牡蛎壳土壤调理剂对黄泥田花生产量和土壤酸化改良的影响

为研究牡蛎壳土壤调理剂对黄泥田花生产量和土壤酸化改良的影响，通过在黄泥田种植的花生上分别施用牡蛎壳土壤调理剂2250 kg/hm2和1500 kg/hm2加常规施肥处理与不施用牡蛎壳土壤调理剂加常规施肥处理对比，以研究牡蛎壳土壤调理剂不同施用量对花生产量以及土壤酸化改良的效果。试验结果表明，施用不同量牡蛎壳土壤调理剂后花生产量分别增加16.8%和10.1%，纯收入分别增加1750.0元/hm2和900.0元/hm2，花生的各项农艺性状也得到提高。施用不同量牡蛎壳土壤调理剂后土壤的有机质、碱解氮、速效磷、速效钾含量均有明显提高，土壤pH分别提高了0.8和0.5。本研究结果为黄泥田花生增产和土壤酸化改良提供了实验依据。

Oyster Shell Soil Conditioner: Effects on Peanut Yield and Acidified Soil Amendment in Yellow Clayey Field

The paper aims to study the effects of oyster shell soil conditioner on peanut yield and acidified soil amendment in yellow clayey field. The author conducted comparison analysis of the application of oyster shell soil conditioner at the dosage of 2250 kg/hm2 and 1500 kg/hm2 respectively combined with normal fertilizer treatment on peanut grown in yellow clayey field and the application of conventional fertilizer treatment only, to investigate the efficacy of different dosages of oyster shell soil conditioner on peanut yield and acidified soil amendment. The results showed that: the yield of peanut increased by 16.8% and 10.1% respectively after the application of different dosages of oyster shell soil conditioner, and the net income increased by 1750.0 Yuan/hm2 and 900.0 Yuan/hm2, respectively; and the agronomic traits of peanut were also improved; the content of organic matter, alkali- hydrolyzed nitrogen, available phosphorus, available potassium and exchangeable calcium in yellow clayey soil were significantly increased after the application of different dosages of oyster shell soil conditioner, and the soil pH value was also increased by 0.8 and 0.5, respectively. The results provide experimental evidences for increasing peanut yield and improving acidified soil in yellow clayey field.
