摘要
为有效提高防城港市防城区土地利用率,在该区种植上思县香糯是重要途径之一。为探索适应糯稻气象保障技术,在防城区开展香糯不同播种期的对比试验,结合试验区与原产地的平行气象观测资料,分析上思县香糯的生育周期、产量结构等生长特征及气象条件。结果表明,上思县香糯移栽到防城区等沿海地区种植是可行的。影响上思县香糯在防城区种植的主要气象灾害是暴雨、高温和台风;决定香糯产量的重要气象因子是昼夜温差和日照时数;香糯在防城区种植比杂交水稻早播种3~5 d为宜。
It is an important way to effectively improve land utilization rate to explore planting of Shangsi glutinous rice in Fangcheng District.In order to find meteorological support technology for glutinous rice adaptation,a comparison experiment was carried out in Fangcheng District in different sowing period of glutinous rice,and growth characteristics,yield structure and meteorological conditions of Shangsi glutinous rice were analyzed based on parallel meteorological observation data of test area and origin.Results showed that it was feasible to transplant Shangsi glutinous rice to Fangcheng District and other coastal areas.The main meteorological disasters affecting planting of Shangsi glutinous rice in Fangcheng District were rainstorm,high temperature and typhoon.Temperature difference between day and night and sunshine duration were important meteorological factors determining yield of sweet glutinous rice.Glutinous rice should be planted 3~5 d earlier than hybrid rice in Fangcheng District.
