| Abstract: | Guanglingxiangjing is a high-yield and good-quality rice variety, especially with very good taste. In order to explore the production potential of this variety, optimal cultivation techniques including sowing time, cultivation density , N dosage and water management in flowering stage were investigated. The results suggested that it was easier to obtain high-yield and good-quality using following cultivation techniques for this variety: suitable sowing date was about May 10; optimal transpling density was 0. 27-0. 33 million hills and 1. 5 million tillers per hectare; total N applied was around 240-255 kg per hectare, with the ratio of base fertilizer to seeding fertilizer was 7 : 3; intermission irrigation during grain filling was required, and the lowest soil water potential was about -15 kPa. |
| Keywords: | Guanglingxiangjing yield quality optimal cultivation |
