摘要
2010～2011年采用调查分析的方法对千岛湖库区柑桔园78个样点0～40cm的土壤营养现状进行了取样分析,结果显示:58.97%土壤是pH值<4.8的偏酸性土,只有19.74%的土壤有机质含量丰富,90.79%土壤碱解氮、32.05%土壤速效磷、65.79%土壤速效钾等含量均呈极缺和缺乏状态,44.87%土壤速效磷、5.26%土壤速效钾等含量均呈超量状态,因此建议今后土壤管理应在合理施用有机肥料和改良土壤酸碱度的基础上,进行科学配方施肥,提高柑桔品质和产量,促进千岛湖库区柑桔产业的持续发展。
The soil nutrient status sampling analysis about 78 sample point from 0 to 40 cm on Citrus production in Qiandao lake reservoir area with investigation research method from 2010 to 2011. The results show that： 58.97% the soil pH value is 〈4.8 acidic soil, only 19.74% of the soil rich in organic matter, 90.79% soil alkali-hydrolyzable nitrogen, 32.05% of available phosphorus in soil, 65.79% soil available potassium content was very short and lack of state, 44.87% of available phosphorus in soil, 5.26% soil available potassium content showed excessive state, Therefore suggested that soil management should be in the rational application of organic fertilizer and soil pH value on the basis of scientific fertilization, improve the yield and quality of citrus, citrus, promote the industry sustainable development in Qiandao Lake area.
