采用氮磷比例试验和用量试验设计在同一试验中进行的方法,对烟草最佳施肥比例和最大施肥量进行了研究。结果表明,氮磷钾施肥比例是影响烟叶品质和产量的重要因素,试验土壤养分条件下种植烟草,最佳氮磷钾施用比例为1:1.5:1,氮磷钾施用比例对烟草品质的影响大于氮磷钾施用量的影响,而氮磷钾施用量对品质的影响大于对产量的影响。
Nitrogen and phosphorus ratio test and dosage test design in the same test method, the optimal proportion of tobacco and fertilization were studied. The results showed that the proportion of N, P, K fertilizers was an important factor affecting the quality and yield of tobacco leaves. The optimal proportion of N, P and K was 1: 1.5: 1 when tobacco was planted under soil nutrient conditions. The influence of N, P, K fertilizers on tobacco quality Which is greater than that of NPK. However, the effects of N, P and K fertilization on quality are greater than those of NPK.
