ABT增产灵是中国林科院研制成功的一种高效广谱性植物生长促进剂,1991年我市在棉花上应用鄂西自治州种苗站生产的ABT增产灵试验、示范应用1万多亩。在苗、蕾期低温阴雨,伏初罕见渍涝,吐絮期久旱无雨的情况下,仍然获得了丰收,收到了明显的增产效果,为棉麦两熟制棉花壮苗、早发、稳产、高产找到了新的途径,现将情况小结如下。 一、ABT增产灵浸种促根长叶效果比“802”更优 1991年4月28日,土肥站用ABT(25ppm)和“802”(250ppm)浸棉花种子2小时30分钟,设清水作对照。
ABT Zenglingling is a kind of efficient and broad-spectrum plant growth promoter successfully developed by Chinese Academy of Forestry. In 1991, our city applied ABT Zengling experiment on cotton to seed production station in western Guangxi Autonomous Prefecture, demonstrating the application of more than 10,000 mu. In the seedlings, the bud stage of low temperature and rainy, volcanic early rare waterlogging, boll opening period of drought and no rain, still get a bumper harvest, received a significant yield-increasing effect, cotton and wheat two mature cotton seedlings, early onset, stable production , High-yield found a new way, the situation is summarized as follows. First, the ABT Zeng Ling Spirit of soaking seed to promote root long-leaf effect better than the “802” April 28, 1991, soil fertilizer station ABT (25ppm) and “802” (250ppm) dip cotton seed 2 hours and 30 minutes, .
