Abstract:
In order to improve the soil fertility of saline-alkali soil in Songnen plain and increase local crop yield, the thechnical theory of improving saline-alkali land with biochar is proposed. This experiment adopted randomized block design with different dosages of biochar, and the soil moisture permeability and soybean yield were researched. The results showed that biochar could increase the soil moisture permeability. The initial infiltration rate, average penetration rate, steady infiltration rate, cumulative infiltration amount, and saturated permeability coefficient in treatment Y3 were 23.75, 28.46, 23.69, 24.42 and 24.79 times of CK respectively. The biochar increased the content of organic matter, available phosphorus, available potassium, total nitrogen, total phosphorus and total potassium. The soybean yield reached the maximum value 3.17 g per plant in Y3, and was 2.22 times of CK.
