云南高光效常规水稻品种株型研究
Study on Plant Type of Conventional Rice Varieties with High Light Efficiency in Yunnan Province
摘要
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.关键词
