陵县盐碱地改良实验区,是我所在当地有关业务部门的协助下,于1973年建立起来的。至1981年已建立了面积达43万亩的陵西盐改实验区网。该地区由于旱、涝、盐、瘦等原因,粮棉产量低而不稳,粮食单产只有100多斤,棉花单产只有20—30斤,有的地块甚至颗粒无收,是历史上的一个老盐碱地区。这样的盐碱地在黄淮海平原很多,仅鲁西地区就有一千多万亩,为了较快的改良利用这些土地,现将我们采用的综合治理技术措施介绍于下。盐碱地是在多种因素综合影响下形成的。因此,要把旱、涝、盐、瘦作为一个统一的系统,统筹考虑。为此我们采用了农业措施与水利措施相结合、改良和利用相结合的方法,收到了显著的效果。一、建立扬灌扬排水利工程体系该地区土壤盐
Saline alkaline improvement experimental zone, is my local business department with the assistance of the establishment in 1973. To 1981 has established an area of 43 mu of Lingxi Salt to change the experimental zone network. Due to the drought, waterlogging, salt, lean and other reasons in the region, the output of grain and cotton is low and unstable. The yield of grain and grain is only 100 kilos and the yield of cotton is only 20-30 kilograms. Old saline area. This saline-alkali land in the Huang-Huai-Hai Plain many, only Luxi area has more than 10 million mu, in order to quickly improve the use of these lands, now we use the integrated management techniques introduced below. Saline is formed under the combined effect of many factors. Therefore, it is necessary to consider drought, waterlogging, salt and lean as a unified system. To this end, we adopted a combination of agricultural measures and water conservancy measures, a combination of improvement and utilization, and received significant results. First, the establishment of Yang Yang irrigation drainage system in the region soil salt
