| 摘 要： | 采用盆栽试验,探讨了连作花生土壤养分的变化及对施用有机肥料和无机肥料的反应。结果表明,中等肥力砂壤土多年不施肥连作花生,土壤中的速效钾含量每年以近10％的量递减,速效磷含量以连作第3年减少最多,达52.99％。连年施用有机肥料,可增加土壤中的有机质和氮素含量。多量施用N、P、K化肥,土壤中的速效磷,速效钾含量较施用有机肥料分别增加77.05％,23.53％。连作花生施用有机肥料和无机肥料,增产效果均低于轮作花生。

| Abstract: | The variation of nutrient in soil of sequential cropping peanut and the response of such soil to organic and chemical fertilizers were investigated through pot culture.The results showed that in sandyloams soil of sequential cropping of peanut without applying fertilizer for several years,the content of quick-acting potassium reduced by 10% every year.Quick-acting phosphorus content decreased most heavily in third year of sequential cropping by 52.99%.Application of organic fertilizer can increase organic nutrition and nitrogen content in the soil.The effectiveness of applying organic and chemical fertilizers in soil of sequential cropping peanut was lower than in the soil of rotating peanut. |
