| 摘 要： | 目的]明确伊犁河谷新稻46号的栽培密度,为提高其产量提供理论依据。方法]采用小区试验研究6个插秧密度水平对新稻46号生育期、分蘖动态、经济性状、抗性和产量的影响。结果]行距相同情况下,株距越大越有利于分蘖的形成。产量在10 500 kg/hm2以上的密度处理有30 cm×10 cm、30 cm×12 cm、25 cm×12 cm和25 cm×14 cm,其中25 cm×12 cm密度处理行距相对较窄,通风相对较差,抗病性较差;30 cm×10 cm、30 cm×12 cm和25 cm×14 cm密度处理水稻的群体结构与个体能得到很好的协调,有利于夺取高产。结论]机插条件下,伊犁河谷新稻46号适宜的栽培密度(行距×株距)为30 cm×10 cm、30 cm×12 cm和25 cm×14 cm。

Cultivation Density of Xindao 46 in Yili Valley |

| Abstract: | Objective] To clear cultivation density of Xindao 46 in Yili valley and provide theoretical basis for improving its yield.Method]We studied effects of six planting densities on growth period,tillering dynamics,economic characters,resistance and yield of Xindao 46 by plot experiment.Result] Under the same spacing between rows,the larger spacing in the rows was helpful for the formation of tillering.Four planting densities like 30 cm × 10 cm,30 cm× 12 cm,25 cm× 12 cm and 25 cm× 14 cm had more than 10 500 kg/hm2 of yield,among them the planting density of 25 cm× 12 cm had smaller spacing between rows,worse aeration and worse resistance,while the planting densities like 30 cm × 10 cm,30 cm × 12 cm and 25 cm × 14 cm had good coordination between population structure and individuals of rice and was benefit for high yield.Conclusion] Under the machine conditions,the suitable planting densities (spacing between rows × spacing in the rows) of Xindao 46 in Yili valley are 30 cm × 10 cm,30 cm × 12 cm and 25 cm× 14 cm. |
