Embodiment 1

[0024] Effects of Growth Retardants on Growth of New Shoots of Photinia fragrans

[0025] Take 60 neatly trimmed Photinia fragrans and divide them into 3 groups. After 2 days of pruning, 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) purchased at random on the market with a pressure sprayer respectively, evenly spray from the top of the plant to the root, adopt leaf In the method of surface spraying, the spraying amount is based on the principle that the surface of all leaves is wet, and then the spraying amount is 15mL / plant every 7 days for 3 consecutive treatments. Measure the height H of the freshly drawn shoots with a ruler 30 days after stopping the spraying 2 , calculate the growth of new branches H=H 2 -H 1 , and calculate the average value of the new branch growth H in each group, and the statistical results are shown in Table 1.

[0030] Effects of growth retardants on ground diameter growth of Photinia fragrans

[0031] Get 60 neatly trimmed Photinia fragrans, divide into 3 groups, after pruning for 2 days, measure the thickness at 2 cm from the ground with a vernier caliper, and record it as M; Retardant and the growth retardant (15% paclobutrazol wettable powder) purchased at random on the market are evenly sprayed from the top of the plant to the root, and the method of spraying on the leaves is adopted. Treat with the chemical once every 7 days, and treat 3 times in a row, and the amount of spraying each time is 15mL / plant. 30 days after stopping spraying, measure the thickness at 2cm from the ground again, record it as N, then the increase in ground diameter = N-M, and calculate the average value of the increase in ground diameter in each group. The statistical results are shown in Table 2.

[0036] Effects of growth retardants on deformed leaves of Photinia fragrans

[0037] Get 60 neatly trimmed Photinia fragrans, be divided into 3 groups, after pruning 2 days, spray deionized water, the growth retarder of the present invention and the growth retarder (15% Paclobutrazol wettable powder), spray evenly from the top of the plant to the root, adopt the method of foliage spraying, the spraying amount is based on the principle of moistening the surface of all leaves, and then treat it with the medicine once every 7 days, and treat it continuously for 3 times. The spraying amount is 15mL / plant. Stop counting the deformed leaf number after 30 days of spraying, and find its mean value, and the statistical results are as shown in table 3

Abstract

The invention belongs to the field of garden plant cultivation, and particularly relates to a growth delaying agent suitable for photiniaxfraseri and a using method of the growth delaying agent. The effect of delaying the growth speed of photiniaxfraseri and saving the maintenance cost can be realized on the premise of ensuring the landscape effect.

Description

technical field [0001] The invention belongs to the field of garden plant cultivation, and in particular relates to a growth retarder suitable for Photinia fruticosa and its application method. technical background [0002] Photiniax fraseri (Photiniaxfraseri) is the collective name for the hybrid species of Photinia in the family Rosaceae. It is an evergreen small tree with a plant height of 4-6 meters. The leaves are leathery, oblong to obovate-lanceolate, and the new leaves are red in spring. The three seasons of winter and spring are red, the color of frost is thicker, and the color of low temperature is better. As a street tree, its pole stands like a torch; as a hedge, its shape lies like a fire dragon; with pruning and landscaping, its shape can be in various poses and with different expressions, and the landscape effect is beautiful. Photinia is named for its bright red shoots and young leaves. In spring and autumn, the new shoots and young leaves of Photinia fragr...
