【摘要】 2006～2011年结合国家测土配方施肥项目,对获嘉县农田耕地土壤养分进行了普查。结果表明:依据全国第2次土壤普查的划分等级标准,获嘉县耕地土壤有机质、全氮、有效磷、速效钾、有效铜、有效锌、有效铁和有效锰平均含量均属于3级及以上水平;除速效钾略有降低外,其他养分含量均较第2次土壤普查值明显增加;土壤有机质、全氮、有效磷、速效钾等级为3级及以上的耕地分别占90.56%、96.87%、83.78%和79.21%。并提出在稳氮、控磷、控钾的基础上,要大力推广测土配方施肥技术;继续实行农作物秸秆还田技术,以培肥地力。更多还原

【Abstract】 The farmland soil nutrient status in Huojia County was surveyed based on the formula fertilization project by soil testing from 2006 to 2010.The results showed that the average contents of organic matter,total nitrogen,available P,K,Cu,Zn,Fe and Mn were at grade 3 or more.The content of available K decreased slightly,while the content of other nutrient increased obviously.The farmland with the contents of organic matter,total nitrogen,available P and K at grade 3 or more accounted for 90.56%,96.87%,83.78% and 79.21%,respectively.On the basis of stable N,controlled P and K,the formula fertilization technology by soil testing should be popularized greatly.The crops stalks returning to field technology should be used to fertilize the soil fertility.更多还原
