摘　　要：于2022年6~9月份开展全面普查,调查了怒江州2021年苗圃情况(所有制形式、数量、面积、产苗量)、2017~2021年林木种子采收及供应采收状况、2021年苗木生产结构(树种、育苗总面积、产苗量)。结果表明:2021年怒江州规模级苗圃共425处,其中个体苗圃数量占88.47%,育苗面积和产苗量最大;面积大于66.7 hm^(2)的苗圃数量和育苗面积有限,但是产苗量却远高于面积小于或等于20 hm^(2)和面积在20~66.7 hm^(2)的苗圃;2017~2021年,怒江州各类林木种子年平均采收9102 kg,年平均实际用种量8842.2 kg,种子采收及供应量充足;2021年,怒江州规模级苗圃育苗以核桃为主,育苗总面积达到1117.3 hm^(2),产苗量9136.9万株。指出了目前怒江州林木种苗产业稳定发展,但个体苗圃育苗技术有待提升,种质资源保护、良种选育宣传不到位,苗木生产结构不平衡问题仍然比较突出,提出了未来应在个体苗圃育苗技术指导、种子采收供应、良种选育宣传以及苗木生产结构调整上下足功夫,为该地区发展林木种苗产业提供更多支持。This paper is to understand the development of forest seedling industry in Nujiang Lisu Autonomous Prefecture(referred to as Nujiang Prefecture).From June to September,2022,a general survey was conducted to investigate the nursery situation(ownership form,quantity,area and seedling yield),tree seed harvesting and supply harvesting situation from^(2)017 to 2021,and seedling production structure(tree species,total seedling area and seedling yield)in Nujiang Prefecture in 2021.In 2021,there were 425 large-scale nurseries in Nujiang Prefecture,of which the number of individual nurseries accounted for 88.47%,with the largest nursery area and yield.At the same time,the number and nursery area of nurseries with>66.7 hm^(2)are limited,but the seedling yield is much higher than that of nurseries with≤20 hm^(2)and 20~66.7 hm^(2).From^(2)017 to 2021,the average annual seed harvest of all kinds of forest trees in Nujiang Prefecture was 9102kg;the average annual actual seed consumption was 8842.2kg,and the seed harvest and supply were sufficient;In 2021,walnut was the main nursery in Nujiang Prefecture,with a total nursery area of 1117.3 hm^(2)and a seedling yield of 91.369 million.At present,the forest seedling industry in Nujiang Prefecture is developing steadily,but the seedling raising technology in individual nursery needs to be improved.The protection of germplasm resources and the promotion of improved varieties breeding are not in place,and the imbalance of the seedling production structure is still prominent.In the future,great efforts should be made in the guidance of seedling raising technology in individual nursery,seed collection and supply,the promotion of improved varieties breeding,and the adjustment of the seedling production structures,so as to provide more support for the development of the forest seedling industry in this region.
