浙江省直播稻技术发展过程回顾与分析评价

Review and Evaluation of Rice Direct Seeding Technology in Zhejiang Province

回顾总结了浙江省20多年直播稻发展的三个阶段,分析得出直播稻快速发展的主要技术优势为省工省力省本明显、产量不低、技术配套,并提出了其发展过程中还存在的三大技术难题。从技术本身对直播稻进行了综合评价,认为直播稻符合社会发展要求,是当前一项高产高效技术,仍是今后我国水稻生产重要的栽培方式,可以通过加快机械穴直播的研究来改进和完善直播稻技术。

The author reviewed the three stages development of rice direct seeding technology in more than 20 years,analysised the main technical advantages for the obvious labor saving,stable yields,technical support of rice direct seeding,and put forward three major technical problems existing in the production process in Zhejiang Province.Comprehensive evaluation showed that direct seed-ing rice is a high yield and high efficiency techniques comply with the reguirements of social development,and an important way of future rice cultivation in China.In the future,the technology of rice direct seeding must be improved by speeding up the research on mechanical hole direct sowing.
