| Abstract: |
| 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. |
