以往农民习惯在春耕前把积造的农家肥送到地里,顺着垄向扒成直径80～100厘米的小粪堆,待播种施用。一般驴吉普每车扒3～4堆,大马车或机动车扒5～6堆。这种顺垄扒小堆的方法,从保肥效角度看,既不科学,又不经济。农家肥送到地里执小堆与堆大堆,在保存肥效的能力上是不同的。有人做过试验,送粪前粪肥含矿解氮83PPm、有机质1.38％、速效钾550PPm,速效磷3.4PPm。送到地里30天后化验,扒小堆的矿解氮减少52％,有机 In the past peasants accustomed to the plot of farm produce before spring plowing sent to the ground, along the ridge into the diameter of 80 to 100 cm diameter dung heap, to be sowing application. General Donkey Jeep 3 to 4 cars per car heap, car or motor vehicle grilled 5-6 heap. This smooth furrow small heap method, from the perspective of fertilizer efficiency, neither science, nor economic. Manure sent to the ground to enforce the heap and piles piles, in the ability to save fertilizer is different. Some people have done tests, manure excrement before excrement containing nitrogen 83PPm, 1.38% organic matter, available potassium 550PPm, available phosphorus 3.4PPm. After being sent to the ground for testing in 30 days, the heap of small mines was reduced by 52% in terms of nitrogen and organic content
