榆树县草炭资源丰富,分布较广,尤其在白浆土集中分布的东南部岗丘间的沟谷地,草炭的蕴藏量大,主要是低位草炭,质量好。作为临近坡耕地上白浆土的改土培肥材料,既便于就地取材,减少运输劳力,又可收到良好的改土效果。草炭是一种半腐烂的植物残体,富含有机质和氮索,有机质含量一般在50%左右,高者可达70~90%;腐殖酸含量多为20~40%;含氮量较高,多在1.O~2.5%之间;但磷、钾和速效氮含量较低。草炭具有强大的吸水性和吸氨性,每
Yushu County is rich in peat resources and has a wide distribution. Especially in the valleys between the hills in the southeastern part where albic soil is concentrated, the reserves of peat are large, mainly low peat and of good quality. As a slope near the sloping land of white soil soil fertility materials, both for easy local materials, reduce labor labor, but also receive good soil improvement effect. Peat is a semi-decaying plant residues, rich in organic matter and Nitrogen, organic matter content is generally about 50%, the highest up to 70 to 90%; humic acid content of mostly 20 to 40%; nitrogen content than High, mostly between 1.O ~ 2.5%; but phosphorus, potassium and available nitrogen content is low. Peat has a strong water absorption and ammonia absorption, each
