竹产区的群众习惯把竹林中的竹笋依照冬春季节竹笋膨大的大小分为冬笋和春笋。冬笋膨大形成的竹笋能部分构成竹林,这已被很多试验证明,但究竟哪一个时期,哪一个阶段萌动膨大的竹笋成竹多,退笋少,竹林产量高等,这些都是生产上急待解决的问题。针对这些问题,我们经过几年的试验研究,取得了一些初步认识,现将试验结果分述如下。一、研究方法本试验是从1974年冬开始,先后在桃江和益阳两竹产区设立标准地,每年进行观察记 Bamboo production areas of the people used to bamboo shoots in accordance with the spring and winter bamboo shoots inflated size is divided into winter bamboo shoots and bamboo shoots. Bamboo shoots formed by the enlargement of winter bamboo shoots can partly form bamboo forests. This has been proved by many experiments. However, which period and stage of which bamboo shoots are sprouting and expanding are few, fewer bamboo shoots are retired and bamboo production is higher. All of these are urgent solutions for production The problem. In response to these problems, we have made some preliminary understanding after several years of experimental research, and the test results are as follows. First, the research methods The test is from the winter of 1974, has Taojiang and Yiyang two bamboo production areas to establish a standard annual observation
