采用田间试验,对强化栽培(SRI)和常规水作(TF)二种栽培方式以及氮肥用量对水稻产量、水分生产效率及稻田土壤氨挥发的影响进行了研究。结果表明,在不同施氮量条件下,强化栽培产量均高于常规水作,平均提高了24.1%。整个生育期强化栽培节约灌溉水830.3mm,提高了水分生产效率。不同施肥期两种栽培方式土壤氨挥发损失以基肥最高、分蘖肥次之,孕穗肥最低。强化栽培氨挥发损失总量平均提高25.2%。 Field experiments were conducted to study the effect of SRI and TF on the yield and water productivity of paddy rice and ammonia volatilization of paddy soil. The results showed that under different nitrogen rates, the yield of intensive cultivation was higher than that of conventional water, with an average increase of 24.1%. Intensified cultivation throughout the growing period to save irrigation water 830.3mm, improve water production efficiency. Different fertilization period of two cultivation methods of ammonia volatilization losses to the highest base fertilizer, tiller fertilizer times, the lowest booting spike. The average amount of ammonia volatilization loss in enhanced culture increased by 25.2% on average.
