将商品基质和蛭石按3∶1的体积比例混合后,通过在基质中一次性添加不同种类和浓度水平的N、P、K肥料,开展辣椒育苗施肥试验,以期筛选出最佳的施肥种类和肥料施用浓度。结果表明:添加N、NP、NK及NPK的处理能促进植株的生长,其中,NPK组合和NK组合效果更好;而单独施用K、P及PK组合会抑制植株的生长。以50%浓度水平的NPK组合为最佳施肥组合,有利于提高育苗质量。
After the commercial substrate and vermiculite were mixed in the volume ratio of 3:1, the pepper fertilization and fertilization experiment was carried out by adding different kinds and concentrations of N, P and K fertilizers into the matrix at one time, in order to select the best fertilization species And fertilizer application concentration. The results showed that the addition of N, NP, NK and NPK could promote the plant growth. Among them, NPK and NK combination were better. However, the combination of K, P and PK alone could inhibit the plant growth. The combination of NPK at the level of 50% is the best combination of fertilization, which is beneficial to improve the quality of nursery.
