1957年的6—9月间,我们能有机会到国营淮海农场进行生产实习,初步接触到盐渍土上作物栽培的一些特点,这些特点突出的表现在土壤盐份含量严重的制约着作物的生长发育,因而使得作物的单位面积产量,一般都还停留在较低的水平。棉花,是比较耐盐而且是经济价值很高的作物,故在盐渍土上有着相当广泛的栽培,以往在这方面的研究和报导很多;但是盐渍土上棉花的不同前作对棉花的出苗、生长究竟存在着什么表像和相互影响,似乎还见到很少。国营淮海农场位於江苏省射阳县黄海之滨,全年无霜期在180天以上,每年的四月下旬以前气温不甚稳定,以后即不稳定上升到12℃以上。全年雨量约为800mm左右,且大半集中於7—8
From June to September 1957, we had the opportunity to conduct internship at the state-run Huaihai Farm and initially touched on some characteristics of crop cultivation on salty soil. These characteristics are highlighted by the serious limitation of salt content in the soil Growth and development, thus making the crop yield per unit area, generally still remain at a lower level. Cotton, which is relatively salt-tolerant and is a crop with high economic value, has a wide range of cultivation on saline soils. In the past, there were many studies and reports on this topic. However, , What exactly does it seem to grow and how it interacts with each other? The state-run Huaihai Farm is located on the coast of the Yellow Sea in Sheyang County, Jiangsu Province. The annual frost-free period lasts for 180 days or more. The temperature is not stable before the end of April each year, and then rises unstable above 12 ℃ in the future. Annual rainfall is about 800mm, and the majority concentrated in 7-8
