| 摘 要： | 为了获取在水分优化管理条件下合理的氮肥施用量,研究了冬、春茬和秋、冬茬日光温室黄瓜生产中不同施氮量对黄瓜产量及品质的影响。以农民经验水氮管理为对照,冬、春茬为N 840 kg/hm2+水450m3/(hm2.次),秋、冬茬为N 465 kg/hm2+水450 m3/(hm2.次)(I1N1);在优化水分管理条件下300 m3/(hm2.次),设计了3个施氮水平,冬、春茬分别为N 840 kg/hm2(I2N1)、N 240 kg/hm2(I2N2)和N0(I2N3);秋、冬茬分别为N 465 kg/hm2(I2N1)、N 50 kg/hm2(I2N2)和N0(I2N3)。结果表明:冬、春茬的I2N2组合的产量比I2N1I、2N3的产量分别高12.9%、41.0%,与I1N1相比差异不显著;秋、冬茬I2N2组合的产量比I2N1高8.2%,与I1N1及I2N3处理相比,产量差异不显著。同时,I2N2组合提高了果实中VC及可溶性糖含量,降低了果实中硝酸盐,亚硝酸盐及单宁含量。综合冬、春茬和秋、冬茬试验中产量及品质2个因素,当灌水量为300 m3/(hm2.次)时,冬、春茬施氮量N 240 kg/hm2、秋、冬茬施氮量N 50 kg/hm2的I2N2能够获得最好栽培效果,水氮利用效率最高。

| Abstract: | In order to get the reasonable nitrogen utilization in the optimum water management,the paper studied that the effect of different nitrogen(N)and irrigation(I)combinations on yield and fruit quality.The experiential water and nitrogen(I1N1)treatment was as control,which were 840 kg/hm2 nitrogen and 450 m3/hm2 water per time in the winter-spring period,and 465 kg/hm2 nitrogen and 450 m3/hm2 water per time in the autumn winter period.Three treatments were design under the optimum water management condition(30... |
