一、试验目的泡桐根部不定芽形成根蘖嫩枝的能力很强,特别是在温床内进行催根育苗或营养钵育苗时,由于床内温、湿度适宜,填充物透气性好,根穗上根蘖嫩枝萌发的更多。据观察,在大田埋根育苗时,每个根穗上可萌生嫩枝3条左右;在温床内则可达5～7条。为了减少多余根蘖嫩枝对养分的消耗,保证幼苗健壮生长,一般对多余的嫩枝要进行多次抹除。用这些抹掉的根蘖嫩枝进行扦插育苗,省林科所渭河试验站已于1966年试验成功。为了在泡桐根蘖嫩枝扦插育苗技术上作进一步探
First, the purpose of the experiment Paulownia root adventitious buds to form a strong ability of root twigs, especially in the hotbed for rooting seedlings or nutrition Bowl nursery, due to the bed temperature, humidity, filling good permeability, root spike Root tillering shoots germinate more. It is observed that in the field when the root nursery seedlings, each root spike can sprout about 3; in the hotbed up to 5 to 7. In order to reduce excess root tillers shoots on nutrient consumption, to ensure the robust growth of seedlings, usually on the extra shoots to be repeated to erase. With these erased root tiller shoots cuttage nursery, Linhe Weihe River Experimental Station has been successfully tested in 1966. In order to paulownia root tiller shoot cutting technology for further exploration
