广东省台山红岭林木种子园,于1964年开始营建湿地松无性系种子基地,1970年开始生产种子。现有造林面积1,612亩,其中用1年生苗造林的56.3亩,仅占3.6％,其余96.4％均用纸袋苗上山定植。1970年前育苗所用的种子来源于广东省台山县沙栏公社,以后均采自本园经嫁接后结出的果实。实践证明,湿地松采用纸袋育苗造林,成本低,成活率高,生长较快,同时,造林又不受季节限制。现将我们进行湿地松纸袋育苗和造林的方法介绍如下: 一、湿地松纸袋育苗技术 (一)纸袋的制法:用旧报纸作材料(报纸含有印油,比牛皮纸较为耐腐烂),一斤旧报纸一般可做240个。每张分作8份,制成8个双层的纸袋,其口径为6-7厘米,高11-12厘米。
Hongling Forest Seed Park in Taishan, Guangdong Province started construction of the Pinus elliottii Clone Seed Base in 1964 and started producing seeds in 1970. The existing afforestation area of 1,612 mu, of which 56.5 mu of afforestation with only one year, accounting for only 3.6%, and the remaining 96.4% are sacked with paper bags. Before 1970 seedlings used in seedlings from Taishan County, Guangdong Province, Shala commune, after all collected from the garden after the graft fruit. Practice has proved that the use of paper bags of Slash pine plantation afforestation, low cost, high survival rate, rapid growth, at the same time, afforestation is not seasonally restricted. Now we carry out wetland pine bag culture and afforestation methods are described below: First, the wetland bag papermaking technology (A) the bag of the system: the old newspaper for the material (newspaper containing ink, kraft paper more resistant to decay), a pound of old The newspaper can generally do 240. Each divided into 8 parts, made of eight double-layer paper bag, the caliber of 6-7 cm, 11-12 cm high.
