苗木是造林工作的物质基础。苗木质量的好坏,直接影响造林成活率的高低。要想保证造林有良种壮苗,必须遵照毛主席关于“自力更生”的伟大教导,贯彻中央提出的“自采、自育,自造”的三自方针,林场最好有自己的苗圃,就地采种、就地育苗、就地造林。避免苗木长途运输,以保证苗木质量,提高造林成活率。国营桓仁县和平林场在一九六三年以前,造林用苗木都是从桓仁县苗圃运来的。两地距离八十华里,还要渡过一道江。由于交通不便,运苗时间较长,虽然进行包装,但因春风强烈,苗木长时间脱水,常发生苗木风干现象,所以造林成活率很低。而且运苗 Seedlings are the material basis for afforestation. The quality of seedlings, a direct impact on the level of survival rate of afforestation. To ensure afforestation has strong seedlings, we must follow Chairman Mao’s great teachings on “self-reliance” and implement the three-self principle of “self-harvesting, self-reliance and self-construction” put forward by the Central Government. The best forest farms have their own nurseries on the spot Seeds, nursery on the spot, local afforestation. Avoid seedlings long-distance transport, in order to ensure the quality of seedlings, improve afforestation survival rate. State-owned Huanren County Peace Farm Before 1963, afforestation seedlings were brought from Huanren County nursery. Two from eighty miles, but also crossed a river. Due to the inconvenient transportation, the transportation of seedlings takes a long time. Although the packing is carried out, because of strong spring breeze and dehydration of seedlings for a long time, seedling drying occurs frequently, so the survival rate of afforestation is very low.
