摘要

灰土是源自火山灰的土壤,其特征是磷(P)浓度高。然而,由于土壤的物理化学性质,大部分P不容易被植物吸收。本研究的目的是评价液磷肥料对智利南部andiol型土壤中马铃薯作物生长和产量的影响。10种处理在苗期前和/或苗期后施用,包括单独施用或与黄腐酸和颗粒肥料联合施用的正磷酸盐或聚磷酸铵肥料;此外,还包括一个未受精的对照(T0)。在产量、茎总数和块茎大小方面存在显著差异。施用液肥导致叶片P含量水平相近,而施用聚磷酸铵和黄腐酸的茎数较高。此外,液磷可提高作物产量(38%)和大块茎比例(17%)。土壤中添加黄腐酸可增强正磷酸盐和多磷酸盐液肥对马铃薯的影响。

Evaluation of liquid phosphorus fertilizers and fulvic acids in a potato crop in an Andisol type soil
Andisols are soils derived from volcanic ash that are characterized by high concentrations of phosphorus (P). However, most of the P is not readily available for plant uptake due to the physical–chemical properties of the soils. The objective of this field study was to evaluate the effects of liquid P fertilizers on the plant growth and yield of a potato crop cultivated in Andisol type soil located in southern Chile. Ten treatments were applied pre- and/or postemergence, including orthophosphate- or ammonium polyphosphatebased fertilizers applied alone or in combination with fulvic acid and granular fertilizers; in addition, an unfertilized control (T0) was also included. Significant differences were found in terms of yield, total number of stems, and tuber size. The application of liquid fertilizers resulted in similar levels of foliar P content, while the number of stems was higher with the combined application of ammonium polyphosphate and fulvic acid. Furthermore, liquid P fertilizers increased crop yield (38%) and the proportion of large tubers (17%). The effects of orthophosphate and polyphosphate liquid fertilizers on potato were enhanced by the addition of fulvic acid to the soil.
