桑园种草养鸡对土壤养分含量变化的影响

Effects of Raising Chickens by Planting Grass on Soil Nutrient Content in Mulberry Field

为了探索桑园种草养鸡模式对土壤化学质量变化的影响,本研究通过分析种草养鸡3年桑园土壤养分含量的变化,探索桑园种草养鸡模式对土壤质量的影响。结果表明,受鸡群生理代谢的作用和影响,桑园种草养鸡后,增加了土壤中N、P、K和Mg元素的含量,桑园土壤存在着酸化的趋势,种草养鸡模式加速了桑园土壤的钙素退化。

In order to explore the effect of the model of grass-chicken in Mulberry garden on the change of soil chemical quality,this study analyzed the soil nutrient content of Mulberry field after three years,and explored the effect of the model of grass-chicken in Mulberry garden on the soil quality.The results showed that the content of N,P,K and Mg in soil increased under the effect of the physiological metabolism of chicken;Mulberry soil had a trend of acidification;and the degradation of calcium in mulberry field was accelerated by planting grass and raising chickens.
