Effects of Special Humic Acid Fertilizer on Brigitte Eggplant Growth

2005年9月至2006年10月,在辽宁普天科技有限公司试验基地温室安排了腐植酸茄子专用肥在布利塔茄子上不同用量试验。试验结果表明,施用腐植酸茄子专用肥能增加布利塔茄子产量,在本试验条件下比对照增产7.96%～14.97%,比化肥复合肥增产2.24%～8.72%,比津大复合肥增产0.35%～6.62%,增产效果显著。亩适宜施用量为50～60kg,能增加单叶重、叶片厚度、光合速率、叶绿素含量和基茎粗,提高株产量和株结果数,降低株病果数量,改善布利塔茄子品质。在经济收入上有所增加,亩施50kg专用肥,比对照增加收入13.89%。

From September 2005 to October 2006, the effect of different application rates of special humic acid fertilizer for eggplant on Brigitte eggplant growth was conducted in the greenhouse of Liaoning Putian Technology Co., Ltd..
