我省有内陆盐碱地700余万亩,建国以来党和国家领导人民,对盐碱地进行了综合治理,植树造林就是其中重要措施之一。在内陆盐碱地造林工作中,查清不同树种的抗盐能力,进而根据宜林地含盐量高低选择相适宜的树种,对提高盐碱地造林质量,加快绿化速度有重要意义。为此,在内陆盐碱地,先后调查了衡水、邢台、邯郸三个地区的10个县,13个大队和7个林场,涉及到18个树种,共打土壤剖面47个,取土样188个。经过野外调查和室内化验工作,对我省内陆盐碱地区常用造林树种的抗盐能力,得到了较为可靠的数据,现总结如下:
In our province, there are more than 700 million mu of inland saline-alkali land. Since the founding of the People’s Republic of China, the party and state leaders have conducted comprehensive management of the saline-alkali land. Afforestation is one of the important measures. In the inland saline-alkali afforestation work, it is important to find out the salt tolerance of different tree species, and then select the suitable tree species according to the salinity level of the saline-alkali soil, which can improve the afforestation quality and speed up the afforestation speed of saline-alkali soil. To this end, inland salinity, has investigated 10 counties, 13 brigades and 7 forest farms in three areas of Hengshui, Xingtai, Handan, involving 18 species of trees, playing a total of 47 soil profiles, taking 188 soil samples . After field investigation and indoor laboratory work, we have obtained more reliable data on the salt resistance of common afforestation tree species in the inland saline-alkali areas in our province, and are summarized as follows:
