夏红薯施用惠满丰有机复混肥 3 0 0 ,6 0 0 ,90 0kg/hm2 后 ,较不施肥对照增产鲜薯 41 83 .5～ 6 5 1 6 .0kg/hm2 ,增产幅度 2 4 .8%～ 3 8.6 % ,平均 3 1 .8%。与施用化肥相比 ,增产鲜薯1 71 6 .0～ 40 4 8.5kg/hm2 ,增幅 8.9%～ 2 0 .9% ,增产效果极为显著。在本试验条件下 ,无论等养分量与否 ,惠满丰有机复混肥均较化肥增产效果显著 ,从增产及效益等方面综合评估 ,惠满丰有机复混肥的适宜施用量是 6 0 0kg/hm2 左右。
Xia sweet potato Xiamai Feng organic compound fertilizer after 300, 600, 90 0kg / hm2, compared with no fertilization control yield 41 83 .5 ~ 6 5 1 6 .0kg / hm2, yield 24. 8% ~ 3 8.6%, with an average of 31.8%. Compared with the application of chemical fertilizers, the yield of fresh potato 1 71.06 ~ 40 4 8.5kg / hm2, an increase of 8.9% ~ 20.9%, the yield is extremely significant. Under the test conditions, regardless of whether the amount of nutrients or not, Hui Man Fung organic compound fertilizer significantly higher than the yield of fertilizer, comprehensive assessment from the aspects of yield and benefits, Hui Man Fung organic compound fertilizer application rate is 60 0kg / hm2 or so.
