前言你们的领导同志请我讲一讲与土壤碱化作斗争的方法。土壤碱化是灌溉地区农业生产中的严重恶果,但今天已创造了许多与它作斗争的方法。对碱化的斗争有两方面:即以前未起碱土地如何防止碱化(经常由于不正确的灌溉方法引起碱化)和与已碱化土地的抗碱斗争(清河农场的情况即属于这一种)。过去苏联每年因碱化而废弃的土地占总灌溉面积的百分之一至百分之二。所以在苏联已广泛地讨 Foreword Your leading comrades asked me to talk about ways to combat basification of the soil. Soil alkalination is a serious culprit in agricultural production in irrigated areas, but today many ways have been created to combat it. There are two aspects to the fight against alkalization: how to prevent alkalization (often caused by improper irrigation methods) and alkali resistance with already alkalized land Species). In the past, the amount of land abandoned by the Soviet Union in the past due to alkalization accounted for one to two percent of the total irrigated area. So in the Soviet Union has been widely discussed
