Other Abstract通过大田和盆栽试验研究了四川主要植棉紫色土的水分特性及其与棉花生长的关系,结果表明田间沙溪庙组土壤因其入渗性强和地形平缓、土层深厚,表现出水分过多;遂宁组土壤入渗能力极差,土壤有效水特别是非正常生育有效水极少,易显“旱象”;而城墙岩群、蓬莱镇组土壤则具有适宜的土壤水分条件。盆栽下不同土壤的物理性质趋于近似,人工控制供水一致的条件下,不同土壤的棉花产量无显著差异。; The moisture charactertistics of 4 cotton-planting purple soils in Sichuan and their influence on cotton growth were researched by both the field investigation and the pot edperiment.In case of field there was a wide range difference of soil moisture properties among 4 soils.The Shaqi Miao Group(J25)presented a surplus of moisture due to the combining effect of its stronger percolation and the gentle slope terrain and thicker soil mass.The Suining Group(J3s)had much weaker percolation,and its available water for non-normal growth which played an important role in liable to drought was lower.Therefore,"signs of Draught "easily appeared on it.The Chengqiang Yan Group(K1Cg)and the Penglai Zhen Graup(J3p),however, had a suitable condition of soil moisture,especlally the latter.In pot culture circumstances,various soils tended to be similar in soil physical properties including soil moisture characteristics.The tiny difference of moisture properties were removed by the artificial control of water supply.The result showed that no significant difference of cotton field existed among 4 soils.And it has been further proved that there was a close relationship between the moisture properties and the cotton growth under conditions of field.
