新疆阿图什市木纳格葡萄土壤养分现状分析

为探明新疆阿图什市不同土壤质地、不同树龄木纳格葡萄园土壤养分及矿质元素的特性，笔者分别以壤土、粘土、沙土质地幼龄和盛果期果园为研究对象，分别测定0~20、20~60cm土样有机质、N、P、K、B、Fe、Zn、Mn、Cu等矿质元素含量，研究不同果园土壤养分和矿质元素的特性。结果表明：不同土壤质地大量元素有效磷、速效钾含量处于较高水平，速效氮含量处于偏低水平，粘土全氮含量处于较高水平，沙土、壤土全氮含量处于较低水平。微量元素有效硼、铜、铁含量处于较高水平，沙土锰含量、壤土锌含量处于低水平。阿图什市土壤有机质处于低水平，粘土中有机质、全氮、铜、铁、锰含量高于沙土和壤土，其中粘土中有机质、全氮、铁、锰与其他2种土壤质地含量差异极显著。从以上结果可以得出结论：新疆阿图什市葡萄园应增施有机肥，同时根据土壤质地、树龄等的不同，因地制宜，平衡施肥。

Analysis of Soil Nutrient in Root Zone of Munake Grape in Atux City of Xinjiang

In order to study the difference of soil nutrient elements distribution characteristic between different Munake Grape with various soil texture and tree age. Take full fruit and sapling period orchards respectively with loam, clay and sandy soil as research objects. Analyze for organic matters and nutrient elements (N, P, K, B, Fe,Zn,Mn,Cu) in 0-20 cm and 20-60 cm depths soil layer. The result showed that: the available phosphorus and available potassium contents were at a higher level, and the available nitrogen content was at a lower level in macronutrients of various soil texture. The total nitrogen of clay soil was at a higher level, The total nitrogen of loam and sandy soil were at a lower level. At the trace elements, effective boron ,Cu and Fe content were at a higher level, manganese element of sandy soil and zinc element of loam were at a lower level. The organic matter content was at the low level in Atux city. Clay had much higher organic matter, total nitrogen, copper, iron, manganese content than sandy soil and loam, The content of organic matter, total nitrogen, iron, manganese were extremely significant different between clay and sandy soil, loam . In general, vineyard soil in Atux city should be increased organ matter fertilization. And at the same time, we should adjust measures to local conditions, balanced fertilization according to different soil textured and tree age.
