早园竹的别名有早竹、雷竹、燕竹,属于禾本科竹亚科刚竹属植物。所谓“早园竹”是由于其笋期一般在3月上旬至4月上旬,或者更早生长,因此被称为早园竹。因为早园竹的生长习性,故其主要分布在黄河中下游各地的河南、江苏、安徽、浙江、贵州、广西、湖北等省区。一般早园竹的杆高6~8 m,径长2.5~5.0 cm,中部节间长10.0~20.0 cm,杆呈不均匀生长形态,新杆呈深绿色,节紫褐色。适宜在年平均温度15~17℃,最低温度-13℃,年降水1 200 mm以上的地方生长。为了研究当地土壤对早园竹产生的影响,本文主要选择了河北省廊坊市作为主要实验基地。
Alba early morning bamboo alba have early bamboo, thunder bamboo, Yan bamboo, belongs to gramineous bamboo subfamily Phyllostachys. The so-called “morning garden bamboo” is due to its bamboo shoots are generally early March to early April, or earlier growth, it is called early morning bamboo. Because of early bamboo growing habits, so it is mainly distributed in the middle and lower reaches of the Yellow River in Henan, Jiangsu, Anhui, Zhejiang, Guizhou, Guangxi, Hubei and other provinces. General early bamboo pole height 6 ~ 8 m, diameter 2.5 ~ 5.0 cm, the central section length 10.0 ~ 20.0 cm, the rod was uneven growth pattern, the new pole was dark green, section purple brown. It is suitable to grow at the annual average temperature of 15 ~ 17 ℃, the lowest temperature of -13 ℃ and the annual precipitation of 1200 mm or more. In order to study the influence of local soil on early-morning bamboo, this paper mainly selected Langfang City of Hebei Province as the main experimental base.
