河北省农村历来主要依靠有机肥料解决农业用肥。各地群众对积漚和保存有机肥料都有很丰富的經驗。但各地积漚的肥料质量差異很大。根据历年我們对各地积攒的肥料所进行的分析鉴定資料,冀北山区及冀东地区的农家肥料平均含氮0.286%(28个样品),磷0.411%(23个样品),鉀0.746%(21个样品),灰分69.89%(4个样品),其中含氮量低于0.3%的样品占60.7%。冀中南平原地区的农家肥料含氮0.252%(50个样品),磷0.318%(22个样品),鉀0.851%(20个
Hebei Province has always been mainly rely on organic fertilizer to solve agricultural fertilizer. People from all over the country have accumulated rich experience in preserving organic fertilizers. However, the quality of fertilizers varies widely across the plot. According to the analysis and appraisal data of fertilizers accumulated over the years, the average nitrogen content in farmlands in northern Hebei and eastern Hebei was 0.286% (28 samples), 0.411% (23 samples), 0.746% (21%) potassium ), 69.89% (4 samples) of ash, of which samples containing less than 0.3% nitrogen accounted for 60.7%. The peasant fertilizer in the central-southern Hebei Plain contains 0.252% nitrogen (50 samples), 0.318% phosphorus (22 samples), 0.851% potassium (20
