不同施氮量对沙土地移动棚番茄生长与产量的影响研究结果表明：施纯N 360 kg/hm2时番茄产量最高,为5.87万kg/hm2,较不施氮肥的增产7890.0 kg/hm2,增产15.5%;施纯N 720 kg/hm2处理的番茄产量较低,为5.01万kg/hm2,主要是由于前期氮肥基肥用量随着尿素的增加,幼苗受害率加重,而导致缺苗、僵苗较重,影响了番茄的产量。

A study of the effect of different application rate of nitrogen fertilizer on the growth and yield of sand land mobile greenhouse tomato was conducted.The result showed that the yield was highest,namely 58,700 kg/hm2 when 360 kg/hm2 of pure nitrogen was applied,an increase of 15.5%,namely 7,890 kg/hm2 compared with that of the treatment without application of nitrogen fertilizer.The yield was relatively lower,namely 50,100 kg/hm2 when 720 kg/hm2 of pure nitrogen was applied.It was mainly due to the increase of the damage to young seedling along with the increase of nitrogen fertilizer dosage during early period and the seedling shortage and seedling death were serious and it produced an effect on the yield.
