北方水稻直播栽培的农艺问题与对策
Agronomic Problems and Countermeasures of North Rice in Direct Seeding Cultivation
摘要
Abstract
The agronomic problems related to direct seeding in north China on temperature and light characteristic, ecological and climatic conditions, cropping system and cultivation were amalysed. We consider that the essential difference between direct seeding and seedling transplantation exists in growth period, growing process and filling stage. Panicle number type and both panicle and grain number type are more appropriate for yield formation. Continuous cropping should be achieved by the appropriate varieties. Cold tolerance, photosensitivity and tilling potential should be the reference in breeding and variety selection, as well as panicle type with more primary branch number. Four principles should be followed as seeding cultivation management, increasing the seeding rate, improving the early management, enhancing the chemical management and postponing harvest. Some scientific problems have been discussed and summarized in this paper which should be further studied about direct seeding cultivation in north China.关键词
