为了研究玉米地放养鹅对土壤有机质含量、p H值,玉米植株中粗蛋白、粗纤维含量及玉米籽实中重金属含量的影响,试验选取350只肉鹅放养于不施化肥和农药的玉米地中作为试验组,以施肥玉米地作为对照,待玉米老熟后对土壤有机质、土壤p H值、玉米植株和玉米籽实进行检测。结果表明:养鹅玉米地土壤中有机质含量均高于施肥玉米地,而土壤的p H值低于施肥玉米地,更接近于中性土壤;养鹅玉米地植株中粗蛋白和粗纤维含量均高于施肥玉米地;玉米籽实中重金属含量低于施肥玉米地。说明玉米地放养鹅模式有利于改善土壤肥力,降低土壤p H值,增加玉米植株中粗纤维和粗蛋白含量,降低玉米籽实中重金属含量。
In order to study the effect of stocking goose on soil organic matter content, p H value, crude protein, crude fiber content and heavy metal content in corn seedling, 350 geese were selected for experiment in maize field without fertilizers and pesticides As the experimental group, fertilize maize field was used as a control, and soil organic matter, soil p H value, corn plants and corn seeds were tested after the corn was cooked. The results showed that the soil organic matter content of goose maize was higher than that of fertilized maize, while the soil p H value was lower than that of fertilized maize and nearer to neutral soil. The contents of crude protein and crude fiber in goose maize Higher than that of fertilizing corn; the content of heavy metals in corn seed is lower than that of fertilizing corn. It shows that the mode of stocking geese in corn can improve soil fertility, reduce soil p H, increase the content of crude fiber and crude protein in corn plants, and reduce the content of heavy metals in corn seed.
