Research and Application of Pumping and Soil Improvement Techniques

Recently, the project of "Pumping and Adding Soil to Soil (Ground), Research and Application of Improved Technologies" undertaken by Haining City Fertilizer Station passed the appraisal of relevant experts of the province and city. The research project conducted a systematic investigation and study on the problems of many growth pumps such as rice and rapeseed grown during the reclamation and utilization of more than 7,000 mu of pump and soil (land) formed by the south drainage sea channel project. Understand the pump plus soil (ground) and the traditional Canadian soil, restructuring the field in the cause of soil nutrients, physical characteristics are significantly different. Through the application of early application and re-application of phosphate fertilizer, application of nitrogen and organic fertilizers, rational tillage and other technical measures, it is necessary to properly solve the crop growth obstacle problem of pump-pump plus soil preparation and increase the rice output from 300-350 kg / mu To nearly 500 kg / mu, close to the level of general farmland, rapeseed production reached, even more than the local general farmland production levels. The project has been in operation for three years since 2001 with a total area of ​​7055 mu of paddy rice, 1,200 mu of rapeseed and 1,300 mu of seedlings, covering a technical coverage of 70.5%.
