常熟市虞山林场于六十年代开始引进毛竹,迄今已发展到1,700多亩。为提高毛竹经济效益,从1984年起,在石洞工区等地进行了毛竹笋、竹两用林的试验,现已取得较好的效果。9.6亩试验竹林总产值达1,739.64元,平均每亩产值181.21元,是一般材用竹林的2.51倍;总产笋量1,123.5公斤,平均每亩117公斤,是材用竹林的2.36倍。现将试验小结如下: 一、试验地概况 试验地设在本场石洞工区牛啃椿山东地的Ⅱ林班1小班竹林内,面积为9.6亩,地理位置北纬31°40′,东经120°43′,海拔20—30米。年平均气温15℃,年降雨量1,050毫米。土壤为厚层黄棕壤,
Yushan Forest Farm in Changshu City in the sixties began to introduce bamboo, so far has grown to 1,700 mu. In order to improve the economic benefits of bamboo, starting from 1984, Shidong Works and other places have carried out experiments on bamboo shoots and bamboo-used forests, and have achieved good results. The total output value of 9.6 mu experimental bamboo forest reached 1,739.64 yuan, with an average output value of 181.21 yuan per mu, which is 2.51 times of that of bamboo for general timber. The total bamboo shoot yield is 1,123.5 kilograms, with an average of 117 kilograms per mu and 2.36 times of bamboo groves. Now the test summary is as follows: First, the experimental site of the test The experimental site is located in the field of cattle bite chong shandongdong Ⅱ Lin class 1 small bamboo forest, an area of 9.6 acres, geographical location latitude 31 ° 40 ’, longitude 120 ° 43 ’, 20-30 meters above sea level. The average annual temperature of 15 ℃, annual rainfall of 1,050 mm. Soil is thick yellow brown soil,
