为了掌握松树嫁接技术和探讨适宜的嫁接时期,以培育嫁接苗建立无性系种子园,我们遵照毛主席“一切经过试验”的教导,于1973、1974年固定专人进行了松树嫁接试验,兹将试验情况总结如下。 一、嫁接时期:1973年3月至9月,每10天嫁接一次,每次嫁接10株,共嫁接18次,平均成活率93.3％,1974年2月下旬至4月上旬每5天嫁接一次,每次嫁接15株;
In order to master the pine grafting technology and explore the appropriate grafting period, to cultivate the grafted seedlings to establish a clonal seed orchard, we follow Chairman Mao “all tested” teaching, in 1973, 1974, fixed pine grafting expert test, we will test The situation is summarized as follows. First, the grafting period: March 1973 to September, grafted once every 10 days, each grafted 10, a total of 18 grafts, the average survival rate of 93.3%, 1974, late February to early April every 5 days grafted once , Each grafted 15;
