摘要
为了解稻区土壤养分状况,并根据养分丰缺情况进行合理科学的施肥,最终实现水稻优质高产,对云南省新平县稻田土壤p H值、有机质、碱解氮、有效磷、速效钾、有效硫、有效镁、有效硼、有效锰、有效锌进行养分分析。结果表明,53.80%的土壤偏酸,23.40%的土壤有机质偏低,24.20%的土壤碱解氮缺乏,39.20%的土壤缺磷,65.80%的土壤缺钾,22.60%的土壤缺硫,7.87%的土壤缺镁,85.27%的土壤缺硼,14.04%的土壤缺锰,37.67%的土壤缺锌。水稻生产中应注意增施有机肥、钾肥,以培肥地力,补施硼肥,保持土壤养分平衡。
According to rice soil nutrient abundance and deficiency conditions,we carried out scientific and reasonable fertilization to rice to improve ultimately the quality and yield of rice,and then soil p H value,organic matter,Hydrolytic N,available P,available K,effective S,effective Mg,effective B,effective Mn,effective Zn of rice field in Xinping county of Yunnan province were analyzed. The result indicated that 53. 80 % soil was acidic,23. 40 % soil organic matter was lower,24. 20 % hydrolytic N,39. 20 % available P,65. 80 % available K,22. 60 % effective S,7. 87 % effective Mg,85. 27 % effective B,14. 04 % effective Mn and 37. 67 % effective Zn were deficient. So,we should pay attention to organic fertilizer,potash fertilizer in rice production to fertilize the soil fertility,supply boron,and maintain the balance of soil nutrients.
