不同施钾量级对寒地水稻产量及稻米品质的影响

Effect of Different Amount of Potassium Application on the Yield and Quality of Rice in Cold Region

试验研究不同施钾量级对水稻干物质积累量、产量及稻米品质的影响,结果表明：当施钾量（K2O）为5.25 kg/667m^2时,水稻产量最高为635.6 kg/667 m^2;当施钾量为3.5 kg/667 m^2时,品质各项指标均较好,可以确定施钾量在3.5~5.25kg/667 m^2时产量及品质各项指标较好。

The effect of different amount of potassium application on the yield, amount of dry matter accumulation and quality were researched and the results indicated that the highest yield （635.6 kg/667 m^2） can achieve when the potassium was 5.25 kg/ 667 m^2, when the potassium was 3.5 kg/667 m^2, it can achieve better quality factors, so it can confirm that the optimal amount of potassium were 3.5-5.25 kg/667 m^2.
