Problems solved by technology

[0003] However, most species of Euonymus are shrub species, which cannot meet the greening requirements of urban street trees. Two arbor-type tree species, Baidu and Southwestern Euonymus, must be selected.
Due to weak apical dominance and poor dryness of Euonymus species, even if these two arbor species are selected, it is difficult to cultivate a tree shape with straight trunks and open crowns with conventional seedling raising techniques, which greatly limits the development of Euonymus species.

Embodiment 1

[0036] 1) Tree species selection: choose the arbor type Baidu ( Euonymus maackii Rupr.);

[0037] 2) Sowing and cultivating young seedlings or transplanting young seedlings: collect mature seeds of Baidu, choose flat and fertile sandy loam soil, after plowing, fertilizing, and making beds, sow seeds before the soil freezes in autumn, and use ditch drills, with a row spacing of 80cm and a thick covering soil 3cm, after emergence, thin out the seedlings according to the spacing of 60cm; or according to the spacing of 60cm and row spacing of 80cm, transplant 1-2 year old seedlings in the fall of leaves in autumn or before germination in spring. grow;

[0038]3) Cultivate seedlings with flat stubble: Before germination in spring, the seedlings cultivated in step 2) are stubbled from the ground. After germination, select one strong sprout and erase the remaining sprouts. Loosen the soil, weed, water, and fertilize in time during the growing season , continuous cultivation for 1...

Embodiment 2

[0044] 1) Selection of tree species: the Euonymus plant suitable for street trees is selected from the arbor type Euonymus ( Euonymus hamiltonianus );

[0045] 2) Sowing and cultivating young seedlings or transplanting young seedlings: Collect mature seeds of Euonymus southwest, choose flat and fertile sandy loam soil, after plowing, fertilizing, and making beds, sow before the soil freezes in autumn or after the soil thaws in spring, and use ditching and row sowing , the row spacing is 120cm, the cover soil thickness is 2cm, and the seedlings are thinned according to the row spacing of 30cm after emergence; or according to the row spacing of 30cm and the row spacing of 120cm, the 1-2-year-old seedlings are transplanted in the fall of leaves in autumn or before germination in spring, and the soil is loosened, weeded and watered in time in summer. Water and fertilization to promote the growth of seedlings;

Abstract

The invention discloses a cultivation method for a big seedling of an arbor euonymus alatus street tree. The cultivation method comprises the steps: stumping a 1-2 year in-situ sown seedling or transplanted seedling on the basis of selecting Euonymus maackii Rupr. or Euonymus hamiltonianus, and forming a straight and tall trunk by virtue of an apical dominance produced after stumping to finish drycultivation with a street tree trunk requirement; and after carrying out secondary transplantion for 1-2 years, carrying out heading according to a street tree trunk height requirement, cultivating afirst-grade skeleton branch by virtue of the apical dominance produced after heading, and cutting back the first-grade skeleton branch in the second year to form a second-grade skeleton branch so asto finally finish the crown shape cultivation of the street tree. By using the method, the cultivation of the trunk and a crown can be finished within 6-10 years, the requirements of urban street trees for dryness and crown shapes are met, the height of the trunk reaches 2.5-4.0m, the trunk is strength and tall, the crown has three plies and six branches, the cultivation time is greatly shortened,and the arbor euonymus alatus tree serving as one of good tree species for urban greening can sufficiently exert advantageous characteristics and achieve an application value.

Description

technical field [0001] The invention relates to the field of nursery stock cultivation, in particular to a method for cultivating large seedlings of arbor-type Euonymus genus street trees. Background technique [0002] Euonymus tree species has many advantages such as strong stress resistance, strong adaptability, and high ornamental value. It is an excellent tree species for urban landscaping and has broad development prospects. [0003] However, most species of Euonymus genus are shrub-type species, which cannot meet the greening requirements of urban street trees. Two arbor-type tree species, Baidu and Southwestern Euonymus, must be selected. Due to weak apical dominance and poor dryness of Euonymus species, even if these two arbor species are selected, it is difficult to cultivate a tree shape with straight trunks and open crowns with conventional seedling raising techniques, which greatly limits the development of Euonymus species. The application of the species of the...
