Cultivation techniques for new large-flowered geranium varieties
The large-flowered geraniums 'Coral', 'Ice Cave' and 'Scene' have a plant height of 30 to 40 cm, with round and large flower heads, good mass planting effect and few pests and diseases, making them excellent material for landscape applications.

What are the new large-flowered carnation varieties?
1. Variety introduction: In the late period of the "Ninth Five-Year Plan", the Flower Research Institute of the Yunnan Academy of Agricultural Sciences undertook the provincial Science and Technology Department's science and technology tackling project "Breeding of New Large-flowered Carnation Varieties", and has bred a group of new cut-flower carnation varieties (lines). Some of the new varieties, after small-scale trial planting by flower growers, have shown good production suitability and marketability. Four applications for new carnation variety rights were filed with the Plant Variety Protection Office of the Ministry of Agriculture of China.

Rare Large Stand of Endangered Natural Yew Trees Discovered in Zhashui, Shaanxi
A rare large stand of natural yew trees, numbering more than 100,000, has recently been discovered in Zhashui County, Shaanxi, which is located in the Qinling Mountains. Some experts say that the yew is an endangered tree species preserved from the Quaternary glacial period, and that the extensive area and large number of this natural yew forest are rare. It is understood that Zhashui is located on the southern slope of the Qinling Mountains, in the transitional zone between the subtropical and warm temperate zones, with abundant rainfall and a forest coverage rate of 78 percent. It is rich in plant resources and has been known since ancient times as a "natural medicine storehouse."

What tree is the large-leaf red-flowered black locust? An introduction to its cultivar characteristics
The large-leaf red-flowered black locust is a multi-purpose black locust cultivar bred in Germany. In 1999, Professor Yang Minsheng of Hebei Agricultural University introduced it to China from the Institute of Forest Genetics and Forest Tree Breeding in Germany. After nearly 5 years of introduction trials and demonstration planting, it was proven that the large-leaf red-flowered black locust has strong adaptability, can grow normally in the suitable areas for black locust in North China, and has shown very high economic value. The large-leaf red-flowered black locust has a fast growth rate, with a diameter at breast height reaching 9.5 cm at 3 years old; a large leaf yield, with pinnate leaves 45-60 cm long, longer than tetraploid black locust
