我省盐碱地麦田,主要分布在予东、东北部的黄泛冲积平原区,面积约300万亩,占全省麦播面积的5％左右。这类麦田,受盐碱危害,单产一般收1百多斤,是我省的主要拉腿田。但在这些地区,如能采取有效措施,仍可获得增产,有很大增产潜力。盐碱土,有的含大量可溶性盐,如氯化钠、硫酸钠等。有的含有可溶性碱,如碳酸钠、碳酸氢钠等,使土壤形成了“碱、湿、凉、板、薄”的状况。严重影响小麦的生长。特别是氯离子的存在,直接损害了细胞组织及其功能,腐蚀毒害了根系,引起大量死苗。而过多的钠
The saline-land wheat fields in our province are mainly distributed in the Yellow-pan alluvial plain area to the east and northeast of China, covering an area of about 3 million mu, accounting for about 5% of the sowing area of the province. This type of wheat fields, harmed by salt and alkali, yield generally receives more than one hundred kilos, is the main leg of the province. However, if effective measures can be taken in these areas, it will still be possible to increase production and increase production potential. Saline soil, some with a large number of soluble salts, such as sodium chloride, sodium sulfate. Some contain soluble alkali, such as sodium carbonate, sodium bicarbonate, the soil formed a “alkali, wet, cool, plate, thin” status. Seriously affect the growth of wheat. In particular, the presence of chloride ions, directly damage the cell organization and its function, corrosion poisoned the root system, causing a large number of dead seedlings. And too much sodium
