一、柘城县的土壤养分状况根据柘城县土壤肥料工作部门的化验结果表明我县土壤有机质平均含量15.18克/千克,有效磷平均含量为19.39毫克/千克,速效钾平均含量为116.2毫克/千克,全氮平均含量为1.07克/千克,PH值在7.9~8.2之间。从化验结果看柘城县耕地有机质、有效磷、全氮三项指标与第二次耕地普查结果相比有较大的幅度提高,而速效钾含量略有下降,PH值没有明显的变化,整体耕地地力达到了中高、水平。二、小麦的需肥规律小麦植株在一生中对氮磷钾的吸收总量、不
Soil Nutrient Status in Yuncheng According to the test results of Yuncheng Soil and Fertilizer Working Department, the average content of soil organic matter in our county is 15.18 g / kg, the average content of available phosphorus is 19.39 mg / kg, the average content of available potassium is 116.2 mg / Kg, the average total nitrogen content of 1.07 g / kg, PH value of 7.9 to 8.2 between. From the laboratory results, the three indicators of cultivated land organic matter, available phosphorus and total nitrogen in Tancheng County showed a greater increase compared with the results of the second arable land survey, but the available potassium content decreased slightly while the PH value did not change obviously. Cultivated land reached a high, level. Second, the law of wheat needs fertilizer Wheat plants in the life of total absorption of nitrogen, phosphorus and potassium, no
