楠竹(毛竹)成材早,发展快,用途广,是一种很有经济价值的竹种。近几年来,我区楠竹生产有了很大发展,竹林面积不断扩大,竹林蓄积量和采伐量不断提高,在支援社会主义建设作出了贡献。但在繁衍过程中,普遍存在着退笋现象,据调查,在正常年景下,退笋率为43.7—58.2％。如迂到干旱年景,退笋率高达81.2％,给楠竹生产带来了极大的损失。因此必须研究解决,把退笋率降到最低限度,以提高新竹数量和质量。
Bamboo (bamboo) become useful early, rapid development, wide use, is a kind of very economical bamboo species. In recent years, there has been a great development in the production of bamboo in our district. The area of bamboo forests has been constantly expanding. The reserves of bamboo forests and logging have been continuously raised and contributed to the construction of socialist construction. However, in the process of multiplication, there is a common phenomenon of reeling bamboo shoots. According to the survey, under normal circumstances, the rate of bamboo shoots retired is 43.7-58.2%. Such as the circuitous dry years, the rate of as many as 81.2% of bamboo shoots, bamboo production has brought great losses. Therefore, we must study and solve the problem of minimizing the rate of returning bamboo shoots to improve the quantity and quality of Hsinchu.
