[0023] Effects of Growth Retardants on Growth of New Branches of Ligustrum edulis

[0024] Take 60 neatly trimmed small-leaf privet plants and divide them into 3 groups. After pruning for 2 days, measure the plant height and record H 1 , spray deionized water, the growth retarder of the present invention and the growth retarder (15% paclobutrazol wettable powder) randomly purchased on the market with a pressure sprayer respectively, spray evenly from the top of the plant to the root, and use leaf For the surface spraying method, the spraying amount was based on the principle of moistening the entire leaf surface. After that, the pesticides were treated once every 7 days, and the treatment was continuous for 3 times. The spraying amount was 13 mL / plant each time. Measure the height H of the new shoots with a ruler 30 days after stopping the application 2 , calculate the new branch growth H=H 2 -H 1 , and the mean value of the new branch growth H in each group was obtained. T...

[0029] Effects of Growth Retardants on Growth of Privet Leaf Diameter

[0030] Get 60 neatly trimmed leaflet privet, be divided into 3 groups, after pruning for 2 days, measure the thickness at 2cm from the ground with a vernier caliper, denoted as M; The growth retarder and the growth retarder (15% paclobutrazol WP) randomly purchased on the market should be sprayed evenly from the top of the plant to the root, and the method of foliar spraying should be adopted. After that, they were treated with the chemical once every 7 days, three times continuously, and the spraying amount was 13 mL / plant each time. 30 days after the application was stopped, the thickness at 2 cm from the ground was measured again, and recorded as N, then the ground diameter increase = N-M, and the mean value of the ground diameter increase in each group was obtained. The statistical results are shown in Table 2.

[0035] Effects of Growth Retardants on Leaf Number of Privet Deformities

[0036] Get 60 neatly trimmed leaflet privet, be divided into 3 groups, after pruning for 2 days, spray deionized water, the growth retarder of the present invention and the growth retarder (15 % paclobutrazol wettable powder), sprayed evenly from the top of the plant to the root, using the method of foliar spraying, the spraying amount is based on the principle of moistening the entire leaf surface, and then treated with the chemical once every 7d, continuously treated 3 times, each time The secondary spraying amount was 13mL / plant. The number of deformed leaves was counted 30 days after the application was stopped, and the mean value was obtained. The statistical results are shown in Table 3.

Description

technical field [0001] The invention belongs to the field of garden plant cultivation, and in particular relates to a growth retarder suitable for privet leaflet and a method for using the same. technical background [0002] Ligustrum quihoui (scientific name: Ligustrum quihoui Carr.) is a small shrub of the genus Oleaceae; the main branches and leaves of Ligustrum quihoui are compact and round. It is an excellent anti-pollution tree species. Ligustrum folium has fast growth speed, strong adaptability, pruning resistance, strong germination power, and pruning resistance, and can be used in multi-functional, multi-level and three-dimensional applications according to the needs of gardens. It can be planted as a ground cover, and can also be used in residential areas, factory green spaces, streets or highway green isolation belts; generally cultivated into shrubs, spherical and natural shapes for hedges. [0003] However, due to the rapid growth of privet leaflets, it will c...
