摘要: 为比较史丹利含微量元素海藻液体肥(N:P:K=28:0:0,海藻提取液≥27%,铜≥0.02%,锌≥0.05%,锰≥0.05%,硼≥0.05%)、海藻液体肥(N:P:K=28:0:0,含海藻提取液≥27%)与普通液体肥(N:P:K=28:0:0)在小白菜上的施用效果,以‘上海青’小白菜为试材,研究了以上3 种肥料施用后对小白菜生长特性、产量和经济效益的影响。结果表明:施用含微量元素海藻液体肥小白菜的株高、根茎粗度均最高,收获时分别为23.5 cm和6.87 mm,比施用液体肥增加8.7%和16.9%;含微量元素海藻液体肥处理的小白菜理论产量为28505.1 kg/hm2,比液体肥和海藻液体肥处理的分别增产4711.3 kg/hm2和1244.5 kg/hm2,增产率分别达19.8%和4.6%。史丹利含微量元素海藻液体肥能促进白菜植株生长,显著提高产量,经济效益好。

Abstract: In order to compare the application effects of trace element seaweed liquid fertilizer (N:P:K=28:0:0, seaweed extract≥27%, Cu≥0.02%, Zn≥0.05%, Mn≥0.05%, B≥0.05%), seaweed liquid fertilizer (N:P:K=28:0:0,seaweed extract≥27% ) and liquid fertilizer (N:P:K=28:0:0) on Chinese cabbage of‘Shanghaiqing’, the growth characteristics, yield and economic benefit of these three kinds of fertilizers were studied. The results showed that the plant height and rhizome thickness of Chinese cabbage reached the highest under trace element seaweed liquid fertilizer treatment, which were 23.5 cm and 6.87 mm, respectively, and 8.7% and 16.9% higher than that of liquid fertilizer treatment. The theoretical yield of Chinese cabbage was 28505.1 kg/hm2 under trace element seaweed liquid fertilizer treatment, which was 4711.3 and 1244.5 kg/hm2 higher than that of liquid fertilizer treatment and seaweed liquid fertilizer treatment, respectively, yield growth rate were 19.8% and 4.6%, respectively. The trace element seaweed liquid fertilizer could promote the growth and improve the yield of Chinese cabbage significantly, and could obtain better economic returns.
