摘　　要：为验证多肽有机氮肥对作物的生长与增产影响,以大白菜为试验作物,在湖北省利川市二高山区域进行田间试验。结果表明,配施多肽有机氮肥比常规单施配方肥能显著提高大白菜的产量,667 m2增产600.9 kg、净增收232.9元、增幅28.76%。该肥可促使大白菜根系发达,增强吸收养分的能力,继而实现增产增收。To verify the effect of polypeptide organic nitrogen fertilizer on crop growth and yield increase,a field experiment was carried out in the second alpine region of Lichuan,with Chinese cabbage as the test crop.The results showed that the combined application of polypeptide organic nitrogen fertilizer could significantly increase the yield of Chinese cabbage compared with the conventional single application of formula fertilizer.The yield increased by 600.9 kg per 667 m2,the net income increased by 232.9 yuan,and the increase rate was 28.76%.The fertilizer could promote the development of Chinese cabbage roots,enhance the ability to absorb nutrients,and achieve increased production and income.
