PP-2003(植物动力2003)是德国三托罗公司最新研制的一种微量元素(铜、锰、锌等)液态鳌合肥料,多种作物施用后有明显的增产效果,作物品质改善,恢复生机能力和抗病性、抗鳌逆性。BR(芸苔素内酯)是国际上最新型的高效植物生长调节剂之一,为第六类植物激素,具有极高的生物活性和增产效果。为提供它们在桃树生产上应用的依据,进行试验探讨不同浓度PP-2003和BR-120对桃树枝梢生长、着果率、叶绿素含量和光合速率的影响。试验地在福建省顺昌县园艺场,红壤坡地,桃树为4年
PP-2003 (Plant Power 2003) is a newly developed liquid fertilizer of trace elements (copper, manganese, zinc, etc.) developed by Santorum in Germany. It has obvious yield increasing effect after various crops are applied, crop quality is improved, Viability and disease resistance, anti-Ao resistance. BR (Brassinolide) is one of the most advanced and efficient plant growth regulators in the world. It is a sixth class of plant hormones with high bioactivity and yield enhancement. In order to provide basis for their application in peach production, the effects of different concentrations of PP-2003 and BR-120 on peach shoot growth, fruit-bearing rate, chlorophyll content and photosynthetic rate were studied. Experimental site in Shunchang County, Fujian horticultural field, red soil slope, peach trees for 4 years
