摘要:
在陕西苹果主产区27个优质苹果基地县中的15个县，选取10年生左右的丰产果园采集48个土壤样品，测定了土壤中有机质、全N、全P、全K、速效养分及阳离子交换量的含量。分析结果表明，陕西苹果主产区丰产园土壤有机质含量相对较高，在调查的48户果园中，有机质含量≥1.0%的果园占96%；除宝塔和白水县的2个果园土壤全N含量偏低外，其余果园土壤全N含量较高，平均值为0.76 g/kg；土壤速效N含量＞50 mg/kg的果园仅占29%，含量较高，其余果园土壤中的速效N含量偏低；土壤全P全K含量丰富，速效P、速效K和阳离子交换量含量均达到绿色果品产地土壤肥力标准。第2期刘子龙等陕西苹果主产区丰产果园土壤养分状况的调查
Abstract:
Soil samples were collected from 15 of 27 apple base counties in major apple production areas of Shaanxi. The content were of soil organic matter, total N, total P, total K, available N,P,K and CEC, 48 orchards growing apple tree for about 10 years were chosed.The analysis showed that the soil organic matter content was high relatively in the highyiele orchards. In the 48 investigated apple orchards, the percentage of orchards with soil organic matter content more than 1.0% was 96%;the soil total N content was high relatively except Baota area and two apple orchards of Baishui county, the average content was 0.76 g/kg; the percentage of orchards with available N content more than 50 mg/kg was only 29%， the content was relatively low in the rest orchards; the total P and K contents were rich, the available N,P and CEC contents reached the standard of soil fertility of greenfruit production area.
