采用小区试验,探讨撒可富复合肥15-20-10(含氯级)、洋丰大豆肥12-25-8(含氯级)、洋丰大豆肥12-23-10(K2SO4型)和鲁西大豆肥12-20-13(K2SO4型)与常规施肥的比较试验,目的是筛选出更好的复合肥来指导农业生产。结果表明:在今年的气候条件下,含氯级的撒可富复合肥15-20-10,亩产量和亩增效益均是最大,分别是225.1kg和68.35元,较对照增产10.9%,其次是含氯级的洋丰大豆肥12-25-8,亩产量和亩增产效益分别是220.0kg和45.15元,较对照增产8.4%;而含硫级的复合肥洋丰大豆肥12-23-10和鲁西大豆肥12-20-13,亩产量分别是183.7公斤和175.4公斤,较对照分别减产9.5%和13.6%,均是负效益。
The plot test was conducted to investigate the effects of 15-20-10 (Chlorine grade), 22-25-8 (Chlorine grade) of Yangfeng soybean fertilizer, 12-23-10 (K2SO4 type) of Yangfeng soybean fertilizer and Luxi soybean fertilizer 12-20-13 (K2SO4-type) and conventional fertilization comparison test, the purpose is to filter out better fertilizer to guide agricultural production. The results showed that under the climatic conditions of this year, the chlorine-containing sakofu compound fertilizer had the highest yield of 15-20-10, the yield per mu and the benefit per acre increased by 225.1kg and 68.35 yuan respectively, 10.9% more than the control, followed by Is chlorine-grade Yangfeng soybean fertilizer 12-25-8, yield per mu and yield increase of 220.0kg and 45.15 yuan, respectively, compared with the control yield 8.4%; and the sulfur-containing fertilizer Yangfeng soybean fertilizer 12-23- 10 and Luxi soybean fertilizer 12-20-13, respectively. The yield per mu was 183.7 kg and 175.4 kg respectively, which were 9.5% and 13.6% lower than the control respectively, all of which were negative benefits.
