不同施肥模式对日光温室菜地渗透水氮·磷流失及黄瓜品质的影响
Effects of Fertilization Modes on Loss of Nitrogen and Phosphorus in Seepage Waters and Cucumber Quality
摘要
Abstract
[Objective] The research aimed to provide the theoretical basis for the proper regulation and control of water and fertilization as well as the harvest of the vegetables. [Method] The experiments under greenhouse conditions were conducted from August to November, 2010. During this period, samples of water and cucumbers were collected and analyzed in the laboratory. The effects of six different fertilization modes on the loss of nitrogen and phosphorus in seepage water and the quality of cucumbers planted were studied. [ Result ] Applying traditional fertilizers, the loss of nitrogen and phosphorus in the seepage water was 19.55,2.91 g/hm respectively, and the nitrate content in the cucumber reached up to 450.95 mg/kg. Compared to traditional fertilizers, the loss of nitrogen and phosphorus applied with special fertilizers with 20% and 40% decrement and organic fertilizers decreased 8.80 -12.27 and 1.74 - 2.37g/hm2, respectively. Meanwhile, compared to the control group, the content of VC and soluble sugar in cucumbers were both significantly increased by the later three fertilization modes. [ Conclusions] Special fertilizer and organic fertilizer should be adopted and advocated in future production of vegetables, whereas traditional fertilizer should try to be avoided.关键词
