摘要
采用四种植棉紫色土盆栽棉花和土植并析的方法,研究了土壤营养特性、棉株矿质营养元素组成和分布、棉花产量及其关系和产生原因。结果表明,氮、磷、钾、硼、钼、铜6元素是四川紫色土棉花栽培中最为必须并常在棉株体内显歉缺状态的营养成分,也是对棉花产量影响较大的土壤养分。
in this paper, the soil nutritional characterises, the component and distribution of mineral nutritional element of cotton plant, lint yield, the relationship between them and the reason caused have been studied by potting cotton with four types of purple soils in Sichuan, and tested the soil and cotton plant at the same time. The results indicated that the six elements-nitrogen,phosphorus, potassium, boron, molybdenum and copper are the most necessary in purple soils of Sichuan cotton belt,they are always some deficient in cotton plant, and are the soil nutrient of more contribution to cotton yield.
