摘  要:
主要研究了01、003、005、00 kg.hm-24种氮素营养水平下,不同品种番茄生长发育以及产量的差异变化。在300 kg.hm-2的氮营养水平下,番茄叶霉病发病率最低,净光合速率、气孔导度均达最大值,产量最高;果实中硝酸盐含量随着施氮量的增加逐渐增高,糖酸比随施氮量的增加而降低。佳粉30和圣女在不同氮营养条件下的响应基本一致。

摘  要:
Studied the changes of growth and fruit yield of different tomato varieties under 0、100、300、500 kg/hm2 four kinds of nitrogen levels.Under the 300 kg/hm2 nitrogen level,the tomato leaf mold disease incidence rate was lowest,the photosynthetic rate、stomatal conductance of tomato has reached the maximum,the fruit yield was also the highest;When the nitrogen increased,the nitrate concentrates on fruits had gradually advanced,and the ratio of soluble sugar had reduced.Jiafen 30 and Shengnv had the consistent response under different nitrogen conditions.
