早在三十年代我省就引种了少量的湿地松,通过多年引种证明,湿地松是深受群众欢迎的速生、优质的造林树种。近几年我场先后引进不少湿地松种子,从几粒到200多斤,通过不断摸索,在育苗技术上有了提高,达到了产苗多,保苗率较高,苗木质量好的目的。如1980年用13.4斤,发芽率为88.9%的种子育苗,产苗148,500株,成苗率85%,合每亩产苗5万株,每斤产苗11,083株(一般最高只达7,000株)。1年生苗高30.4厘米,地径0.61厘米。其中一级苗最多,占66%,三级苗很少,只占4%。现将湿地松育苗经验介绍于下:
As early as the 1930s, a small amount of Pinus elliotis was introduced in our province. After many years of introduction, Pinus elliottii is a fast-growing, high-quality afforestation tree popular among the people. In recent years, I have introduced a lot of field pine plant seeds, from a few grains to 200 kilos, through continuous exploration, seedling technology has been improved, reaching a lot of seedlings, seedling rate is higher, the purpose of good quality seedlings. For example, in 1980, 13.4 kg seed germination rate of 88.9% seedling nursery, 148,500 seedlings, seedling rate of 85%, 50000 seedlings per acre, 11,083 per kilogram of seedlings (usually up to only 7,000) . One-year-old seedlings 30.4 cm high, 0.61 cm in diameter. One of the largest seedlings, accounting for 66%, three seedlings rarely, only 4%. Now the experience of wetland pine seedlings introduced in the next:
