摘要
以"杭茄2010"茄子为试材,采用常规施肥和4个不同肥料用量(675、600、525、480kg·hm-2)的肥水同灌处理,分析了果实生长性状和养分含量,并统计其产量。结果表明:与常规施肥相比,采用肥水同灌的茄子单果质量、果实长度和横径分别增加了13.1%~35.1%、15.0%~43.8%、11.1%~33.3%,产量、产值和纯收益则分别增加了3.2%~8.5%、3.4%~9.9%、15.5%~26.5%。茄子氮磷钾含量在不同处理间没有显著性差异。综上,茄子追肥以675kg·hm-2(N∶P2O5∶K2O=16∶8∶34)的肥水同灌为宜。
‘Hang-eggplant 2010＇was taken as material.The conventional fertilization,and four integrated water and fertilizer irrigation treatments（fertilizing amount of 675,600,525,480 kg·hm-2）were set up to carry out the topdressing experiment of eggplants.The quality and yield of eggplant were studied.The results showed that in comparison with conventional fertilization,the fruit weight,length and diameter increased by 13.1%-35.1%,15.0%-43.8%,11.1%-33.3%in integrated water and fertilizer irrigation.The yield,production value and net income in integrated water and fertilizer irrigation treatments increased by 3.2%-8.5%,3.4%-9.9% and 15.5%-26.5%respectively,in comparison with conventional fertilization treatment.However,there were no significant differences in contents of fruit nitrogen,phosphate and potassium under different treatments.Among the five treatments,fertilizing amount of 675 kg· hm-2 was suitable for fertilization of eggplant.
