火炬树,又名鹿角漆,是从北美引进的一种落时灌木或小乔木,在我国西北、华北和华中地区广泛栽种。它适应性很强,在山麓、河谷、沙滩、堤岸等条件湿润、肥沃的地方生长最好,而在岩石裸露、干旱少雨、土地瘠薄的荒山也能正常生长,它极喜光和干燥气候,因此在阳光充足的干旱阳坡和浅山丘陵,完全可以正常生长。它极耐旱。实验证明,把手指粗(1.5～2.0cm)的火炬树根埋入干土中,在无水、无雨的条件下,经历30余天,虽不出蘖,但依然有生命力,只要有雨或浇水后,根就吸水、生根、发芽而成活。因此在年降雨量400mm左右的干旱贫瘠地区,利用“鸡窝土”或不大的坑穴,完全可以进行造林。干旱山区,在雨季前整地造林效果会更好,基本上一次栽种即可成活。
Rhus typhina, also known as antler lacquer, is a shrub or small tree introduced from North America, widely planted in northwestern, northern and central China. It is highly adaptable and grows best in wet, fertile places such as foothills, valleys, beaches, and embankments, and it grows well in exposed, arid, barren barren hills, and is extremely light and dry. In the sunny arid sunny slopes and hills, can grow normally. It is very drought-resistant. Experiments show that the finger thick (1.5 ~ 2.0cm) of the torch tree roots buried in dry soil, in the anhydrous, no rain conditions, experienced more than 30 days, though not tiller, but still have vitality, as long as there is rain or After watering, the roots absorb water, take root, germinate and survive. Therefore, in arid and barren areas with an annual rainfall of about 400mm, afforestation can be fully accomplished by using “chicken-goose soil” or small pits. In the arid mountainous area, the afforestation effect will be better before the rainy season and can basically survive once planted.
