PP333是一种非常有效的植物生长延缓剂,国内外的研究表明:其对生长的抑制能力比AVG和B9强,能有效地致矮并促进花芽形成,药效持续数年,使同化产物主要转向生殖生长,为果树增产提供潜力。 本试验始于1986年初夏,受山农大委托且由该校提供国外进口的14%可湿性粉剂和25%乳剂协助共
PP333 is a very effective plant growth retardant. Domestic and foreign studies show that its inhibitory ability to growth is stronger than that of AVG and B9, which can effectively shorten the flower bud formation and promote flower bud formation. The efficacy of PP333 persists for several years, Turn to reproductive growth, providing potential for fruit trees to increase production. The test began in early summer 1986, commissioned by the Shannong University by the school to provide imported 14% wettable powder and 25% emulsion to assist
