- 摘要:
- 试验以不同厂家生产的复合肥为试材,进行了与常规施肥为对照的试验。结果表明:12-18-15(K1SO4)处理,无论是大豆的生育性状,还是大豆的产量和经济效益,都明显地高于常规施肥和其它复合肥处理。以氮、磷肥投入为主的常规施肥,对提高大豆产量具有一定的局限性,减氮、稳磷、增钾可以明显地提高大豆的产量。硫酸钾复合肥12-18-15(K2SO4)与氯化钾复合肥15-15-15(KCl)相比,在总养分含量相等而钾素相同的条件下,含硫钾肥比含氯钾肥具有极明显的增产作用,增施硫肥可以大幅度地提高大豆的产量和经济效益。
- Abstract:
- Effect of Compound Fertilizers on Yield and Economic Benefit of SoybeanAbstract: Compared with routine fertilizer dressing,the compoud fertilizers from different facto-ries were tested. The result showed that 12-18-15 (K2S04 )treatment was significantly higherthan CK and other compound fertilizers in the characteristic of growth and devetopment, yieldand econome benefit. The CK mainly based on N and P205 input had certain limit to soybeanyield. However, reducing N holding PzOs and increasing K could improve the yield of soybean.On the condition of equal nutrient content and the same kalium compared with 15-15 -15 ( KCl)treatment 12-18-15 ( K2 S04 ) treatment could increase yield obviously. Increasing sulphureousferilizer could improve the yield of soybean and economic benefit.
