【摘要】：對海南省三亞、樂東、陵水3個芒果主產(chǎn)區(qū)11個芒果種植園0~20 cm土層的土壤樣品進(jìn)行分析。結(jié)果表明,3個地區(qū)土壤的pH值均偏低,pH值5.5的土樣比例達(dá)到了90.91%,三亞、陵水pH值5.5的土樣達(dá)到了100%;全區(qū)有54.55%的土壤有機(jī)質(zhì)含量低于10 g/kg;36.36%的樣品堿解氮含量150 mg/kg,有效磷含量均高于10 mg/kg;81.82%的土壤速效鉀含量低于100 mg/kg�？傮w上看,陵水地區(qū)的有機(jī)質(zhì)、堿解氮、速效磷、速效鉀含量均低于三亞和樂東,而且3個地區(qū)的速效鉀含量均較低。
[Abstract]:Soil samples from 11 mango plantations in three main mango producing areas of Sanya, Ledong and Lingshui in Hainan Province were analyzed. The results showed that the proportion of soil samples with lower pH value and pH value reached 90.91 and Sanya, respectively. The soil samples with pH 5. 5 in Lingshui reached 100mg / kg; 54.55% samples with soil organic matter content less than 10 g / kg ~ (-1) 路kg ~ (-1) ~ (36. 36%) were less than 150mg / kg ~ (-1) N content, and the available phosphorus content was higher than 10 mg / kg ~ (-1) kg ~ (-1) K ~ (2 +) content of soil < 100 mg / kg ~ (-1). Generally speaking, the organic matter in Lingshui area was lower than 100 mg / kg 路kg ~ (-1) 路kg ~ (-1). The contents of alkali-hydrolyzed nitrogen, available phosphorus and available potassium were all lower than those in Sanya and Ledong, and the available K contents in the three regions were all lower.
