[0035] 1 Test materials and methods

[0036] The seedlings used in the experiment were grafted seedlings of Honghua Magnolia Jiaohong No. 2 with healthy growth and basically the same plant height and ground diameter. This experiment was carried out in Wufeng County, Yichang City, Hubei Province.

[0037] In order to select the best application method in this experiment, the L9(34) orthogonal table was selected for the experiment, prohexadione calcium, paclobutrazol, and uniconazole were selected as test reagents, and three concentration gradients and three different concentrations were set for the three reagents. The times of application and the concentration gradient are as follows: 500, 1000, 1500 mg / l, the times of application are 1 time, 3 times, 5 times respectively, and there are 9 treatments in total. See Table 1 for the specific information of the treatments. Take 15 safflower magnolia grafted seedlings as plots and repeat 3 times. The experimental layout adopted a c...

Abstract

The invention discloses a dwarf culture method for magnolia wufengensis by using uniconazole. Magnolia wufengensis grafted seedlings are used as materials, a plant growth retardant is sprayed to the grafted seedlings before the grafted seedlings which survive after grafting grow rapidly, the plant growth retardant is 5% wettable powder of the uniconazole, the useconcentration is 1500 mg / L, and theplant growth retardant is sprayed five times in one growing season. The spraying method adopts foliar spraying, the front and back faces of all leaves of plants are sprayed until waterdripsfrom the leaveseach time, and the spraying interval is 10 days. The methodhas a remarkable dwarfing effect, easy operation and low cost, and provides ideas forsubsequent dwarfingof the magnolia wufengensis grafted seedlings, and the method has an important significance in greening and ornamental value of the magnolia wufengensis.

Description

technical field [0001] The invention belongs to the field of seedlings, relates to a dwarfing method for trees, and more particularly relates to a method for dwarfing safflower magnolia by using uniconazole. Background technique [0002] Magnolia wufengensis L.Y.Ma et L.R.Wang, also known as Magnolia wufengensis L.Y.Ma et L.R.Wang, is a new species of the subgenus Magnolia in the family Magnoliaceae. It was discovered by Professor Ma Luyi of Beijing Forestry University and his team in Wufeng, Hubei in 2004. And officially published in 2006. [0003] Magnolia safflower is a tall deciduous tree. It grows in the natural secondary forest at an altitude of 1500m. It can reach a maximum of 30 meters. It flowers first and then leaves. The flowers are large and fragrant. There are various series ranging from dark red inside and outside to white inside and pink outside, with the number of tepals ranging from 9 to 46 petals, which is an excellent landscaping material.
