摘要:

本研究旨在探索云南省高光效水稻种植的理想株型模式,以促进水稻增产。选取低光效水稻品种‘楚梗27’(HP1)、‘台湾陆稻’(HP2)、‘AZUCENA’(HP3)、‘B3619C-7B-8-1- 4’(HP4)及高光效品种‘德农205’(HP5)、‘滇粳优1’(HP6)、‘滇屯502’(HP7)、‘云大107’(HP8)、‘滇瑞449’(HP9)为试验材料,开展水稻品种株型模式研究。试验采用单因素随机区组设计,以9个水稻品种为处理,每个处理均设置4个重复。按常规水稻的栽培方式进行水稻种植与水肥管理,在成熟期测定其与高光效相关的农艺性状。研究结果表明,云南省高光效品种的理想株型模式具备如下特征:株高为90~110 cm,穗长为22.0~25.3 cm,二次枝梗数为25.1~31.1个,剑叶叶基角为10.5~17.1°,剑叶开张角为11.7~17.4°,剑叶长为18.7~31.1 cm,剑叶宽为1.4~1.8 cm。该试验明确了云南高光效水稻的理想株型模式,为高光效水稻育种提供了理论依据。

Abstract:

This study aimed to explore an ideal plant type model for high light efficiency rice cultivation in Yunnan Province, thereby promoting rice yields. The experiment utilized low light efficiency rice varieties, namely 'Chujing 27' (HP1), 'Taiwan Upland Rice' (HP2), 'AZUCENA' (HP3), and 'B3619C-7B-8-1-4' (HP4), as well as high light efficiency rice varieties, specifically 'Denong 205' (HP5), 'Dianjingyou 1' (HP6), 'Diantun' 502 (HP7), 'Yunda 107' (HP8), and 'Dianrui 449' (HP9), as experimental materials to investigate rice variety plant type patterns. A single-factor randomized block design was employed, with 9 rice varieties constituting the treatments and 4 replicates per treatment. Rice planting, water, and fertilizer management were conducted according to conventional rice cultivation methods, and relevant agronomic traits for high light efficiency were measured at maturity. The results indicated that the ideal plant type pattern of high light efficiency varieties in Yunnan Province exhibited the following characteristics: a plant height ranging from 90 to 110 cm; a panicle length of 22.0 to 25.3 cm; the number of secondary branches of 25.1 to 31.1; a flag leaf base angle of 10.5 to 17.1°, a flag leaf opening angle of 11.7 to 17.4°, a flag leaf length of 18.7 to 31.1 cm, and a flag leaf width of 1.4 to 1.8 cm. This experiment has elucidated the ideal plant type pattern for high light efficiency rice in Yunnan, thus providing a theoretical foundation for breeding such rice varieties.
