该项研究宗旨是探索雷州半岛杂交玉米高产制种的可行性及其配套制种技术．经过两年三造的试验研究，其主要经济技术指标达到预期效果．累计面积２６ ．９ 亩．组合为南试８４７ ，加权平均亩产量为２３７ ．１ ｋｇ，最高亩产３００．１ ｋｇ．根据研究结果，本项目初步总结出了南试８４７ 组合杂交制种配套技术，为指导玉米制种提供了理论依据和实践经验．
The purpose of this research is to explore the feasibility of breeding high-yielding hybrid corn in Leizhou Peninsula and its matching seed production techniques. After two years of three pilot studies, its main economic and technical indicators have achieved the desired results. The total area of 26. 9 acres. Combination of the South Test 847, the weighted average yield of 237 acres. 1 kg, the highest yield 300.1 kg. According to the results of the study, the project initially summed up the Nantong 847 hybrid hybrid seed production technology, which provided theoretical basis and practical experience for guiding the seed production of corn.
