我市地处金沙江干热河谷地区。鉴于用裸根苗进行荒山造林成效甚微,于七十年代初开始采用容器苗造林,并总结出一套小容器、轻基质育苗技术,经三年重复试验,效果较好。现将研究方法和结果简介如下: 一、育苗试材和造林试验地概况1.供试树种:台湾相思(Acacia conf-usa),由广西钦州引入,种子发芽率50%。2.容器:为0.3毫米厚聚氯乙烯薄膜热压而成的圆形袋子。规格(底径×高)有2×9厘米、4×9厘米、6×9厘米、8×9厘米和7×18厘米5种。前四种在容器壁下部均
The city is located in the Jinsha River dry hot valley. In view of the bare bark afforestation afforestation with little success, began in the early 1970s container seedling afforestation, and concluded a small container, light substrate nursery technology, after three years of repeated tests, the effect is better. Now the research methods and results are summarized as follows: First, the nursery materials and afforestation test site 1. Test species: Acacia conf-usa Taiwan, introduced by Qinzhou, Guangxi, 50% seed germination rate. 2. Container: a 0.3mm thick polyvinyl chloride film made of hot round bags. Specifications (diameter × height) are 2 × 9 cm, 4 × 9 cm, 6 × 9 cm, 8 × 9 cm and 7 × 18 cm 5 species. The first four are under the container wall
