The Effect of Soil Conditioner Tebeigai on Peanut Yield and Soil pH Value

In order to study the effect of soil conditioner Tebeigai on peanut yield and the improvement effect of soil acidification, the application effect on peanut was tested. The results showed that compared with conventional fertilization, the application of soil conditioner Tebeigai could not only improve the main characteristics of peanut, but also significantly increase peanut yield, and improve soil acidification. The effect of 3 000 kg·hm^-2 Tebeigai was the best. Peanut yield was significantly higher than that of conventional fertilization, with an increase rate of 12.73%. The average number of full fruits per plant, full fruits per plant, fruit weight per plant and 100 fruit weight of peanut increased by 1.5, 1.6 percent point, 3.5 g and 7.8 g, respectively. At the same time, the soil pH value of cultivated layer after peanut harvest was significantly increased by 0.36, comparing with conventional fertilization.
