马来西亚绿丰复合肥“大力丸”产品作用机理

Functional Mechanisms of Greenfeed “Daliwan” Fertilizer

马来西亚绿丰公司复合肥“大力丸”,是一款以沸石硅铝酸盐为载体的新型缓释肥料。在各类经作包括蔬菜、果树的使用得到农户的认可。主要田间观察表现为叶片平展、具有光泽度、叶花芽提早、座果率高、果实发育良好、产品贮架期长等效果。本单位曾以肥料本身的特性如具有离子梯度、pH平衡者和持效水分长等因素,总结产品特性。在本篇报告中,将细化产品在根和树体发挥作用的所观察到的效果,结合现有科学文献所总结到的结果,并以本产品在各作物表现的数据,进一步综合归纳产品发挥作用的理论基础。从几个方面可归纳总结:在根系增加根际效益;根部吸收铵离子有助减少作物总体能量耗损;另外可诱导离子交换性磷的再利用。在叶片的表现,可提升铵态氮的同化能力,增加叶绿素含量;减少重金属对电子传递链的破坏;以及硅离子增加叶表光合速率能力等六大方面。

Greenfeed compound fertilizer,commercial name in China“Daliwan”,originated from Malaysia,is a slow release fertilizer based on aluminosilicate as carrier.In China’s application since 2016,“Daliwan”performed excellent in vegetables and fruit trees and gained much positive feedbacks from farmers.Basically,field performances observed included broader and flattened leaves,glossy texture on leaves,early budding,high fruit setting,even on fruit development and longer in shelf-life.In past research,we concluded these performances based on the fertilizer characteristics such as ion gradient activity,pH balancer and also water holding ability.In this report,we further concluded more on these mechanisms based on observation from different parts of crops.The main mechanisms we further summarized here were:root zone effect;ammonium nitrogen being supplied to avoid crops energy consumption on metabolism;induction of dissolution of unavailable phosphate ion.In leave performance,it is concluded to increase the assimilation of ammonium ion and the content of chlorophyll;inhibition of harmful effect of heavy metal to electron transport chain;and lastly,the increase on leaves photosynthesis rate by silica ion.
