１９９０年春季从浙江引种早竹、雷竹、红哺鸡竹、乌哺鸡竹、角竹、高节竹，１９９１年从本省古田县引种黄甜竹。７个竹种引种当年造林成活率达到７６．２％～１００％，平均造林保存率达８６．２％。经过４～５年的培育，１９９５年每公顷竹笋产量达３６４９．５～１６１３５．５ｋｇ，产值达１９５１３．５～６４５４２．０元，经济效益显著，具有推广价值。本文根据试验结果，对其引种造林技术进行了全面、系统的研究与总结
In the spring of 1990, the introduction of early bamboo, thunder bamboo, red feeding chicken bamboo, black bamboo feeding, angle bamboo and high bamboo in Zhejiang Province from Zhejiang in 1991 introduced yellow sweet bamboo from Gutian County in our province. The success rate of afforestation of the 7 bamboo species introduced at that time reached 76.2% ~ 100%, and the average afforestation preservation rate reached 86.2%. After 4 to 5 years of cultivation, the yield of bamboo shoots per hectare in 1995 reached 3649.5-16135.5kg, the output value reached 19513.5-64542.0 yuan, with remarkable economic benefits and promotion value. Based on the test results, this paper comprehensively and systematically studied and summarized the introduction of afforestation technology
