Abstract:

As one of the important soil managements, growing grass have great effects on the growth of the fruit tree and the soil fertility. The paper based on the apple orchard of Aksu area in the southern Xinjiang and studied the soil fertility changes under the growing grass and Qinggeng orchard soil managements. The results indicated that the growing grass can improve 0-30 cm soil organic matter content of the soil and the top soil increased more significant. The available nutrients had different degrees of improvement in 0-30 cm soil, but the quantity of the N content reduced in the 0-30 cm soil. The quantity of the soil phosphorus content increased with the soil depth and the content in 0-10 cm was Qinggeng>artificial grass>grass. The total potassium content was artificial grass>grass>Qinggeng. The soil total potassium content changes have no obvious differences. More attention should be given to the grass fertilizer and supple the consumption of nutrients for the orchard grass growing.
