plants to blossom before the sales season comes,either delaying flowering or poor flowering,causing serious economic losses.It is not an easy task to control the opening of high-quality flowers at the right time.Must pay attention to every detail in the production and management of Phalaenopsis,all aspects must be as complete as possible.This topic combines the production status of Phalaenopsis in Nanjing,and discusses the effects of planting techniques,pot changing techniques,daily growth,management techniques,flowering control technologies on the growth,development of Phalaenopsis,and the management and sales of seedlings;the establishment of a professional operating system in Nanjing,scientific management,and the promotion of flower development in the region.The results show that:1.The development and breeding of new varieties of Phalaenopsis should be based on the collection of germplasm resources,and the use of breeding techniques for specialized production in the greenhouse,to achieve the industrialization of seedlings.Phalaenopsis tissue culture should use MS medium for Phalaenopsis explants(flower stems,shoot tips,leaves,etc.)for tissue culture propagation.2.Determination of physicochemical properties of four different culture substrates(volume density,total porosity,pH,conductivity and cold resistance)and the growth and development of Phalaenopsis(Phalaenopsis leaf number,leaf length,leaf width,number of leaves)The most suitable cultivation substrate for Phalaenopsis growth and development is Aquatic A grade.Determination of physicochemical properties of four different culture substrates(volume density,total porosity,pH,conductivity and cold resistance)and the growth and development of Phalaenopsis(Phalaenopsis leaf number,leaf length,leaf width,number of leaves)The most suitable cultivation substrate for Phalaenopsis growth and development is Aquatic A grade.3.The experiment used four different fertilizer ratios(high nitrogen,high phosphorus,high potassium,and uniform fertilizer)for two safflower varieties Phalaenopsis 'Big Chili'and 'Phalaenopsis 'Flaming Phenix'.Foliar spraying and root application were carried out,and the chlorophyll content,leaf number,leaf,leaf area,number of flowers(including flower buds),flower diameter,flower length and root and leaf of each variety were determined during October-December.The NPK content was finally analyzed by data analysis.When N:P:K=1:3:2,the flowering quality of Phalaenopsis was significantly better than other treatments.4.In the cultivation and management technology system of Phalaenopsis,when the number of tissue culture seedlings leaves is 3-5,the roots are 3-4 roots,and the seedling height is 3-5 cm,they can be bottled and transplanted.Phalaenopsis seedling replacement basins should be changed according to the schedule table basin work,middle seedlings cultivation time is 3-5 months,when most of the seedlings double leaf spacing of 18 cm or more,into the 3.5-inch planting,management cultivation 6-7 after months into the flower processing.5.The daily maintenance of Phalaenopsis should follow scientific management.The optimum temperature for growth should be around 25?-30?.The water management time and time vary from season to season.Water temperature is controlled at 20? and ventilation is provided.Leaves leaf area water to dissipate as soon as possible to reduce the occurrence of disease,and prevent individual seedlings matrix too wet;Fertilizer application discipline:concentration from low to high,species alternately used,foliar spray fertilizer is very important;light requirements:according to the size of seedlings controlled in 5000-20000 LX,too strong to cause sunburn,too low is easy to cause leggy.Daily management found that Phalaenopsis seedlings have pests and diseases,should take appropriate measures in a timely manner,and to prevention-oriented and comprehensive prevention.6.During the management and sale of Phalaenopsis sinensis seedlings,the classification should be based on the number of flowering orchids,stem length and flower diameter.The packaging process should pay attention to the effects of changes in environmental conditions such as moisture and temperature on the orchid flower.
