摘要
以工业废料经化学处理制取的植物生长调节剂“丰收宝”经1991年以来用于小麦等作物的种子处理、苗期水培、盆栽浇灌尤其是盆栽大田喷施，证明具有明显的增产效果．大田喷施增产达20％－50％，优于目前市售的其它叶面肥．本文着重研究了自制丰收宝对植物生理特性的调节作用．如根系的变化．叶绿素含量的提高，叶面气孔的部分关闭等，以探索其增产机理．
The plant growth regulator 'Bumper Harvest Treasure'prepared from industrial waste by chemical treatment has been proved to be very effective on yield increase through seed treating. seedling water Cultivating, pot cultivation irrigating,especialy pot cultivation and field experiments in spraying for crops such as wheat, cotton and sugar beet since 1991. Spraying it has made the yield increase by 20%~50%, having superiority over other leaf surface fertilizers being applied nowadays. Its regulative effects on plant physiological characteristics.such as the change of the root system,the increase of chlorophyll contents and the partial closing of stomata of the leaf surface,have been studied particularly to explore the mechanism of the yield increase.
