The application provides a tea garden identification method and device based on satellite images, which comprises the following steps: determining a evergreen vegetation area of a to-be-identified area based on Sentinel-2 image data and Landsat image data of the to-be-identified area; and identifying a tea garden area from the evergreen vegetation area through a decision tree model; wherein the decision tree model is constructed based on the following features and the classification threshold values corresponding to the features: a tea leaf phenology feature index, a terrain feature, and a spectral index determined by a separability index, wherein the SI is used to reflect the spectral reflectance separability of the tea garden and other evergreen vegetation; wherein the tea leaf phenology feature index is determined by an enhanced vegetation index in month N and a land surface water index in month M; the SI between the enhanced vegetation index in month N and the land surface water index in month M is the largest compared with the SI between the EVI in any other month and the LSWI in any other month, and N and M are integers greater than 0 and less than 13.

A new and distinct cultivar of Elaeagnus plant named ‘NCEX1’ is disclosed, characterized by evergreen, showy silver foliage, fragrant flowers, and a rounded, compact plant habit. ‘NCEX1’ is a triploid cytotype producing seedless fruit, or infrequently fruit with a small amount of non-viable seed. 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.

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.
