不同氮肥水平对茄子生长发育与产量的影响

Effects of Different Nitrogen Fertilizer Application Amounts on Growth and Yield of Eggplant

以苏崎3号为试验材料,设5个施氮水平,以不施氮为空白对照,常规施肥为对照,探究氮肥施用量对茄子生长发育和产量的影响。试验结果表明,茄子株高、茎粗、开展度、产量随氮肥用量增加先升高后降低,氮肥水平为20 kg/667 m2时茄子生长最旺盛,产量最高,达2239.18 kg/667 m2,因此,认为此氮肥水平为最佳施氮水平。

The effects of five nitrogen application amounts on the growth and yield of eggplant cultivar Suqi No.3 were studied,taking no fertilizer treatment and conventional fertilization treatment as blank control and control,respectively.The results showed that with the increase of nitrogen fertilizer concentration,the plant height,stem diameter,degree of development and yield of eggplant increased firstly and then decreased.The yield was the highest(2239.18 kg/667 m2)when the application amount of nitrogen fertilizer was 20 kg/667 m2,therefore,this nitrogen fertilizer application amount was optimum for Suqi No.3.
