摘　　要：为探讨施肥及栽培密度对春小麦生物性状和产量的影响以及春小麦生产的适宜的密度与肥力,以优质强筋小麦龙麦33号和中筋小麦克旱21号为试验材料,设置了3个肥力水平和3个密度水平,分析了在不同的肥力和密度的共同处理下这2个小麦品种的生物性状和产量的变化。结果表明:不同氮肥和密度处理下,2个小麦品种在整个生育时期的生物性状总体变化无明显规律;克旱21号和龙麦33号在中等肥力、低密度(D2E1)处理下产量最高,分别为5 508.0和5 647.5kg/hm2;在不同氮肥处理下,低密度(E1)处理产量整体较高密度(E3)处理高;在不同密度下,中等肥力(D2)处理从整体上产量较低肥力(D1)和高肥力(D3)高,其他处理间无明显规律。In order to study the effects of fertilization and planting density on biological characters and yield of spring wheat, which provides a theoretical basis for high-yield cultivation techniques of spring wheat, this experi- ment use high quality and strong gluten wheat Longmai 33 and medium gluten wheat Kehan21 as the experimental material, setting up 3 fertility level and density of the 3 level, and analyses changes of the two varieties on biological characters and yield under the different treatments of fertility and density.The results showed that ： under different Nitrogen and density treatments, two varieties had no obvious regularity on the biological characters in the whole growth period of wheat overall; under the middle fertility and low density （D2E 1 ）treatment, Kehan 21 and Longmai 33 had the highest yield, which were 5 508.0 and 5 647.Skg/hm2; in the different fertilizer treatments, low density （El） treatment was overall higherthan the high ones （E3）on the yield;under the different density treatments, the yield of the moderate fertility （D2）treatment from the overall was higher than the low ones （D 1 ）and high ones （D3） ; no obvious regularity existed between other treatments.
