| 摘 要： | 以农院45号为材料，研究了土壤水分与施N量对水稻生长发育和产量的影响，结果表明：水分与氮肥之间有一定的互作效应，节水灌溉(轻度水分胁迫)结合适量的氮肥在节水的基础上不降低产量，在生产上可行。在土壤干旱严重时和良好的水层条件下都不宜过多施用氮肥，否则，一方面会增加生产成本，另一方面可能会造成氮肥的浪费和污染。

| Abstract: | A model plant Nongyuan No.45 was taken to study the effects of soil moisture and nitrogen on the growth and output of paddy rice.Results showed that there was interaction between moisture and nitrogen fertilizer,water-saving irrigation(lower water stress)with the combination of moderate nitrogen fertilizer does not decrease the yield of rice,and feasible in production.Nitrogen fertilizer can not be over-utilized in sorious arid period and good water layer.On one hand,it can increase the cost of production,and may cause nitrogen fertilizer waste and pollution. |
