胡敏酸是一种植物生长刺激素.为了促使烟草苗期生长迅速,提早定植.达到早收、高产,从今年烟草育苗开始分别在几个栽培烤烟的生产队进行了胡敏酸钠处理,并取得了较好效果.情况整理如下: 一、浸种:用0.004-0.01%浓度的胡敏酸钠溶液浸种,可以促使种子发芽快,而且发芽率高.江南公社嘎嘶三队先把种子用60℃温水浸一下,然后再分别浸在0.004%的胡敏酸钠溶液中和普通水中,经过12小时后,捞出放在25℃的温度条件下,保持适当的湿度进行催芽.经过36小时后,用胡敏酸钠溶液浸种的,发芽率已经达到80%以上,对照则一共需要经过6-7天.可以看出,用胡敏酸钠浸种的可以提早2-3天发芽,这就为播种后早出苗创造了有利的条件.
Humic acid is a plant growth hormone.In order to promote the rapid growth of tobacco seedling, early colonization. To early harvest, high yield, starting from this year’s tobacco seedling cultivation in several flue-cured tobacco production team conducted a sodium huminate, And achieved good results. The situation is summarized as follows: First, soaking: seed soaking with 0.004-0.01% concentration of sodium huminate solution, can promote rapid germination of seeds, and high germination rate. 60 ℃ warm water immersion, and then were immersed in 0.004% sodium hypochlorite solution and ordinary water, after 12 hours, remove the temperature of 25 ℃, maintaining the appropriate humidity for germination.After 36 hours After the soaking with humic acid sodium solution, the germination rate has reached more than 80%, while the control is required after a total of 6-7 days can be seen that with humic acid sodium soaking 2-3 days earlier germination, which It has created favorable conditions for early emergence after sowing.
