Because Tianzhu Mountain is located in the northern edge of the middle subtropical zone, the humid airflow along the river is blocked by Dabie Mountain and meets the cold air over the mountain area, which directly affects the climate change of Tianzhu Mountain. The annual average rainfall is above 1 0,900 mm, the annual fog 1 0,80 days, the frost-free period is 235 days, and the annual average temperature is 9.5℃ (the average temperature in July is 20℃, 1 month is -2℃). It is precisely because of the fresh and humid air, abundant rainfall and abundant water resources on the mountain that Tianzhu Mountain has lush vegetation, soft lines and rich products. It has been found that most mountainous areas are secondary forests. Tianzhu Mountain Forest Farm was established in 1958, which has created a large area of artificial forest. Among them, there are 8,000 mu of bamboo sea in Beiguanzhai, thousands of mu of Chinese fir forest at the tip of Tongluo, and large areas of pine trees in Yaoyaoping and Nanguanzhai, which are all over the mountains and lush. There are about 1 19 families and more than a thousand species of plants in Tianzhu Mountain. There are mainly Pinus massoniana, Chinese fir, camphor tree, Ligustrum lucidum, Melia azedarach, Robinia pseudoacacia, Liquidambar formosana, Tung oil tree, elm tree, Toona sinensis, oak, palm and tallow. Precious tree species include Rhododendron Huangshan, Pinus taiwanensis, Buxus macrophylla, Cephalotaxus fortunei, Andromeda, Purple Tree, Willow, Fragrant Fruit Tree, Taxus chinensis, Torreya grandis, Phyllostachys pubescens and so on. Dendrobium, Gastrodia elata, Ganoderma lucidum, Atractylodes macrocephala, Poria, Coptidis Rhizoma, Polygonatum sibiricum, Paeonia lactiflora, Lilium, Herba Lycopodii, and many other precious medicinal materials also attached to it, and grew heartily. Under the influence of vertical distribution, they form a natural vegetation layer, which makes Tianzhu Mountain more colorful and enchanting. Deep mountains and dense forests are an ideal kingdom for rare birds and animals. There are still tigers, leopards, civet cats, badgers and porcupines. Birds include long-tailed pheasant, black magpie and thrush. And there are all kinds of fish in the water, such as giant salamander. Tianzhu mountain area is rich in resources and has a long-standing reputation. "Qianshan County Records" said: "The taste of alpine tea, without roasting, is naturally fragrant." "It is very rare that there are no spontaneous people between cliffs." In Grain Rain season, tea leaves are harvested and stored. "There are many dragons and finches." . Flooded rivers roar and other places, all produce tea. Zhou Shu Tianzhu Mountain Tea was famous in Tang and Song Dynasties. The Collection of Ancient and Modern Books, Record of Food Goods, and Tang Shi Supplement all record that "the envoys of the Tang Dynasty went to the western regions and saw famous teas in the mainland, among which Zhou Shucha was regarded as a treasure". "Yuquanzi" said that "Li Deyu, a famous minister in the Tang Dynasty, loved tea, and invited the secretariat to send' Tianzhu Peak Tea'". Shen Kuo notes Meng Xi: "The ancients only talked about Yangxian (Yixing, Jiangsu), Guzhu (Changxing, Zhejiang), Tianzhu, Mengding (Ya 'an, Sichuan) and other teas". All the above four places produce famous tea, and only Tianzhu Mountain tea is good tea. The modern research and development of "Tianzhu Sword Millie" kept the sweet, fragrant and beautiful characteristics of Tianzhu tea, and won the prize in 1985 national famous tea evaluation exhibition. In addition, there are tremella and camphor. "Anqing Fuzhi" said that "the buried hill produces Chinese alpine rush, which can be used as a seat". Zhou Shu bamboo mat has a long history and exquisite craftsmanship, and has been selling well in and out of the province for a long time, and exported to Southeast Asia. In the second year of Qing Dynasty (A.D. 19 10), he won the first prize of Nanyang Games.

It has two sides, four branches and green leaves. The wind calls it "the thing of a thousand years". Pine trees, far from cliffs, have no weeds and shrubs, which are beyond human reach, and are sometimes lost in the sea of clouds. It will be sunny tomorrow, overlooking Wan Ren, approaching the blue sky, awe-inspiring, and it is indeed arrogant. "Tianzhu old pine, this is the first", and the new edition of Tianzhu Mountain Records calls this pine Tianzhu pine.
Jade pot pine, under the cliff southwest of Feilai Peak. Pine three stems: the left stem extends outward in an arc shape, shaped like a spout; The stem is straight and luxuriant, just like the pot body; The stem on the right is prismatic and bends towards the middle, just like the handle of a pot. It looks like a big jasper teapot as a whole.
