Method for increasing ornamental value of euscaphis konishii hayata saplings through PP333

Abstract

The invention relates to a method for increasing ornamental values of euscaphis konishii hayata saplings through PP333, and belongs to the field of gardening or gardening ornamental nursery stock cultivation. A PP333 leaf spraying or root irrigation method is adopted; the application concentration is 250-1000mg / L; for leaf spraying, PP333 is sprayed to leaves by using an agroatomizer till fog droplets drop down from the leaves; for root irrigation, soil covered by projection of tree crowns is thoroughly watered or roots are watered till liquids leak off from bottoms of plant pots; the most appropriate concentration for euscaphis konishii hayata of two years is 1000mg / L; the most appropriate concentration for euscaphis konishii hayata of three years is 250mg / L; the most appropriate concentration for euscaphis konishii hayata of four years is 500mg / L; the optimal tree year for increasing the ornamental values with PP333 is 3, and the optimal application mode is root irrigation.

Description

technical field [0001] The invention relates to a method for using PP333 to enhance the ornamental value of saplings of javelins, and belongs to the field of horticultural or garden ornamental nursery stock cultivation. . Background technique [0002] Crow's crow is an excellent native ornamental tree species under development. It can bloom and bear fruit in 4-5 years. There are few side branches and large pith, so it is easy to droop or wind, which greatly affects the fullness and ornamental value of the crown shape of young trees. Therefore, strengthening the management of factors affecting plant shape such as dwarfing of saplings is the key to improving the ornamental value of C. In horticultural technology, there are a large number of reports on the successful application of PP333 (paclobutrazol) plant growth regulator to control plant height and plant type. The method is simple, low in cost and strong in operability. But due to the late development time of Toona sine...

AI Technical Summary

Problems solved by technology

But due to the late development time of Toona sinensis, except that the subject group of the unit of the present invention carries out long-term biological characteristics, growth characteristics, and cultivation characteristics research, there is no report of relevant research both at home and abroad; characteristics, that is, how to effectively control the characteristics of few and long side branches, large pith, prone to partial crown, easy to sag or wind break; how to effectively apply PP333 to effectively control the internode spacing of plants, prevent excessive growth, and maximize vegetative growth. No waste; to maintain optimal height

Otherwise, it needs to be cultivated for more than 10 years and undergo plastic surgery to show its good ornamental value. However, it is still not possible to use PP333 for plant type control according to horticultural reports. It is urgent to research and develop PP333 according to the characteristics of the tree species. A method for improving the ornamental value of saplings by plant regulators, so as to show the ornamental value of saplings as soon as possible, realize and increase its economic value as soon as possible
