利用腐植酸物料抽提的腐植酸物质作为植物生长刺激素。法国Toulouse的国家聚合技术研究所根据SOFRECHIM开发的技术,用硝酸酸化木质纤维素渣料制得刺激素,并试验其作用和效果。经与现今市场上所销售的多种腐植酸抽提物相比具有明显的提高。如盆栽收获的干物质重量为对照的1.5倍,其根部生长以同样的比例增加,因此作物能较多地吸取养分,以磷素为例,吸取量为2倍。这种产品的起始有效用量是0.05％,在施肥较高的土壤中,可加强未利用的磷素移运。
The use of humic acid extraction of humic substances as plant growth hormone. According to the technology developed by SOFRECHIM, the National Institute of Polymerization Technology in Toulouse, France, used acidified lignocellulosic residues with nitric acid to produce stimulants and tested their effects and effects. Compared with the various humic acid extracts sold on the market today, there is a significant improvement. As the weight of dry matter harvested in pots is 1.5 times that of the control, its root growth increases in the same proportion, so the crop can absorb nutrients more. Take phosphorus as an example, the amount absorbed is 2 times. The starting effective amount of this product is 0.05%, which enhances the unused P transport in highly fertilized soils.
