盐碱地对作物的危害有轻有重。有一些作物高度耐盐,如柽柳能在含盐量高达1.0—2.4％的土壤里良好生长,罗布麻在50—100厘米深处的土壤含盐量(以氯盐和硫酸盐为主)不高于1.0％左右,不论表层盐分轻重(有时达到10％)均可自然生长。所以,掌握了解土壤含盐量和作物的耐盐极限,根据当地土壤盐碱化程度,选种适宜的耐盐作物,达到增产增收,是开发利用盐碱地的一项重要措施。
Saline alkali harm to the crop light and heavy. Some crops are highly salt-tolerant, such as tamarisk that grows well in soils with salinities of up to 1.0-2.4%, and soil salinities (mainly chloride and sulfate) in the depths of 50-100 cm Higher than about 1.0%, regardless of surface salinity (sometimes up to 10%) can grow naturally. Therefore, it is an important measure to develop the use of saline-alkali soil to master the salt tolerance of soils and the limit of salt tolerance of crops. According to the degree of salinization of the soil in the area, the appropriate salt-tolerant crops are selected to increase yield and income.
