褐煤基有机肥和土壤生态调理剂对姜田土壤养分及生姜生长的影响

Effects of Lignite Based Organic Fertilizer and Soil Ecological Conditioner on Ginger Soil Nutrients and Ginger Growth

为研究褐煤基有机肥及土壤生态调理剂对姜田土壤养分、生姜生长的影响,于山东省昌邑市开展了生姜种植试验。结果表明:与对照相比,施用褐煤基有机肥及土壤生态调理剂能改善土壤理化性质,显著提高土壤养分含量,其中土壤有机碳含量提高了1.2%~2.5%,钙含量增加了57.1%~185.7%,镁含量增加了0.3~6.3倍;病情指数显著降低,其中白绢病病情指数降低了15.4%~23.1%,根结线虫病情指数降低了7.7%~26.8%;生姜产量增加,单株姜重增加了0.8%~15.0%,公顷产量提高了5.9%~11.6%,增产效果显著。综合比较,以施用褐煤基有机肥7500 kg/hm^(2)+土壤生态调理剂375 L/hm^(2)效果最佳。

In order to study the effects of lignite based organic fertilizer and soil ecological conditioner on soil nutrients and ginger growth in ginger field,the ginger planting experiment was conducted in Changyi City of Shandong Province.The results showed that,the application of lignite based organic fertilizer and soil ecological conditioner could improve the soil physical and chemical properties and significantly increase soil nutrient content.Compared with the control,the soil organic carbon content increased by 1.2%-2.5%,the calcium content increased by 57.1%-185.7%,and the magnesium content increased by 0.3-6.3 times.Compared with the control,the disease index of each treatment decreased significantly,the disease index of southern blight decreased by 15.4%-23.1%,and the disease index of root knot nematode reduced by 7.7%-26.8%.Compared with the control,the ginger yield increased,the ginger weight per plant increased by 0.8%-15.0%,and the yield per hectare increased by 5.9%-11.6%,yield increase effect was significant.Comprehensive comparison showed that the application of lignite based organic fertilizer 7500 kg/hm^(2) +soil ecological conditioner 375 L/hm^(2) had the best yield increase effect.
