池杉(Taxodium ascendens Brongn.)、落羽杉(T.distichum (L.) Rich)原产北美,是良好的速生用材树种,也是优美的观赏树种。从本世纪初开始引入我国,现已在长江南北许多省市广为栽培。但目前种源困难,多以扦插繁殖。由于种苗不足,影响栽培的发展,这是生产上迫切需要解决的课题。我们在池杉和落羽杉嫩枝扦插全光育苗的基础上,又应用其嫩枝进行水养育苗快速繁殖的研究。现将研究试验报道如下,以供参考。 Taxodium ascendens Brongn., T.distichum (L.) Rich native to North America, is a good growing species, is also a beautiful ornamental tree species. Introduced to our country since the beginning of this century, it is now widely cultivated in many provinces and cities in the north and south of the Yangtze River. However, the current provenance, more cutting propagation. Due to lack of seedlings, affecting the development of cultivation, which is an urgent need to address the issue of production. On the basis of the whole shoot nursery shoots of Taxodium distichum and Taxodium distichum, we applied the twigs to research on the rapid breeding of nursery stock. Now the research reports are as follows for reference.
