摘要
通过播期和密度2因子试验,分析得出水稻新品种黔优301在铜仁地区海拔600m左右获得高产的最佳栽培模式。播种期为4月中旬,密度在1．4万～1．5万窝／667m2,采用旱育浅植,加强田间肥水管理,综合防治病虫害,可获 600kg／667m2以上产量。
The optimal cultivated model for higher yield of Qianyou 301 is obtained by taking a field experiment witn different sowing time and density in Tongren prefecture with an elevation of 600 meters. The main cultivated measures for yield over 600 kg/667m^2 are that sowing on the middle ten days of April, 14000- 15000 holes/667m^2 of planting density, breeding seedling on upland nursery, shallow transplanting, rational management of manure and water, and controlling pest and diseases in field.
