设施条件下不同磷肥水平对茄子果实养分含量的影响

采用田间试验和室内化验相结合的方法,设置不同磷肥水平,研究了设施条件下不同磷肥水平对茄子果实养分含量的影响。结果表明:茄子果实中全氮、全磷、全钾、硝酸盐、亚硝酸盐含量表现为初果期盛果期收获期;通过各处理间茄子果实中养分含量的比较发现,除全钾含量各处理表现不显著外,其它指标均表现出减施磷肥20%的处理优于其它处理,其中全磷、全钾处理高于其它处理,硝酸盐、亚硝酸盐含量低于其它处理,说明减施磷肥20%的处理可以提高茄子果实的品质。

Effects of Different Phosphate Levels on Nutrient Content of Eggplant Fruits in Greenhouse

Effects of different phosphate levels on nutrient content of eggplant fruits in greenhouse were studied,with the adoption of field test and laboratory test by different phosphate levels.The content of eggplant fruit of nitrogen,phosphorus and potassium nitrate and nitrite of different period of reducing phosphorus process also compared.The results showed that the content of eggplant fruit of nitrogen,phosphorus and potassium nitrate and nitrite assumed early-days>full bearing age>harvest-time;After comparing the content of eggplant fruit,found that the treatment of minus 20% down was better than other treatment except for total potassium content with no significant performance,including total phosphorus,potassium was higher,nitrate and nitrite content was lower than other.It showed that the treatment of minus phosphatic fertilizer 20% could improve eggplant fruit quality.
