| 摘 要： | 通过对安达市盐碱土改良进行研究,将一定量泥炭施入耕层(0～20cm);试验表明:泥炭在改良盐碱土的理化性质有明显效果:pH值降低;全盐量降低;土壤碱化度(ESP)下降;土壤总碱度(HCO3-与CO32-含量之和)降低;土壤容重下降;土壤有机质有所增加;该盐碱土区的农田作物的增产效果显著,能够促进植物养分吸收,刺激植物生长,提高抗逆性。

| Abstract: | Put certain amount of peat into plowed layer(0~20cm) to mend saline-alkaline soils in An Da City.The study shows that peat has apparent results on mending physiochemical property of saline-alkaline soils which including dropping PH value,total salt,exchangeable sodium percentage of soil,total alkalinity of soil(total content of HCO3-and CO32-),bulk density of soil and increasing soil organic matter.In addition,the peat can increase yield output of field crop apparently,speed up absorption of nourishment of plant,stimulate plant growth and improve Plant Tolerance to Environmental Stresses. |
