Abstract:

Taking main processing tomato seedling of ‘Ligeer 87-5’ as test materials,the seeding had been irrigated 3 times by 25 kinds of treatment with different N∶P∶K mixture ratio by an orthogonal experimental design.After each watering,plant height,stem diameter,leaf area,fresh weight,chlorophyll content (SPAD value),aboveground fresh weight,dry weight and fresh weight,dry weight of underground part,and the dry weight of root cap ratio and strong seedling index were determined.The results showed that the plant height and fresh weight of seeding which sprayed by solution with N∶P∶K mixture ratio as 2.73∶2.73∶4.90 g per 2 kg water was extremely the highest after No.2;leaf area of seeding which sprayed by solution with N∶P∶K mixture ratio as 3.08∶0.91∶2,94 g per 2 kg water was extremely the highest.Processing tomato hole tray seedling nitrogen injection for the second time,namely 2～4 leaf stage,reasonable ratio of N∶P∶K could significantly increase the processing tomato hole tray seedling leaf area per plant,plant height and fresh weight,promote the nutrition growth.The plant SPAD of seeding which sprayed by solution with N∶P∶K mixture ratio as 2.36∶1.82∶1.47 g per 2 kg water was extremely the highest after three times spraying;leaf area of seeding which sprayed by solution with N∶P∶K mixture ratio as 3.08∶0.91∶2.94 g per 2 kg water was extremely the highest.Nitrogen had extremely significant effect on SPAD of processing tomato plug seedling and had significant effect on plant height and leaf area,the treatments had unsignificant effect on plant height,stem thick,above ground dry weight,root dry weight,total plant dry weight,dry weight of root cap ratio and strong seedling index of processing tomato plug seedling.
