为在我圃下湿盐碱地的条件育好水杉苗,我们遵照毛主席“人的正确思想,只能从社会实践中来,只能从社会的生产斗争、阶级斗争和科学实验这三项实践中来”的教导,在1975年秋季进行了水杉嫩枝秋插试验。在试验中,我们在水(PH8.0-8.5)里加入少量的纯硫酸,使水的pH值降到6.0左右,然后再用这种微酸水配制萘乙酸溶液,喷洒扦插苗及苗床,苗木成活率平均在90%以上,且生长良好。现将主要做法简介如下: In order to raise the metasequoia seedlings under the conditions of wetland and saline soil, we follow Chairman Mao’s correct thinking of man and can only come from the practice of society. Only from the three practices of social production struggle, class struggle and scientific experiment To "teach, in the autumn of 1975 Metasequoia sinensis autumn inserted test. In the experiment, we added a small amount of pure sulfuric acid into the water (PH8.0-8.5) to reduce the pH of the water to about 6.0, and then formulated the naphthalene acetic acid solution with this slightly acidic water and sprayed cutting seedlings and seedbed. The average survival rate of seedlings in more than 90%, and grow well. Now the main approach is as follows:
