一、前言我省盐碱十地带占相当大的面积,如安达、肇东等地。有的能长野生盐碱植物;有的赤土一片不生植物;在较经盐碱土上,虽然能够生长作物,但是产量很低,而播种的面积也受到局限。扩大盐碱地的利用,可从两方面着手,一方面是通过土壤改良,和防止士壤继续盐渍化;另一方面是通过生理生化的处理,提高作物抗盐力。提高作物的抗盐力,也就能够扩大播种面积和提高单位面积产量。我省在农业实践中,已提出盐碱地改 I. Preface Our province Salt and Pepper ten areas occupy a considerable area, such as Anda, Zhaodong and other places. Some can grow wild salina plants; some terra cotta plants; in more saline-alkali soil, although able to grow crops, but the yield is very low, and sown area is also limited. Expansion of the use of saline-alkali land can start from two aspects, on the one hand through soil improvement, and to prevent sodic soil salinization; the other hand, through physiological and biochemical treatment, improve the salt resistance of crops. Improve the salt resistance of crops, it will be able to expand sown area and increase yield per unit area. In the practice of agriculture in our province, we have proposed to reform the saline-alkali land
