晋南地区盐碱地棉花面积占山西省棉花总面积的5%。盐碱地植棉,突出的一个问题是苗期不易全苗保苗。晋南地区土壤盐分含量随水分变化而变化,可分为寒冬早春土壤盐分稳定期、春旱返盐期、6月高温积盐高峰期、夏末秋初脱盐期、秋末冬初返盐期。 根据盐碱地盐分变化特点和棉花的生长规律来探讨盐碱地棉花栽培技术措施,特别是保留全苗问题,对棉花增产具有现实意义.
The area of saline land in southern Shanxi accounted for 5% of the total area of cotton in Shanxi Province. Saline cotton planting, one of the prominent issue is not easy seedling seedling seedlings. The soil salinity content in Jinnan area varied with the change of soil moisture. It can be divided into stable soil salt period in early winter, salt return period in spring and drought period, salt accumulation peak in June, salt rejection period in late summer and early autumn, salt return period in late autumn and early winter. According to the characteristics of salinity and salt changes and cotton growth law to explore cotton and saline soil cultivation techniques and measures, especially to retain the whole seedling problems, the cotton yield is of practical significance.
