摘要
采集天水市麦积区、秦州区、秦安县和甘谷县具有代表性的108个苹果园0~40 cm耕层土壤样品,测定pH值、有机质含量和中微量元素有效含量。结果表明:麦积区、秦州区、秦安县、甘谷县苹果园土壤普遍偏碱性,pH值处在6.5~7.5的占比分别为0、3.2%、2.2%、10.5%;有机质含量普遍较低,有机质含量处于缺乏及以下水平的占比分别为84.6%、93.5%、71.1%、73.6%。4个县区苹果园土壤有效钙含量处于适宜及以上水平的占比均为100.0%;有效镁含量处于适宜及以上水平的占比均在90%以上,有效镁含量的空间变异显著;土壤有效铁含量处于适宜及以上水平的占比均在90%以上;土壤有效锰含量处于缺乏及以下水平的占比均在90%以上;麦积区苹果园土壤有效铜含量处于适宜及以上水平的占比为84.6%,其他3个县区苹果园土壤有效铜含量处于适宜及以上水平的占比均在90%以上;秦州区和秦安县苹果园土壤有效锌含量处于缺乏及以下水平的分别占比71.0%和66.7%;麦积区和秦安县果园土壤有效硼含量处于缺乏水平的分别占比69.2%和64.4%。因此,天水市4个县区均需重点关注苹果园土壤有效锰含量缺乏、偏碱和有机质含量偏低的问题。此外,秦州区还需重点关注土壤有效锌含量缺乏问题,麦积区需重点关注土壤有效硼含量缺乏问题,秦安县对土壤有效锌和有效硼含量缺乏问题均需重点关注。
Collect 108 soil samples from the 0-40 cm plough layer of representative apple orchards in Maiji District,Qinzhou District,Qin’an County and Gangu County of Tianshui City,and measure the pH value,organic matter content and available content of medium and trace elements.The results showed that:the apple orchard soil in Maiji District,Qinzhou District,Qin’an County and Gangu County was generally alkaline,and the proportions of pH values in the range of 6.5-7.5 were 0,3.2%,2.2%and 10.5%respectively;the organic matter content was generally low,and the proportions of organic matter content at the deficient and below levels were 84.6%,93.5%,71.1%and 73.6%respectively.The soil available calcium content of the apple orchards of the 4 counties and districts was at the suitable and above levels for 100.0%;the available magnesium content at the suitable and above levels was above 90%,and the spatial variation of the available magnesium content was significant;the available iron content in the soil at the suitable and above levels was above 90%;the soil available manganese content at the deficient and below levels was above 90%;the proportion of soil available copper content of the apple orchards in Maiji District at the suitable and above levels was 84.6%,and the soil proportions of available copper content in the apple orchards in the other 3 counties and districts at the suitable and above levels were all above 90%;the proportions of soil available zine content at the deficient and below levels in the apple orchards in Qinzhou District and Qin'an County were 71.0%and 66.7%respectively;the proportions of soil available boron content at the deficient levels in the orchards in Maiji District and Qin'an County were 69.2%and 64.4%respeetively.Therefore,all 4 counties and districts in Tianshui City need to focus on the problems of lack of available manganese content,alkalinity and low organic matter content in apple orchard soil.In addition,Qinzhou District needs to focus on the problem of lack of available zine content in the soil,Maiji District needs to focus on the problem of lack of available boron content in the soil,and Qin'an County needs to focus on the problems of lack of available zinc and available boron content in the soil.
