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.
