以不施肥为对照,研究了不同施肥量和施肥配比对小麦产量及产量构成因素的影响,结果表明:随氮、磷用量的增加,有效分蘖、穗粒数、千粒重和产量也增加,最高产量8 800.5 kg/hm2,出现在高产田的高肥处理中;最低产量4 885.5 kg/hm2,出现在中产田的不施肥处理中。因此,施纯N 270 kg/hm2、P2O5 135 kg/hm2是喀什地区高、中产田理想的施肥配比。
The effects of different fertilization rates and fertilization rates on the yield and yield components of wheat were studied. The results showed that the effective tillers, the number of grains per spike, the 1000-grain weight and yield increased with the increase of nitrogen and phosphorus levels, the highest The yield was 8 800.5 kg / hm2, which appeared in the high-fat treatment of high-yielding field. The minimum yield was 4885.5 kg / hm2, which appeared in the non-fertilization of middle-yielding field. Therefore, Shi Chun N 270 kg / hm2, P2O5 135 kg / hm2 is Kashgar region, middle-yield ideal fertilization ratio.
