畜禽粪便生态肥对灌漠土肥力质量及人参果品质和效益的影响

在温室内进行了畜禽粪便生态肥对灌漠土肥力质量及人参果品质和效益影响的研究。结果表明:畜禽粪便生态肥适宜施肥量比例为畜禽有机肥45.00 t·hm^-2、人参果专用肥1.50 t·hm^-2、聚丙烯酰胺0.09 t·hm^-2;施用畜禽粪便生态肥与传统化肥比较,土壤容重和pH值降低5.39%和9.11%,总孔隙度、团聚体、CEC、饱和持水量增加5.18%、21.03%、22.40%和5.18%,有机质、碱解氮、速效磷和速效钾增加20.36%、2.04%、2.01%和2.04%;细菌、放线菌、蔗糖酶活性、脲酶活性、磷酸酶活性和多酚氧化酶活性增加10.53%、13.39%、13.74%、1.46%、5.41%和5.96%,人参果产量、可溶性糖、Vc和可溶性蛋白质增加5.45%、9.09%、7.55%和10.05%,施肥利润和肥料投资效率增加30.31%和33.52%,硝酸盐降低7.78%。施用畜禽粪便生态肥改善了灌漠土质量和人参果品质,提高了土壤有机质和人参果经济效益。

Effects of livestock manure ecological fertilizer on fertility of irrigated desert soil and ginseng fruit quality and benefit

In the greenhouse, a field experiment was carried out to study the effects of ecological manure of livestock and poultry on soil fertility and ginseng fruit quality and benefit. The results showed that the suitable fertilizer proportion of animal manure ecological fertilizer was 45.00, 1.50, 0.09 t·hm^-2 of polyacrylamide. Compared with traditional chemical fertilizer, the soil bulk density and pH value decreased by 5.39% and 9.11%, and the total porosity, aggregate, CEC and saturated water capacity increased by 5.18%, 21.03%, 22.40% and 5.18%. Organic matter, alkali\|hydrolyzed nitrogen, available phosphorus and available potassium increased by 20.36%, 2.04%, 2.01% and 2.04%, while the activities of bacteria, actinomyces, sucrase, urease, phosphatase and polyphenol oxidase increased by 10.53%, 13.39%, 13.74%, 1.46%, 5.41% and 5.96%. Ginseng fruit yield, soluble sugar, Vc and soluble protein increased by 5.45%, 9.09%, 7.55% and 10.05%, fertilizer profit and fertilizer investment efficiency increased by 30.31% and 33.52%, nitrate decreased by 7.78%. The application of livestock and poultry manure ecological fertilizer improved the quality of soil and ginseng fruit and the economic benefits of soil organic matter and ginseng fruit.
