The invention discloses a method for quickly constructing a choerospondias axillaris mixed forest with a near-natural community structure, which comprises the following steps: by taking an existing natural secondary forest as an operating object, simulating a local top-level forest mode, selecting forest land, selecting tree species, constructing a construction mode and cultivating and managing. The method comprises the following steps: properly thinning and tending, complementarily planting choerospondias axillaris in a forest window, effectively maintaining the soil fertility and quickly recovering a community structure by utilizing the characteristics that the choerospondias axillaris grows quickly and has a large amount of fallen leaves, and performing organic matter coverage and community density regulation and control on target broad-leaved trees. The problems that traditional secondary forest transformation is large in risk, poor in structural stability, low in economic benefit and the like are solved. A local top-level forest mode is simulated, a community composed of an arbor layer I mainly comprising a deciduous plant choerospondias axillaris and an arbor layer II mainly comprising a lauraceae plant evergreen broadleaf plant is rapidly built, the optimal community recovery mode of a natural forest is achieved, the purposes of short recovery period, large annual growth and stable community growth are achieved, the production cost is reduced, and the economic benefit is increased. Wide production and application prospects are realized.

The invention discloses a method for rapid shaping of silk cotton wood grafted with Hokkaido boxwood and Jiaodong euonymus, and relates to the technical field of grafting methods. The silk cotton wood, Hokkaido boxwood and Jiaodong euonymus are all from the Celastraceae family, have strong affinity and high scion survival rate. Multi-site and multi-method grafting is performed on reserved main branches, side branches and tertiary branches by using bark grafting, bud grafting and "T"-shaped bud grafting to rapidly form evergreen broad-leaved trees, thereby achieving the purpose of rapid shaping and greatly shortening the maintenance time. In addition, through the action of a protective fungicide, the survival rate of the scion is ultimately greatly improved, and the overall survival rate reaches more than 99%.

The invention discloses an application of a PtoELF3.1 gene in creation of non-dormancy evergreen poplar, and belongs to the fields of biotechnology and molecular biology, and the poplar ELF3.1 gene is a protein encoding an amino acid sequence as shown in SEQ ID No.1. A PtoELF3.1 gene is targeted through a CRISPR / Cas9 gene editing system, and a populus tomentosa Ptoelf3.1 mutant strain is obtained. Compared with a populus tomentosa wild type (WT) plant, the Ptoelf3.1 mutant plant still keeps the phenotype of evergreen and non-dormancy of terminal buds and lateral buds under the short-day condition in autumn and winter. The invention shows that the poplar is insensitive to a short-day condition due to knockout of the PtoELF3.1 gene, and the response to seasonal change is lost, so that the growth state of evergreen and non-dormancy is maintained. The method has great application prospects in the aspects of improving photosynthetic carbon sequestration of forest trees, increasing the wood yield and creating ornamental tree germplasm.

Plants of the new cultivar are thornless. The new cultivar is an Elaeagnus, normally used for outdoor ornamental purposes.

The invention provides an urban evergreen forest and fallen leaf forest extraction method, which comprises the following steps of: obtaining image blocks in two seasons of late winter and early summer, and forming a data set I by all the image blocks in the two seasons; each image block comprises an urban forest land parcel and a non-urban forest land parcel; creating a label value of a non-urban forest land parcel; based on the trained random forest model, acquiring respective pseudo label data of the evergreen forest and the deciduous forest corresponding to the data set I; the label values of the non-urban forest land parcels and the label values corresponding to the pseudo label data of the evergreen forest and the deciduous forest form a data set III; training a deep learning model based on the data set I and the data set III; and based on the trained deep learning model, obtaining a probability graph of the urban evergreen forest and the deciduous forest. According to the method, the drawing precision of urban evergreen forest and deciduous forest distribution is improved.

A simple sandy evergreen arbor terminal bud protection device comprises an external protection cylinder, an internal extension cylinder is detachably arranged in the external protection cylinder, an expansion base is arranged at the bottom of the internal extension cylinder, a U-shaped supporting seat is arranged at the bottom of the expansion base, and a protection pointed object is arranged outside the external protection cylinder. The protection pointed objects are protection thorns, and the multiple protection thorns are arranged on the outer protection cylinder. Physical guarantee is provided for vertical growth and timber formation of pinus sylvestris and spruce, and the probability that terminal buds of nursery stocks are damaged by cattle and sheep is reduced by additionally arranging the simple protection cover at the terminal buds of the arbors manually.

The invention discloses a method for promoting ecological dormancy release and growth recovery of fringed iris, which comprises the following steps: performing gene silencing or gene knockout on fringed iris derived tissues or plant organs, the silent or knocked-out gene is an IjAMY3 gene, then obtaining a plant, and a protein sequence coded by a protein coding region of the IjAMY3 gene is shown as SEQ ID No.2. A VIGS technology is utilized to obtain a mutant with a silent fringed iris IjAMY3 gene, and it is found that the plant growth speed of the mutant is obviously higher than that of a wild type and a control group under the growth recovery condition; in addition, the expression quantity of IjAMY3 in the IjAMY3 gene silencing mutant is remarkably reduced compared with that of a wild type and a control group, the discovery enriches the understanding of the function of the AMY3 gene, it is clear that the function of the mutant is different from that in existing dicotyledonous plants for promoting ecological dormancy of monocotyledonous plants, and a theoretical basis is provided for cultivating new evergreen flower ground cover varieties.
