建国以来,在党的领导下,四川省林木种子需要量随着造林事业的发展而有所增加。五十年代年需种子几十万斤,目前已达四百万余斤。在常用的四、五十个树种中,松、杉、柏、桉、喜树等需种量较大,共占总需量的40％,是四川的主要造林树种。1958年以来,四川森林资源遭到几次破坏,种源减少。近几年来,见种就采的情况仍然存在,种子质量难以保证。为了弄清种子质量现状,根据二十多年生产、科研单位的种检资料,结合当前种子经营管理情况,拟对几种主要造林树种种子现状作一分析,并探索改进途径,以保证和提高种子质量。
Since the founding of the People’s Republic of China, under the leadership of the party, the demand for tree seeds in Sichuan Province has increased with the development of afforestation. In the fifties, hundreds of thousands of kilos of seeds are needed, and now it has reached four million kilos. In the commonly used four or fifty tree species, pine, cedar, cypress, eucalyptus, camptotheca acuminata need a large amount, accounting for 40% of the total demand, is the main afforestation tree species in Sichuan. Since 1958, Sichuan’s forest resources have been destroyed several times, with fewer provenances. In recent years, seeing the seed mining situation still exists, the seed quality is difficult to guarantee. In order to find out the current status of seed quality, according to the seeding data of more than 20 years of production and scientific research units, combined with the current situation of seed management, it is proposed to analyze the status quo of seeds of several major afforestation species and to explore ways of improvement so as to ensure and improve Seed quality.
