本着“百花齐放,百家争鸣”的原则,本刊已开辟读者来信栏。对本刊存在的各种问题,欢迎读者批评;属于学术见解不同的,也可各抒己见,展开争论,以求取得对某个问题的正确答案。现将海滨林场何庆赓同志的一封来信,全文刊登如下。 In line with the principle of “letting a hundred flowers bloom and a hundred schools of thought contend,” we have opened up a letter column for readers. We welcome readers’ criticisms of the various problems that exist in this journal. Those who belong to different academic opinions may also express their opinions and debate in order to get the correct answer to a question. Now a letter from Comrade Ho Ching-kan, a beachfront farm, is published in full below.
