控释BB肥在4种作物上的对比试验表明,控释BB肥在水稻、慈姑上效果明显,产量、产值均高于对照;在马铃薯上则产量低于对照,但品质好,产值高于对照;在甘蓝上产量、产值均比对照低,因此,建议在水稻、慈姑、马铃薯上推广使用。 Controlled-release BB fertilizer on four crops showed that the controlled-release BB fertilizer had obvious effects on rice and arrowhead, the yield and the output value were all higher than the control; the yield on the potato was lower than the control, but the quality was good and the output value was higher than Control; in cabbage production, output value is lower than the control, therefore, it is recommended in rice, arrowhead, potato promotion use.
