通过土壤普查,摸清了全疆现有4,100万亩耕地中,需要改良的低产地约1,200万亩,其中盐碱地约为500万亩(连轻度盐碱化的共为900万亩),约占耕地面积的12.2%,成为发展农业生产的主要障碍.自治区要求在二年内将此全部盐碱地改造过来,并防止次生盐碱化的再生,使低产变高产,高产更高产,以促进农业生产的不断跃进.根据中央对防治灌区盐碱土的指示,是:“以防为主,防治并重……”的方针,除了对现有的改良方法进行研究、总结、提高和推广,以消减现有的次生盐碱化土壤外,对如何采取积极措施预防土壤的次生盐碱化,以永远摆脱盐碱的威胁,应该给予足够的重视.
Through the soil survey, found that 41 million mu of arable land in Xinjiang, the need to improve the low-yielding area of about 1,200 acres, of which about 500 acres of saline-alkali land (with a mild salinization of a total of 900 acres), about Accounting for 12.2% of the arable land area, becoming the major obstacle to the development of agricultural production. The autonomous region requires that all the saline-alkali lands be rebuilt within two years and the secondary salinization should be prevented from being regenerated. As a result, low-yielding, high-yielding and high- According to the instructions of the central government to control saline-alkali soil in the irrigation area, the principle of “putting prevention first and prevention and treatment equal ... ...”, in addition to conducting research, summarizing, improving and popularizing existing methods of improvement so as to reduce existing Of the secondary salinization of soil, how to take active measures to prevent the secondary salinization of soil, so as to get rid of the threat of salinity, we should pay enough attention.
