品种、播期及密度对红麻生长发育及产量性状的影响
Effects of different varieties, sowing dates, and density on the growth and yield traits of kenaf
摘要
Abstract
[ Objective ]This research aimed to provide technical support and theoretical basis for high-yield cultivation of kenaf (Hibiscus cannabilus L.) fiber and seeds. [Method]At the scientific research construction base in Guangxi Academy of Agricultural Sciences in 2009, the kenaf varieties Fuhong 991, Fuhong 952, and Fuhonghang 992 were used as test materials. The three testing factors of variety, sowing date, and density were set and then repeated for 3 times to examine the whole growth period, plant height, stem diameter, skin thickness, skin weight, seed yield, and other relevant indexes. [Result]The effects of testing factors on the kenaf growth and yield traits were ordered as follows: sowing date> density > varieties. When the sowing date was set at May 11th, higher fiber and usable seed yields were obtained. When the planting density was between 225,000-270,000 seedlings/ha, higher fiber and seed yields were acquired. Differences between the fiber and seed yield of the 3 kenaf varieties were not significant. The fiber yield was significantly positively correlated with 8 kenaf indicators, such as plant height, stem diameter, skin thickness, etc., and the seed yield was significantly positively correlated with 11 kenaf indicators, such as plant height, stem diameter, ripe fruit number, etc. [Conclusion]Within a certain time frame, proper early kenaf sowing could result in higher fiber and seed yields, but when sowing occurred during the late sowing period of July, the seed yield could also be ideal. During the actual production of kenaf, the sowing date, density, and variety should be coordinated according to targeted comprehensive consideration. On the other hand, when selecting new breeding kenaf varieties, the plant height, stem diameter, skin thickness , and other relevant indicators could be selected as the main investigative indicators.关键词
