化肥应用中出现的问题 ,并不是化肥本身所带来的 ,而是我国科学施肥水平不高造成的。据全国土壤普查结果表明 ,我国土壤施肥 ,m(N)∶ m(P2 O5)∶ m(K2 O)应为 1∶ 0 .5∶ 0 .4 ,而目前这一比例却为 1∶ 0 .4∶ 0 .17,出现施肥比例失衡。应遵循“六看”“三结合”的施肥原则。“
The problems that arise in the application of fertilizers are not caused by the fertilizer itself, but due to the low level of scientific fertilization in China. According to the national soil census results show that soil fertilization in China, m (N): m (P2 O5): m (K2 O) should be 1:0 .5: 0.4, but the current ratio is 1: 0. 4:17, there is an unbalanced fertilization rate. Should follow the “six see” “three combination” of the principle of fertilization. "
