摘要
砀山地区黄桃种植历史悠久,所产黄桃品质优良。通过对砀山县黄桃根系土中pH、有机质及有效态元素的相关性分析,阐明其元素之间的关系。结果显示,砀山县黄桃果园土壤偏碱性,且有机质含量水平相对较低;而pH与有机质、有效锌、碱解氮、速效钾、有效磷、有效铁间呈负相关关系;有机质则与有效锌、有效铜、速效钾、有效铁、有效磷呈正相关关系;有效锌、有效铜、速效钾两两之间存在正相关。因而改善砀山地区土壤酸碱度,增施有机肥,提高有机质含量,可以提高有效态元素的含量,进而提高黄桃产量及品质。
The yellow peach planting in the Dangshan area, Anhui has a long history, and the yellow peach produced here is of good quality. This paper carries out correlation analysis of pH value, organic matter and available elements in the root soil of yellow peach in the Dangshan area and makes an approach to the relationship between the elements. The results show that the soil in yellow peach orchards is alkaline with the relatively low organic matter content;there is a negative correlation between pH value and organic matter,available zinc, alkali hydrolyzable nitrogen, available potassium, available phosphorus, and available iron;there is a positive correlation between organic matter and available zinc, available copper, available potassium,available iron, and available phosphorus;there is a positive correlation between available zinc, available copper,and available potassium. Therefore, improving the soil pH value and increasing the use of organic fertilizers can increase the content of effective elements, thus, improve the yield and quality of yellow peaches.
