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柚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。
The results showed that the nutrient status of leaves of pomelo trees treated with activated phosphate rock was higher than that of superphosphate and Ca-Mg-P fertilizers Therefore, the agronomic traits performed well and the yield was high in each period. Supplementation of trace elements during the appropriate period could make high yield and quality of Shatian pomelo. The results show that fruit trees can be used directly and once a year to apply inexpensive phosphate rock, the use of activation technology allows phosphate fertilizer over calcium superphosphate and calcium magnesium phosphate fertilizer, which can significantly reduce the orchard fertilizers and fertilizers While reducing production costs, while reducing waste and environmental pollution caused by excessive fertilization and phosphate fertilizer production, but also make the utilization of paper waste product development and industrial waste as a resource to reduce its secondary pollution.
