【摘要】 采用供钾水平较低的赤砂土盆栽试验方法,在施用的硫酸钾镁肥基础上施用不同钾水平,研究钾、镁、硫元素对花生产量、品质及养分累积吸收的影响。结果表明:①KMgS 配比有利于花生生物产量、提高经济产量,较 K1MgS(低钾)配比的花生生物产量增产17.7 g/盆,增幅32.19%;其次为 K1MgS,较对照增产12.52 g/盆,增幅 22.77%,K2MgS(高钾)处理的花生生物产量较对照增产4.49 g/盆。增幅8.17%;②KMgS 处理的花生植株含氮、磷、镁量最高,较对照分别增幅26.30%、25.49%、36.27%;③花生植株含钾和硫量有随施钾施用量的增加而增加趋势。更多还原

【Abstract】 Effect of fertilization level of sulphate—potassium magnesium on yield,quality and nutrient ac- cumulation of peanut was studied by pot trial on red sandy soil of low K fertility.The results showed that: (1)KMgS beneficial to peanut production,improving an economic yield,compared with the control KMgS peanut ratio of biomass Yield 17.7 g/pots,or 32.19 percent;followed by K1MgS,compared with the con- trol yield 12.52 g/pots,or 22.77 percent;K2MgS deal with the output compared with the control output 4.49 g/pots,or 8.17 percent;(2)KMgS peanut plant content of nitrogen,phosphorus,magnesium is maximum volume,compared with the control KMgS,nitrogen,phosphorus,magnesium is Increase 26.30%,25.49%,36.27%;(3)Peanut plants potassium content and sulfur improving tendency of potas- sium magnesium sulfur fertilizer with a ratio.更多还原
