忌以药代肥。植物生长调节剂是生物体内的调节物质,不能替代肥水及其他农业措施。即使是促进型的调节剂,也必须有充足的肥水条件才能发挥作用。尽管现在的调节剂加入了一些浓缩的氮、磷、钾和微量元素,但含量微乎其微,作用亦不大,故千万不能以药代肥。 忌改变浓度。作物对调节剂的使用浓度要求比较严格。浓度过大,造成作物叶片增厚变脆,出现畸形,或叶片干枯脱落,甚至全株死亡;浓度过小,达不到应有的效果。因此,不要随意加大或缩小浓度。
Avoid using drugs on behalf of fat. Plant growth regulators are biological substances in the body can not replace fertilizer and other agricultural measures. Even a facilitator must have adequate fertilizer and water conditions to work. Although the regulator now adds some concentrated nitrogen, phosphorus, potassium and trace elements, but the content is minimal, the role is not large, so do not use the drug on behalf of fat. Avoid changing the concentration. Crops regulators use the concentration of more stringent requirements. Concentration is too large, resulting in thickening of the crop leaves become brittle, deformities, or leaves fall off, and even the whole plant died; concentration is too small to reach the desired results. Therefore, do not arbitrarily increase or decrease the concentration.
