摘要
为获得水稻、香蕉、番茄适宜的用氮量与氮磷钾配方,应用不同配方的BB肥添加氮、钾成分组成配方组合.对3种作物进行肥效与配方鉴比试验。结果表明,在速效钾含量比较丰富的水稻土,水稻以每公顷用氮(N)142 kg·N:P2O5:K2O=1:0.54:0.58为佳;在速效钾含量丰富的灰泥田,对耗钾量大的香蕉,以每公顷用氮459 kg,N:P2O5:K2O=1:0.50:2.45为佳;在速效钾含量缺乏的灰埭田,番茄以每公顷用氮504 kg,N:P2O5:K2O=1:0.47:2.72为佳。
A field experiment with different proportion of BB fertilizer and other fertilizer forms was carried out to study the optimal formula of N, P and K for rice, banana, and tomato. The results showed that on the paddy soils rich in available K, the optimal N rate and the optimal N : P2O5 : K2O formula were 142 kg · hm-2 and 1: 0. 54 : 0. 58 for rice, 459 kg · hm-2 and 1: 0. 50 : 2. 45 for banana that requires large amount of K, on the coastal saline soil which were poor in available K, 504 kg N · hm-2 and a N : P2O5 : K2O formula of 1 : 0. 47 : 2. 72 were recommended for tomato.
