本试验采用池栽、田间试验等手段,对筛选出的几种花生氮、磷、钾最佳配比进行了肥效鉴定。结果表明,大田条件下,覆膜种植以N_3P_3K_6(公斤/亩)表现较好;露地栽培以N_3P_3K_6和N_3P_(1.5)K_9较好,与高产施肥措施相比,每亩增收118.7～141.32元。试验中还对处理间农艺性状进行了比较,并对植株中氮、磷、钾吸收量、叶绿素含量和光合强度等进行了测定分析。
In this experiment, we planted the best proportion of nitrogen, phosphorus and potassium in selected peanut by means of pool planting and field experiment. The results showed that the film mulching performed better with N_3P_3K_6 (kg / acre) under field conditions. The N_3P_3K_6 and N_3P_ (1.5) K_9 were better in open field cultivation, with an increase of 118.7 ~ 141.32 yuan per mu compared with high yield fertilization. In the experiment, the agronomic traits among the treatments were also compared. The contents of nitrogen, phosphorus and potassium uptake, chlorophyll content and photosynthetic rate in the plants were measured and analyzed.
