近年来,我省每年可采集落叶松、红松、油松、刺槐、紫穗槐等三十多个树种种子五、六万斤,调进红松、落叶松等种子四、五十万斤,从数量上可基本满足造林用种的需要。但是,也存在着主要造林树种不足,种子质量低劣和树种单纯等问题。产生这些问题的主要原因是过去靠天然结种,不搞良种基地;靠外援,不搞自力更生;靠个人采种,不搞专业采种。加之,有的同志对林木良种工作认识不足,抓的不得 In recent years, Larch, Korean pine, Pinus tabulaeformis, Amorpha fruticosa and Amorpha fruticosa can be harvested in our province every year for 50,000 to 60,000 tons of seeds, and seeds of 40,000 kg , Which can basically meet the need of reforestation in terms of quantity. However, there are also some problems such as the lack of main afforestation species, poor seed quality and simple tree species. The main reason for these problems is that the past relies on natural breeding, does not engage in breeding bases; rely on foreign aid, do not engage in self-reliance; by personal seed, do not engage in professional seed. In addition, some comrades do not have enough understanding of the thoroughbred planting of forests and do no good to them
