以尿素和硫酸钾为主要氮、钾肥料,以草炭和蛭石为育苗基质进行番茄育苗试验,研究分析了育苗基质中不同氮、钾肥料配施方案对番茄幼苗生长及其前期产量构成的影响,结果表明:番茄育苗过程中氮、钾肥料不同配比对番茄幼苗生长及前期产量存在显著影响,偏施氮肥或钾肥均可降低番茄出苗率、抑制番茄幼苗生长与干物质积累,氮、钾肥料合理配施可明显提高番茄幼苗素质,增加番茄前期开花数与座果数从而增加番茄前期产量,番茄基质育苗过程中氮、钾(N∶K2O)肥料最佳配比为1∶1.2。
Taking urea and potassium sulfate as the main nitrogen and potassium fertilizers, peat and vermiculite were used as substrate for nurturing tomato. The effects of different nitrogen and potassium fertilizers on the growth of tomato seedlings and their early yield components were studied. The results showed that different proportions of nitrogen and potassium fertilizers had significant effects on the growth and early yield of tomato seedlings. Partial or total nitrogen and potassium fertilizer could reduce the emergence rate of tomato seedlings, inhibit the growth of tomato seedlings and the accumulation of dry matter, Fertilizer reasonable allocation can significantly improve the quality of tomato seedlings, increase the number of pre-flowering tomato and fruit set to increase pre-production of tomato, tomato substrate nursery process nitrogen, potassium (N: K2O) fertilizer best ratio of 1: 1.2.
