摘要
在磷钾肥同等施入条件下,采用随机区组法,研究施入纯氮量193.5 kg、178.5 kg、164.3 kg、149.1 kg、133.8 kg/hm^(2),对水稻新品种松辽677产量的影响。试验结果表明:施纯氮肥193.5 kg/hm^(2)产量最高9325.5 kg/hm^(2),比CK平均产量8142.5 kg/hm^(2),增产1182.5 kg/hm^(2),增产14.52%,达到极显著水平。
The effects of 193.5 kg,178.5 kg,164.3 kg,149.1 kg and 133.8 kg/hm^(2)of pure nitrogen on the yield of new rice variety Songliao-677 were studied by random block method under the same application conditions of phosphorus and potassium.The results showed that the maximum yield was 9325.5 kg/hm^(2)under the condition of 193.5 kg/hm^(2)of pure nitrogen.The yield was increased by 1182.5 kg/hm^(2)than CK and reached a very significant level.
