| 摘 要： | 通过田间试验,研究了配方施肥对苦瓜产量及品质的影响。结果表明,与缺氮处理相比,配方施肥处理施氮300 kg/hm2,苦瓜产量增加19.5 t/hm2,增产率为92.1%,每公斤氮素可使苦瓜增产65 kg;在速效磷、速效钾含量较高的地块施磷、钾肥对苦瓜产量作用不大;在配方施肥处理基础上,加施钼、硼、牛粪分别增产7.45%、3.69%和9.29%;与当地习惯施肥相比,可减少NPK养分87 kg/hm2,果实可溶糖含量相对增加40.6%,氮素农学利用率提高29.5%。

| Abstract: | A field trial was conducted to studied the influence of different fertilizer unit on yield and quality of balsam pear.The result indicated that,compare with PK experiment,the yield of formula fertilization could be raised 19.5 t/hm2 by increased the nitrogen using 300 kg/hm2,the growth rate reached 92.1%,the difference reached the remarkable level.That was to say it could be able to increase the yield of balsam pear 65 kg each 1 kg nitrogen raise.On the soil with high avail phosphorus and potassium content,increase the PK fertilizer would be useless for balsam pear's yield.In the NPK foundation,executes Mo,B and organic fertilizer could increase the yield by 7.45%,3.69% and 9.29%.Compared with the local custom fertilize,the formula fertilization could reduce the fertilizer(pure nutrient) quantity 87 kg/hm2,the soluble sugar of the fruits increase 40.6%,and increased the agronomic nitrogen use efficiency 29.5%. |
