雷竹是一种优良的笋用竹种,曾被人们称为:“江南第一笋”,具有“出笋早,产量高,味道美,效益佳”等优点。新造雷竹园,只要科学管理,就可达到:“当年栽竹,二年出笋,三年成林,四年投产,五年高产”的要求。现将新造雷竹林的建园技术要诀介绍于下:1.三个选择(1)新区选择制约雷竹生长的主导因素首先是水分条件,第二是气温。根据各地实践:新区的适生范围以年降雨量1200～1600毫米,年平均气温15～18℃,一月均温3～7℃,极端最低温-15℃,极端最高气温40.5℃,全年大于10℃活动积温4800～5300℃,年日照时数1800～2000小时,无霜期240～260天,上
Bamboo is an excellent kind of bamboo shoots, which has been called: “the first bamboo shoots in southern China”, with “early shoots, high yield, delicious taste, good efficiency” and so on. As long as the scientific management of the newly built Lei Chuk Yuen can meet the requirements of “bamboo planted in that year, bamboo shoots in two years, forest planting in three years, production in four years and high yield in five years”. The new technology is now building the thunder bamboo garden tips introduced in the following: 1. Three choices (1) New Area to choose to control the dominant factor in the growth of the first bamboo is the moisture conditions, the second is the temperature. According to local practice: the new area of suitable range of annual rainfall of 1200 ~ 1600 mm, the annual average temperature of 15 ~ 18 ℃, January average temperature of 3 ~ 7 ℃, the extreme minimum temperature of -15 ℃, extreme maximum temperature of 40.5 ℃, the annual Greater than 10 ℃ active accumulated temperature 4800 ~ 5300 ℃, annual sunshine hours 1800 ~ 2000 hours, frost-free period 240 ~ 260 days, on the
