重度盐碱地水稻控盐高产栽培技术研究

Study on Salt-controlling Cultivation Technology of Rice in Severely Saline Soil

盐碱地种植水稻一直是一个难题,特别是在盐分较大的土壤条件下成功种植水稻更是一个世界性的难题。我国是一个盐碱地较重的国家,吉林省镇赉县又是盐碱地集中的地区,其土壤盐分含量高、理化性质差、养分贫瘠、土质黏重,通透性差。经过多年的试验,采用各种手段成功解决了在高盐分含量的土壤上种植水稻的新方法。其主要控盐栽培技术就是在坚持运用耐盐碱品种和坚持泡田洗盐的前提下,稻田深翻耕、客土改土、培育壮苗、科学施用化肥、增施有机肥、及时防治病虫草害等关键栽培技术,以达到高盐分条件下夺取水稻高产的目的。

It is difficult to grow rice in saline land and also a worldwide problem to plant rice successfully in severely saline soil.China has a large saline area and Zhenlai county of Jilin is concentrated with saline land where the soil has the characteristics of high salt content,poor physical and chemical properties,poor nutrient,heavy clay and poor permeability.After years of experiments,new technologies were developed for growing rice in severely saline soil.These salt-controlling cultivation technologies for rice included using salt-tolerant varieties,washing salt by soaking soil,plowing rice fields deeply,improving saline soil with foreign soil,using healthy seedlings,using fertilizer scientifically with more organic manure,preventing and controlling pests,diseases and weeds in time,etc.
