| 摘 要： | 根据新乡市西部高产区及东南部中高产区10 683个土样化验结果,研究了新乡市农田分区的土壤养分状况,并比较了小麦测土配方施肥的经济效益。结果表明:西部地区各项养分指标明显高于东南部地区,其中,有机质高4.87 g/kg、全氮高0.30 g/kg、有效磷高6.66 mg/kg、速效钾高39.27 mg/kg,而严重缺磷及缺钾的地区较东部分别少4.56%和8.24%。依据土壤肥力对配方施肥量进行估算,结果显示,配方施肥较习惯施肥节约化肥施用总量33 577.55 t,节约施肥资金1.343亿元。 |

| Abstract: | Base on 10 683 soil samples collected from the high production areas in west Xinxiang and middle-high production areas in Southeast Xinxiang,the soil nutrient status was studied,and the economic benefit of formula fertilization by soil testing of wheat was analyzed.The results showed that the nutrient indexes in west were much higher than in southeast.The contents of organic matter,total nitrogen,available phosphorus and available potassium were higher in west.In phosphorus and potassium deficiency regions,the contents of phosphorus and potassium were 4.56% and 8.24% less than east.According to soil fertility,the formula fertilizer was estimated,which reduced 33 577.55 t than usual fertilization,and saved 1.343×10^8 Yuan of fertilization capital. |
