| 摘 要： | 【目的】研究新疆南疆全立架露地栽培甜瓜的平衡施肥参数。【方法】进行两年多点的田间肥料缺素试验。【结果】施用化肥能使甜瓜产量提高21.55%～47.05%,氮肥、磷肥、钾肥全施处理的两年平均产量为71 591 kg/hm~2,较对照(不施肥)增加47.05%,化肥对甜瓜产量的贡献大小顺序为氮肥>钾肥≥磷肥。全立架露地栽培甜瓜的养分吸收系数分别为:N 207.0g/100 kg、P_2O_5 43.1g/100 kg、K_2O 536.6 g/100 kg(N:P_2O_5:K_2O为1:0.21:2.59)。研究区土壤有效养分与有效养分校正系数之间呈负相关关系,土壤有效养分校正系数分别为:碱解氮1.87 kg~2/(mg·hm~2)、速效磷1.02 kg~2/(mg·hm~2)、速效钾1.30 kg~2/(mg·hm~2)。肥料当季利用率分别为:氮肥26.2%、磷肥3.7%、钾肥47.8%。【结论】当全立架露地栽培甜瓜的目标产量为75000 kg/hm~2时,氮、磷、钾肥的施用量分别为:N 310.04 kg/hm~2、P_2O_5 135.44 kg/hm~2、K_2O 154.35 kg/hm~2。

| Abstract: | Objective]The purpose of this project was to study the balanced fertilization parameters of trellis - cultivated melon.Method]Two years' field experiment from 2010 to 2011 were conducted. Result]The results showed that the melon yields are increased from 21.55%to 47.05%under the different fertilization,and the order of increasing rates by the elements is N>K≥P.The amount of N,P_2O_5,K_2O absorbance by 100 kg melon is 207.0,43.1 and 536.6 g accordingly.The ratio of N:P_2O_5:K_2O is 1:0.21: 2.59.A negative correlation between soil available nutrients and nutrient rectified coefficient of the soil,and the utilization coefficient of nitrogen,phosphorus and potassium are 1.87,1.02 and 1.30 kg~2/mg ? hm~2.The utilization rate of nitrogen,phosphorus and potassium fertilizer are 26.2%,3.7%and 47.8%. Conclusion]When the target of trellis - cultivated melon yield is 75 000 kg/hm~2,the fertilization combination is N 310.04 kg/hm~2,P_2O_5 135.44 kg/hm~2 and K_2O 154.35 kg/hm~2. |
