有机活化剂对磷矿粉活化效果研究

研究以沙田柚为例的果树施用经有机活化剂活化处理磷矿粉的效果，结果表明，施用活化处理磷矿粉的轴树在各生育期的叶片养分状况比施用过磷酸钙和钙镁磷肥的好，所以在各时期的农艺性状表现良好，产量较高，在适当时期补充中微量元素可使沙田柚高产优质。研究结果显示，果树可直接和一年一次施用价格低廉的磷矿粉，采用活化技术可使磷矿粉的肥效超过磷酸钙和钙镁磷肥，从而可大幅度地降低果园的肥料和施肥用工费而降低生产成本，同时又可减少因施肥过量和磷肥生产而造成的浪费和环境污染，还可使造纸废液开发产品的利用而使工业废物作为资源利用而减少它的二次污染。

Briefing of Effect in Organic Activation Substance Activate Phosphorite Powder

This paper studied that effect of phosphorite powder were activated by organic activation substance in the fruit tree for exemple Cirtus grandis cv.Shatianyou.The result indicate that the nutrient level of leaves of used phosphorite powder activated were greater than used superphosphate and calcium magnesium phosphate at apiece procreate period in Cirtus grandis cv.Shatianyou,and so that the character of agriculture were acquited preferably and the yield were higher as well as the quality were not influenced.The research result showed,The fruit tree could are used direct and annually cheap phosphorite powder,the fertilizer effect of phosphorite powder that were used activating technique exceed superphosphate and calcium magnesium phosphate,thereby the cost of fertilizer and fertilization service were reduced,and waste and environmental pollution were decreased because of fertilization excessive.
