摘　　要：研究了苗期不同追肥种类和追肥量对嘉定白蒜植株生长、蒜头产量和质量等方面的影响。结果表明 :提高追肥中的氮、钾比例 ,可促进大蒜植株健壮 ,显著提高蒜头产量和质量 ,明显提高经济效益。使用专用掺混肥 (BB肥 )增产效果优于普通复合肥和复混肥 ,最佳追肥方案为专用BB肥 4 0kg 6 6 6 .7m2 配合尿素4 .6kg 6 6 6 .7m2 ,N∶P2 O5∶K2 O为 10 .1∶4 .0∶8.0。The effects of kinds and amounts of top-dressing on the growth, yield and quality of Jiading garlic at seedling stage were studied. The results indicated that increasing the N and K contents of top-dressing could make garlic plants stronger, significantly improve the yield and quality of Jiading garlic, and therefore obviously enhance economic results. In addition, the effect of applying BB fertilizer on the yield increase was significantly better than that of applying ordinary complex fertilizer or mixed fertilizer. The optimum recipe for top-dressing was 40kg BB fertilizer per 666.7m 2 plus 4.6 kg urea per 666.7m 2, and N∶P 2O 5∶K 2O was equal to 10.1∶4.0∶8.0.
