不同播期对苦荞生长发育及产量和品质的影响
|
摘要
为明确苦荞秋季的适宜播期,本试验以‘黔苦6号’为试验材料,设置不同的播期处理,研究了播期对苦荞农艺性状、品质及产量的影响。结果表明:播期对苦荞的生长发育及产量和品质均有一定影响。随播期推迟,苦荞各生育阶段相应推迟,全生育期增加。农艺性状、蛋白质含量、淀粉含量、产量及其构成因子随播期的推迟呈先增后降趋势。产量和农艺性状、蛋白质含量、淀粉含量、单株粒数、单株粒重呈极显著正相关关系。‘黔苦6号’在贵州毕节地区秋播的适宜时间为8月28日左右,此播期处理更有利于苦荞的生长发育及优质高产栽培。该研究结果为进一步研究苦荞秋播的适宜播期及其优质高产栽培提供了理论依据。
In o rder to clarify the suitable sowing date of tartary buckwheat in autumn, this experiment used'Qianku No.6' as the experimental material and set different sowing date treatments to study the effects of sowing date on the agronomic traits, quality and yield of tartary buckwheat. The results showed that the sowing date had certain effects on the growth, quality and yield of tartary buckwheat. With the delay of sowing date, the growth stages of tartary buckwheat were postponed correspondingly, and the whole growth period increased. Agronomic traits, protein content, starch content and yield and their related factors increased first and then decreased with the delay of sowing date. There was a significant positive correlation between yield and agronomic traits, protein content, starch content, number of grains per plant, and grain weight per plant. The suitable time for 'Qianku No.6'in autumn in Guizhou Bijie area is about August 28 th. This sowing period is more conducive to the growth and development of tartary buckwheat and high-quality and high-yield cultivation. The results of this study could provide theoretical reference for further study on the suitable sowing date of autumn sowing of tartary buckwheat and its high-quality and high-yield cultivation.
