在灰黄泥田上研究麸酸型有机复混肥对马铃薯产量、品质及养分累积吸收的影响。结果表明:与单施化肥相比,配施有机复混肥产量增幅达4.1%～18.7%,其中以100%麸酸型有机复混肥产量最高。另外,配施麸酸型有机复混肥还能增加马铃薯薯块的干物质重,提高灰份、粗蛋白以及氮、磷、钾含量,但对淀粉含量的影响不一。在经济效益方面,虽然配施麸酸型有机复混肥的马铃薯成本高于单施化肥,但经济效益总体优于施用单施化肥,每666.7m2较对照增加260.9~350.3元。
The effects of glutaric acid organic compound fertilizer on potato yield, quality and nutrient uptake and absorption were studied on gray and yellow soil. The results showed that the yield of organic compound fertilizer increased by 4.1% ~ 18.7% compared with that of single chemical fertilizer, and the yield of organic compound fertilizer with 100% of glutamic acid was the highest. In addition, with the addition of glutamic acid organic compound fertilizer can also increase the dry weight of potato tuber, increase ash, crude protein and nitrogen, phosphorus and potassium content, but the impact of different starch content. In terms of economic benefits, although the cost of potato with compound organic acid compound fertilizer is higher than that of chemical fertilizer alone, the economic benefit is better than that of chemical fertilizer alone, which increases by 260.9-350.3 yuan per 666.7m2.
