采用新剂型 Ａ Ｂ Ｔ 生根粉在４ 种观赏花卉微扦插育苗上布设试验。通过试验，摸索出了新何氏凤仙和长春花，盆式嫩尖微扦插以７ 号新剂型 Ａ Ｂ Ｔ 生根粉 ５０ μｇ／ｇ 生根效果最好，生根率分别达到９８ ．５ ％ 和８５ ％ ；花叶蔓长春和现代月季全光喷雾微扦插生根效果以７ 号新剂型 Ａ Ｂ Ｔ 生根粉１００μｇ／ｇ 最佳，生根 率分别为９１ ．５ ％ 和９２ ．７ ％ 。微 扦插成活 的花卉幼 苗恢复生长快，成苗率高，生长健壮，抗逆性强。
A new dosage form A B T rooting powder was used to lay the test on four kinds of ornamental flower micro cuttings. Through the experiment, the new Hip Impatiens and Changchun flowers were found out. The best rooting effect was achieved with 50 g / g ABT 7 rooting powder with rooting rate of 98. 5% and 85% respectively. The rooting effect of all-photon spray micro-cuttage of Changchun and modern rose was the best with the new rooting powder of ABT7 100μg / g, the rooting rate was 91%. 5% and 92. 7%. Micro-cuttings live flower seedlings to restore fast growth, high rate of seedlings, robust growth, strong resistance.
