摘要
通过田间小区试验,验证了在配方施肥的基础上增施惠农乐商品有机肥在甘蓝上的适宜用量及增产效果。试验结果表明,惠农乐商品有机肥667 m^2用量由50 kg提高到400 kg,甘蓝产量增加64.4~440.0 kg/667 m^2,增幅在3.41%~23.28%,667 m^2净增收13.9~55.5元;667 m^2用量在200 kg以上,甘蓝产量与对照差异达显著水平;用二次回归方程计算的最高产量施用量及最佳用量分别为820、264 kg/667 m^2;667 m^2增施100 kg该有机肥可替减20%的化肥。该有机肥对培肥地力及改良酸性土壤皆有一定效果,但短期内效果不显著,需长期坚持多年连续施用。
Through field plot experiment, the paper verified the suitable dosage and the yield-increasing effect of Huinongle commercial organic fertilizer on the basis of formulated fertilization. The results showed that, the yield of cabbage was increased by 64.4-440.0 kg/667 m^2 with the increasing rate of 3.41%-23.28%, and the net income was increased by13.9-55.5 Yuan/667 m^2, when the dosage of Huinongle commercial organic fertilizer was increased from 50 kg up to 400 kg.There was significant difference to the control treatment in cabbage yield when the dosage of Huinongle commercial organic fertilizer was upon 200 kg/667 m^2. According to the quadratic regression equation, the dosage which having highest yield and the appropriate dosage of Huinongle commercial organic fertilizer were 820, 264 kg/667 m^2, respectively.It could replace 20% chemical fertilizer by increasing 100 kg/667 m^2 Huinongle commercial organic fertilizer. This organic fertilizer had certain effects to improve soil fertility and acidity, but it did not having significant effect in a short time, so it must be continuously applied for years.
