前言 泥炭富含有机质,其有机质主要由未分解完全的植物残体和腐植酸组成。用泥炭制作营养土,对于改善土壤的通气状况,提高供氧水平和促进根系吸收能力有良好的作用;泥炭中腐植酸对土壤养分转化,促进作物对营养物质的吸收,对植株的呼吸和酶的活性有良好的影响。用泥炭配制的营养土具有容重小、质地疏松、保水保肥性好,pH值适宜等优点。我省有较丰富的泥炭资源,
Preface Peat is rich in organic matter and its organic matter consists mainly of unresolved plant residues and humic acids. The use of peat to make nutritious soil has a good effect on improving the ventilation condition of the soil, increasing the level of oxygen supply and promoting root absorption capacity; humic acid in peat transforms soil nutrients, promotes the absorption of nutrients by plants, and respiration and enzymes of plants The activity has a good influence. The nutrient soil prepared with peat has the advantages of small bulk density, loose texture, good water retention and fertilizer retention, and suitable pH value. Our province has abundant peat resources.
