Study On Rosa Chinensis ’Minima’ Potted Flower Cultivation And Flowering Regulation Techniques

As the popularity of miniature flowers,"miniature" Chinese rose has become a leader,the demand on the market increases year by year,and the requirements for color and quality are getting higher and higher.The introduction of excellent new varieties,shortening the potted flower cultivation cycle,and the annual supply market have become an urgent problem for the industry.Based on the development of micro-potted rose,this study carried out research on micro-monthly pot-flower cultivation and flowering regulation techniques.By analyzing the growth and variation laws of the growth cycle,the effects of different measures on micro-dune dwarfing and plant type were explored,and high-quality,high-yield and low-cost were selected.Miniature potted rose varieties,designed to provide technical support for large-scale production.The main conclusions of this study are as follows:1.Miniature potted rose seedlings without seedlings:There are significant differences in growth and development traits between different varieties of mini-potted roses.The rootless seedlings’assland’ and ’Princess of infinity’ have higher cutting survival rate(96.67%)than other varieties;Growing ’Da Sailor’and ’Snow White’ performed best,and the above-ground part of the growing ’Princess’ grew best;the ’cherry ball’ grew fastest(46.55 mm)and the ’Miffy’grew the slowest.(35.11 mm).After the sparse,the ’cherry pellets’ grows fastest(high 84.68 mm),and the’skull princess’ is the slowest(63.55 mm high).The overall performance of ’Princess’,’Da Sailor’and ’Snow White’ is better.’Miffy’ is the worst.2.Miniature rose season flower cultivation:the growth rate of plant height and stem diameter of different varieties in the mini-potted rose season,the initial flowering stage,the flowering stage trait,the underground part growth traits and the aboveground flower trails,the ’Snow White’growth and balance,the festival Moderate,plant height is moderate,the number of administration of chlormequat is small(5 times),’Little Red Riding Hood’is the most(7 times);plant height and stem growth are thick,’sissi princess’ is good,and ’Roma’ is the worst.Root development,flower opening time(20.5 d)and incubation period ’strong sailor’ is the best,’Roma’ is the worst.3.Dwarf measures to control the plant height and plant type of mini-potted rose:Dwarf treatment on the plant height and plant type control of mini-potted rose,the topping treatment has the greatest influence on the plant type of ’Princess’,and the control is best;’Popular sailor’ is the best control,’Roma’ is the worst;smudge treatment ’sissi princess’,’Alice’ performance is obvious,’Alice’ reflects the worst.All kinds of measures comprehensively deal with ’Princess of infinity’the best performance,’Roma’ is the worst,and the comprehensive control influence is Princess of infinity>White infinity>Jin infinity>Elpaso>Massland>Massland gold>Estoril>Roma.Comprehensive performance,micro-potted rose growth in different periods,different varieties of different stages of growth traits are different,the incubation period ’sissi princess’cycle is the shortest,the least number of application control,the largest number of flowers per plant,the longest flowering period,’Roma’ Worst.
