| 摘 要： | 在含有不同氮磷钾养分的育苗基质(草炭∶蛭石=2V∶1V)中,进行番茄穴盘育苗。试验结果表明,基质中氮磷钾不同配比对番茄幼苗生长及质量的影响具有显著差异。在氮用量为500 g/m3、磷(P2O5)为1 000 g/m3、钾(K2O)为1 000 g/m3的育苗基质中,番茄幼苗茎粗、地下干重的增加明显加快,根系活力和根系吸收面积显著高于其它处理的幼苗。在本试验条件下,培育优质番茄穴盘苗的育苗基质中氮磷钾养分比例为N∶P2O5∶K2O=1∶2∶2,养分量为N 500 g/m3,P2O51 000 g/m3,K2O 1 000 g/m3。

| Abstract: | The effects on tomato seedling nursing of different nitrogen,phosphorus and potassium nutrients applied in nursing media with V(turf)∶V(vermiculite)=2∶1 were studied.The results showed that different ratios of nitrogen,phosphorus and potassium had significant effects on the growth and quality of tomato plug seedlings.The stem diameter and root dry weight of the tomato seedlings sowed in the substrates with 500 g/m~3 N,1 000 g/m~3 P,and 1 000 g/m~3 K increased rapidly,and root activity and root absorption area were significantly higher than that of other treatments.In this experiment,the optimum N,P and K scheme was N∶P_2O_5∶K_2O=1∶2∶2,that is,500 g/m~3(N,)1 000 g/m~3 P_2O_5 and 1 000 g/m~3 K_2O. |
