摘要:

为确定陕西榆林风沙草滩地区绿豆种植的最佳氮肥施用量,以‘榆绿1号’为试验对象,设计6个氮肥施用梯度,研究不同氮肥用量对绿豆植物学性状、经济性状和产量的影响。试验结果表明:不同氮肥用量对绿豆株高、主茎分枝数、百粒重和产量达到了差异显著的影响,对主茎节数、荚长、单株荚数和单荚粒数的影响差异不显著。由氮肥施用量和产量的回归方程得出,在施用P2O5 60 kg/hm2、K2O 45 kg/hm2和商品有机肥750 kg/hm2的基础上,氮肥最佳施用量推荐为75 kg/hm2

关键词: 绿豆, 氮肥, 农艺性状, 产量

Abstract:

To determine the best nitrogen fertilizing amount of mung bean in Yulin sandy area of Shaanxi Province, with mung bean varieties ‘Yulv No.1’ as the test material, 6 nitrogen application gradients were designed to study the effects of different nitrogen application amounts on mung bean botanical characters, economic characters and yield. The results showed that nitrogen application had a significant effect on plant height, branching number, 100-seed weight and yield of mung bean, and there was no significant difference in pods of branches, pod length, pods per plant and number of seeds per pod of mung bean. The regression equation of nitrogen application amount and yield showed that based on the application of P2O5 60 kg/hm2, K2O 45 kg/hm2 and commercial organic fertilizer 750 kg/hm2, the optimal N application amount was 75 kg/hm2.

Key words: mung bean, nitrogen fertilizer, agronomic characters, yield
