Soil Salinity Grading of Cotton Field in Coastal Saline Area
摘要
Abstract
Coastal saline soil within cotton cultivating areas in China is mainly distributed in the coastal low plain of Shandong, Hebei, Tianjin and north of Jiangsu Province. It has become one of the most important ecotypes of cotton field in China. On the basis of previous research and practice, the seasonal dynamics of soil salinity and its effect on cotton emergence, seedling establishment and lint yield were analyzed. To meet the demand of developing cotton production, the saline cotton fields were divided into four grades according to the total salt content in soil of 0 ~20 cm in spring (the middle and later ten days of March). They were desalinized non - saline soil ( <0.10% ), low salinity (0.10% ~0.25% ), moderate salinity (0.25% ~0.45% ) and high salinity soil (0.45% -0.80%). It was suggested that each type of saline cotton field should adopt pertinent and appropriate technical measures to improve the seedling establishment and cotton yield.关键词
