ABT生根粉是一种高效、广谱性生根促进剂,具有补充植物插条所需外源生长索和促进插条内部生长素合成的双重功效,可提高难生根树种扦插生根率(15—90%),缩短生根时间(30%左右).提高苗木成活率。近年来,在农作物上应用ABT生根粉浸种、拌种、沾根、叶面喷施处理,增产幅度在8—30%之间;用它浸条处理的扦插条,苗木成活率达93%以上。目前,全国已建立省市级ABT生根粉推广分中心20余个,推广单位2万多个,应用的林农植物有460余种,扦插育苗2亿多株,农作物面积150余万亩。我省已有8个地市近40个单位(点)开始了ABT生根粉的推广应用。上饶地区成立技术推广协作组,1990年推广复盖面积达
ABT rooting powder is a kind of efficient and broad-spectrum rooting accelerant, which has the dual effect of supplementing exogenous growth cords required for plant cuttings and promoting auxin synthesis inside cuttings, and can improve rooting rate of cuttings of difficult-to-root rootstocks (15-90 %), Shorten the rooting time (about 30%), improve seedling survival rate. In recent years, crop application of ABT rooting seed soaking, seed dressing, roots, foliar spray treatment, the yield increase of 8-30%; with its immersed strips of cuttings, seedlings survival rate of 93% or more . At present, there are more than 20 ABT rooting powder promotion centers at the provincial and municipal levels in China, with over 20,000 promotion units, 460 species of forest farmers, more than 200 million cuttings and more than 150 million mu of crops. Nearly 40 units (spots) of eight cities and districts in our province have started the popularization and application of ABT rooting powder. Shangrao region set up a technical cooperation team to promote the coverage of up to 1990
