对包膜控释尿素的大棚黄瓜进行了田间试验,并对黄瓜的品质进行了测试分析。结果表明:控释尿素D90产量比对照增产67.6%;比普通尿素增产36.9%;D60虽比对照和普通尿素增产,但产量差异未达显著水平。对品质的影响主要表现在降低黄瓜果实硝酸盐含量、增加Vc含量和可溶性糖含量方面,以D90综合品质为最优,D60次之,普通尿素为最劣。综合各项,在黄瓜生产中以选用控释期为90天的包膜控释尿素为最好。
The greenhouse cucumber coated with controlled release urea was tested in field and the cucumber quality was tested and analyzed. The results showed that the yield of controlled release urea D90 increased 67.6% compared with that of control and increased 36.9% compared with that of common urea. The yield of D60 increased less than that of control and ordinary urea, but the difference was not significant. The main impact on the quality of cucumber fruit nitrate content, increase Vc content and soluble sugar content, the D90 overall quality as the best, D60 followed, the worst for ordinary urea. Comprehensive, the production of cucumber in the controlled release of 90 days for the controlled release coated urea as the best.
