摘  要:
在含有不同氮磷养分的育苗基质(草炭∶蛭石=2∶1)中,进行番茄穴盘育苗。试验结果表明:基质中氮磷养分对番茄幼苗生长及营养状况的影响具有显著差异,在高氮量中氮磷比例养分的基质中,番茄幼苗茎粗、地下干重的增加明显加快,同时促进了番茄幼苗对氮磷钾养分的吸收,提高了幼苗体内养分含量。在本试验条件下,培育优质番茄穴盘苗的育苗基质中氮磷养分比例为N∶P2O5=1∶2,养分量为N 500g.m-3,P2O51000g.m-3。

摘  要:
The effects of different nitrogen and phosphorus nutrients applied in nursery substrate on tomato plug seedlings sowed in the substrate(turf∶vermiculite=2∶1) was studied.The results showed that nitrogen and phosphorus nutrition had significant effects on the growth and nutrition of tomato plug seedlings.The stem diameter and root DW of seedlings increased rapidly sowed in the substrate with high amount of N and middle ratio of N and P,and the absorption of N,P,K and level of plant nutrition were promoted.In this experiment,the optimum N and P nutrition scheme was N∶P2O5=1∶2,N 500 g·m-3,P2O5 1000 g·m-3.
