始于1978年实施建立面积为227亩的屏边县杉木种子园,1984年开始挂果;至1991年底,已先后为县内外提供杉木良种800多公斤。几年来的生产实践证明,种子园的种子质量明显高于普通生产种,种子发芽率高达51％,达到国家一级种子标准。采用种子园种子营造的良种示范林,其树高生长势高于对比林43％。在营造杉木种子园的实施过程中,我们从屏边县的实际出发,主要抓住以下几个关键环节: 1、搞好园地的规划设计。屏边种子园园地选择在四周具有阔叶
Beginning in 1978, the establishment of an area of 227 acres of Pingbian County fir seed orchard, started fruiting in 1984; to the end of 1991, has provided more than 800 kilograms of Chinese fir seed. Years of production practice has proved that the seed orchard quality seeds were significantly higher than ordinary production, seed germination rate as high as 51%, reaching the national level of seed standards. The seed-type demonstration forest planted with seed orchard seeds had a higher height-growth potential than the contrast forest with 43%. In the process of building the fir seed orchard, we proceed from the actual situation in Pingbian County and mainly grasp the following key aspects: 1, do a good job planning and design of the garden. Screen seed garden choice in the surrounding broad-leaved
