豆科植物对土壤酸碱度的反应较敏感。本所柑桔园土壤偏酸,pH值5～5.5,历年来套种大豆,苗期均表现生长不良,植株矮小,叶小而皱缩;但施草木灰或石灰后,则立即好转。本试验的目的是探讨种植大豆的最适宜pH值,为大面积生产提供科学依据。一、试验材料与方法:本试验采用盆栽栽培。瓦盆高40厘米,内直径28厘米,面积0.55
Legumes are more sensitive to soil pH. The citrus orchard of our institute has partial acidity and pH value of 5 to 5.5. Over the years, intercropped soybean has poor growth, short plants and small folds; however, it is immediately improved after application of ash or lime. The purpose of this experiment is to explore the most suitable pH for planting soybean, providing a scientific basis for large-scale production. First, the test materials and methods: This experiment using potted cultivation. Tile basin height 40 cm, 28 cm in diameter, an area of 0.55
