通过田间塑料薄膜隔离的试验方式,研究了氮、磷、钾肥料用量对水稻产量与品质的影响.结果表明,各种肥料处理产量较高的用量为:氮肥240 kg/hm~2(经济施肥量为160 kg/hm~2);磷肥(P_2O_5)150 g/hm~2;钾肥(K_2O)120 kg/hm~2.氮肥用量增加,可以显著提高产量、糙米率、长/宽比、胶稠度和蛋白质含量,降低垩白率、垩白度.磷肥用量增加,垩白率、垩白度明显降低,但是也会导致整精米率下降.钾肥用量增加虽然能使青米率下降,但是也会导致直链淀粉增加,从提高品质的角度看,各有利弊.氮肥是提高产量,改善品质的主要营养元素,提高产量和改善品质二者可以兼顾.

The effects of amount of nitrogen,phosphorus and potassium fertilizer application on yield and quantity of rice were studied in the paper by the method of plot isolated by plastic.The results showed that the high yield were obtained in treatments which amounts of three fertilizers application were as follows:240 kg/hm~2 of nitrogen(economical utilizing amount was 160 kg/hm~2),150 kg/hm~2 of phosphorus and 120 kg/hm~2 of potassium.If nitrogen fertilizer added,the yield,brown rice rate,length/width,gel consistency and protein increased and the chalky grain and chalkiness decreased.If phosphorus fertilizer added,the chalky grain and chalkiness decreased obviously,but the head rice rate decreased also.Although the green rice rate decreased when the potassium fertilizer added,whereas it caused the amylose content to increase.There were advantages and disadvantages from the point of view of quality.Nitrogen fertilizer was the important element to increase yield and improve quality.Increasing yield and improving quality may be achieved at the same time.
