这种情况有时会与广大种植户所期待的速效作用

  腐植酸由于性质特殊,且见效相对较缓,因而不同的作物在实际使用中表现出来的效果差异较大。据实际经验,腐植酸一般使用后,10天左右才有肉眼可观之效,多数情况下半个月后效果才较为明显。这种情况有时会与广大种植户所期待的速效作用相悖。

中国互联网   为满足这一潜在的市场需求,近来市面上有很多含有植物生长调节剂即“激素”的腐植酸肥料,往往使用后三四天便产生明显效果。这种肥料在生根、促进膨大、提高产量方面确有优势,但是长期大量使用含有植物生长调节剂成分的肥料,会引发果实畸形、作物早衰,严重影响种植户和消费者的长远利益。由于植物生长调节剂的特点就是速效性和高效性,所以,广大种植户在选择此类含有植物生长调节剂成分的腐植酸产品时,需要因地制宜,根据作物不同的生长阶段,科学、谨慎、合理地选用标明植物生长调节剂含量的腐植酸类肥料。 (农民日报)
