Abstract

The aim of this study was to investigate the proportion of spray liquid applied in a typical application that was deposited on the soil surface below the crop. This part of the spray is not only an application loss, but it also constitutes a primary source to leaching. The investigation was carried out during 1999-2001 in sugar beets and potatoes. Applications were carried out at approximate intervals of 10 days during the whole growing season in both crops, which were grown in rows. The results show that a high proportion of the spray liquid reaches the soil below the crop during applications at early growth stages, which correspond with stages when weed control is practised. At later growth stages soil deposition declined and reached values below 10-15% of the applied dose in sugar beet (GS 39) and 5-10% in potatoes (GS 59-79).
在生长季节施用后,在甜菜和土豆下面的土壤上喷洒液体
本研究的目的是调查喷洒液体的比例,在一个典型的应用程序,是沉积在作物下面的土壤表面。这部分喷淋不仅是一种应用损失,而且也是淋滤的主要来源。这项调查是在1999年至2001年期间对甜菜和土豆进行的。在两种作物的整个生长季节中,每隔大约10天施用一次,这两种作物都是成行种植的。结果表明,在生长早期施用时,喷雾液到达作物下方土壤的比例很高,这与实施杂草控制的阶段相对应。在生长后期,土壤沉积量下降,甜菜(GS 39)和马铃薯(GS 59-79)的土壤沉积量分别低于施用剂量的10-15%和5-10%。
