近年来,生长调节剂在果树生产上运用不断扩大。特别是在矮化、促花、提高果实品质、克服大小年等方面,表现出比常规农业技术措施更加简便明显的优势。但在生产中难免出现一些问题,有必要在此提出,以期引起大家的注意。一、生长调节剂不能代替肥水生长调节剂虽然可以调节植物的生长发育,但必须有充分的肥水条件为基础。在缺少肥水的条件下,植物生长调节剂往往不能发挥调节作用,有时会造成不良后果。二、严格掌握使用浓度生长调节剂在 In recent years, growth regulators have been expanding their use in the production of fruit trees. Especially in dwarfing, promoting flowers, improving fruit quality, overcoming the size of the year and other aspects, it shows the advantages of simple and obvious than conventional agricultural technology. However, some problems inevitably arise in the production, it is necessary to put forward here, with a view to arouse everyone’s attention. First, the growth regulator can not replace the fertilizer growth regulator Although the plant can regulate the growth and development, but must have adequate fertilizer and water conditions as the basis. In the absence of fertilizer, plant growth regulators often can not play a regulatory role, sometimes with detrimental consequences. Second, strictly control the use of growth regulators in concentration
