摘要:

果园生草作为重要的果园土壤管理措施之一,对果树生长发育和土壤肥力都有重要影响。以新疆南部阿克苏地区成林苹果园为对象,研究生草和清耕2种果园土壤管理方式对苹果园土壤肥力变化的影响。测定结果表明,生草能提高0~30 cm土层土壤有机质含量,且以表层土壤增加更为显著。生草试验后各处理0~30 cm土层土壤速效养分值均较试验前有不同程度的提高,但土层中全氮含量降低。生草后土壤全磷含量随土壤深度的增加而增加,0~10 cm土层全磷量为清耕>人工生草>自然生草,0~10 cm土层的全钾含量依次为人工生草>自然生草>清耕。各处理土壤全钾含量变化差异不明显。应重视对果园草的追肥,采取及时施肥措施来补充果园草生长消耗的养分。

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.
