控释复合肥对黄瓜产量及品质的影响

为了提高蔬菜生产中的养分管理水平，实现蔬菜生产的高产优质和可持续发展，采用田间试验研究控释复合肥对黄瓜产量、养分吸收及果实品质的影响。控释肥处理氮磷钾用量较常规施肥减少50%，其中20%的控释复合肥在育苗时与基质混合育苗，然后带肥移栽，其余80%控释肥采用条施的方式底施。结果表明：控释复合肥处理较常规育苗的黄瓜幼苗株高和叶片叶面积分别增加13%和12%。与常规施肥相比，施用控释复合肥的黄瓜产量提高14.1%，氮磷钾养分吸收量分别增加17.0%、11.1%和14.8%，硝酸盐含量降低11.9%。

Effects of Controlled Release Compound Fertilizer on Yield and Quality of Cucumber

In order to improve nutrient management of vegetable production, further achievement of high yield and good quality vegetable production as well as sustainable development. Field experiment was conducted to study the effects of controlled release compound fertilizers (CRFs) on yield, nutrition absorption and quality of cucumber. Compared to conventional fertilization strategy, NPK application rate of CRFs was reduced 50%, in which 20% was mixed with substratum when raised seedling and the other 80% was banding application when transplanted. Results showed that seedling height and leaf area with CRFs increased by 13% and 12% respectively in comparison to conventional fertilization, meanwhile, cucumber yield with CRFs increased 14.1%, N, P and K absorption increased by 17.0%, 11.1% and 14.8% respectively, nitrate content of cucumber decreased 11.9%.
