采用盆钵模拟试验,研究了两种解磷剂对种植小麦的石灰性土壤中磷的影响,结果表明:通过干湿交替情况来加速土壤熟化,再测定不同时期土壤中有机磷和速效磷的含量,经过分析得出有机磷与速效磷成显著的负相关,即腐殖酸解磷剂能促进有机磷向速效磷转化,并明显提高速效磷的含量,各处理腐殖酸解磷剂均优于或约等于无机解磷剂,且腐殖酸解磷剂中以100:1处理的效果最好,无机解磷剂对土壤磷的作用不明显。
The pot experiment was conducted to study the effect of two phosphate-solubilizing agents on phosphorus in the calcareous soils of wheat growing. The results showed that the soil ripening was accelerated by alternation of wet and dry conditions, and then the content of organic phosphorus and available phosphorus Content, after analysis, it was found that there was a significant negative correlation between organic phosphorus and available phosphorus, that is, humic acid phosphorous-dissolving agent can promote the conversion of organic phosphorus to available phosphorus and significantly increase the content of available phosphorus. Is better than or about equal to that of inorganic phosphate, and the effect of 100: 1 treatment is the best in humic acid phosphate solution and the effect of inorganic phosphate on soil phosphorus is not obvious.
