摘要：

为了实现山西水稻生产中高产、优质、高效、生态、安全的目标,推动山西水稻产业的发展,该研究以‘晋稻12号’为试验材料,采用随机区组设计方法,比较分析了不同的施肥方案与水分管理方式对其农艺性状的影响。结果表明：不同栽插密度与追肥比例处理对水稻生育进程均影响不大,但对其产量性状有一定的影响,其中,追肥比例为A2时,其增产效果最佳;此外,追肥比例为A2,栽插密度与施肥量分别为D1、N3时,其增产效果最优;在栽插密度D1,施肥比例A2,施肥量N3的配比处理下,进一步优化了灌溉方式,集成的新模式与原栽培方式相比,其增产率可达17.9 %。综合以上试验结果,本研究总结提出了一套‘晋稻12’的高产高效栽培技术,其兼具节水、提质、增抗等优点,为深入开展水稻栽培技术方面的研究奠定了良好的基础。

Abstract:

To realize the target of high yield, fine quality, high efficiency, eco-friendly and safe rice production in Shanxi, and promote the development of rice industry, the authors selected ‘Jindao 12’ as the test material, analyzed the effects of different fertilization schemes and water management on its agronomic characters with the randomized blocks design. The results showed that different transplanting densities and ratios of topdressing had no significant effect on the growth process of rice, while they had certain effect on the yield trait. When the ratio of topdressing was A2, the yield increasing benefit was the best. In addition, the yield increasing effect was also the best when the ratio of topdressing, transplanting density, fertilization was A2, D1, N3, respectively. Under the treatment of transplanting density D1, ratio of topdressing A2 and fertilization N3, the irrigation method was further optimized and the new integrated mode could increase the yield by 17.9%. Based on the above experimental results, the study proposed a new cultivation mode of high-yield and high-efficiency for ‘Jindao 12’, which had the advantages of water saving, quality improving and resistance enhancing. This study could provide a foundation for further research on rice cultivation technique.
