保护地桃树土壤盐类积聚引起的土壤盐渍化是保护地桃树普遍存在的突出的问题。盐渍化不仅降低了土壤的肥力、缓冲能力和有效微生物的比例,而且对桃树造成许多不利影响,造成植株发育不良,甚至死亡。一、造成保护地土壤盐渍化的原因。保护地无降雨淋溶作用,矿物离子、盐类物质在土壤表层积聚;施肥超量引起,如肥料的成分及质量对土壤浓
Soil salinization caused by the accumulation of salt in the protected peach tree soil is a prominent problem in the perennial protected peach tree. Salinization not only reduces soil fertility, buffering capacity and the ratio of effective microorganisms, but also causes many adverse effects on the peach tree, resulting in poor plant growth and even death. First, the causes of soil salinization of protected areas. Protection of the land without rainfall leaching, mineral ions, salt accumulation in the surface of the soil; fertilization caused by excess, such as fertilizer composition and quality of the soil concentration
