引言【目的】研究生物有机肥对库尔勒香梨园土壤肥力的影响。【方法】选取代表性试验地,进行化学肥料、生物有机肥料、化肥与生物有机肥混施以及对照处理并进行分析。【结果】(1)以生物有机肥处理下,容重下降比例最高,并呈显著性差异,其次为生物有机肥与化学肥料配施。(2)土壤含水量与容重呈反相关,比对照处理分别增加10.79%。生物有机肥处理下,土壤物理性质改善较高,容中下降,含水量增加。(3)碱解氮的
Introduction 【Objective】 To study the effect of bio-organic fertilizer on soil fertility of fragrant pear orchard in Korla. 【Method】 Selected representative test sites were selected for chemical fertilizers, bio-organic fertilizers, chemical fertilizers and bio-organic fertilizers and the control treatments were carried out and analyzed. 【Result】 (1) Under the treatment of bio-organic fertilizer, the bulk density decreased the highest, with significant difference, followed by bio-organic fertilizer and chemical fertilizer. (2) The soil water content is negatively correlated with the bulk density, which is increased by 10.79% compared with the control. Under the treatment of bio-organic fertilizer, the physical properties of soils improved a lot, the capacity decreased and the water content increased. (3) alkaline hydrolysis of nitrogen
