摘要
为明确头花蓼获得高产的最佳施肥用量,进行了不同有机肥用量及尿素对头花蓼产量影响的试验,结果表明,667m2有机肥用量为2000 kg时,可获得最佳产量1856.9 kg。施用有机肥可明显提高头花蓼的第二季产量,随着有机肥施用量的增加,头花蓼的折干率逐渐降低。
The test was conducted to investigate the effect of different amount of organic fertilizer and urea on yield of Polygonum capitatum and to find the optimum organic fertilizer amount for getting the optimal yield of Polygonum capitatum. The results showed that the optimal fresh yield could be up to 1856.9 kg/667m^2 when 2000 kg/667m^2 of organic fertilizer was applied, that applying organic fertilizer could obviously increase the Polygonum capitatum yield in the next season and the dry material content of Polygonum capitatum gradually decreased with increase of organic fertilizer.
