摘要
不同比例的N、K配比、施用量及不同的施用时期,对香蕉的生长和产量都有不同的影响;N:K2O=1:2.25最有利香蕉的生长,花芽分化及孕蕾期前的肥料施用量占全年用量的70%左右的效果最好;N、K的肥料效应函数为Y=530.100+68.53x1-1.82x12+37.03x2-0.40x22+0.96x1x2,N、K的最佳配比函数为25.304-6.115x1+2.504x2=0。
Fertilizer ratios and fertilizer application during off season of banana as well as their effects were studied. Results showed that banana grew best at N:K2O=1:2.25. The best effect was achieved when about 70% fertilizer was applied before inflorescence. The function for N K fertilizer efficiency was Y=530.100+68.53x1-1.82x12+37.03x2-0.40x22+0.96x1x2. And the function for the best ratio was 25.304-6.115x,-2.504x2=0.
