| 摘 要： | 以盆栽试验的方法研究应用生物型煤粉煤灰改良辽河平原北部碱土，结果表明，施用生物型煤粉煤灰后在提高小麦出苗率、增加产量的同时，土壤水溶性盐分含量、组成和透水性发生了明显的变化，ＣＯ_２－~３和ＨＣＯ_３~－降，Ｃａ２＋和ＳＯ_２－~４上升，在同一吸力下，施用改良剂的土壤释水量明显增加，土壤水渗透速度也大幅度提高．生物型煤粉煤灰用量以１％～２％为宜．

| Abstract: | The results of the pot experiments, which using bio - briquette to amend alkali - soil of the northern of Liaohe plain, showed that bio - briquette could increase wheat emergence rate, yield. At the same time, there were obvious changes in contents of water - soluble ions, components, and the permeability of soil water. The contents of CO_2-~3 and HCO_3~- were decreased, and of Ca2 and SO_2-~4 were increased. The amount of waterreleased from the soil amended with bio - briquette increased at the same suction compared with control, and so the water penetration rate . According to the pot ex- periments, the appropriate amount for bio - briquette application was 1% -2%. |
