探索文山烤烟品种云烟87最佳氮磷钾比例,比较不同氮磷钾处理烤烟的生长和产质量表现。结果表明,3个处理的大田生育期天数均为133 d,处理间差异不显著;植物学性状、农艺性状、经济性状综合分析以T3处理(N∶P_2O_5∶K_2O为1∶1∶3)最佳,表现整齐度良好,田间生长势强,产量、产值最高,667 m~2分别为114 kg和2 966元,且与T1、T2处理间差异显著。
Explore the best ratio of N, P, K in Fanyan 87, and compare the growth, yield and quality of flue-cured tobacco treated with different NPK. The results showed that the days of growth of the three treatments were all 133 days and the difference between treatments was not significant. The comprehensive analysis of botanical, agronomic and economic characters was T3 (N: P2O5: K2O was 1: 1: 3) Good, the performance of good uniformity, strong growth in the field, yield, the highest output value, 667 m ~ 2 were 114 kg and 2966 yuan, and with T1, T2 significant difference between the treatment.
