摘要: 为明确甘蔗新品种云蔗05-51的高产高效栽培技术,加快该品种在生产上的大面积推广应用。于2014-2016年度在陇川弄门基地,对云蔗05-51以4个播种期和4个种植密度处理,布置二因素随机区组试验,研究播期和种植密度对‘云蔗05-51’的产量及其构成因素的影响。结果表明:播期对‘云蔗05-51’的茎径、有效茎数及蔗茎产量有显著影响,但对株高和锤度影响不显著;种植密度对‘云蔗05-51’的有效茎数、锤度和蔗茎产量有显著影响。蔗茎产量在1月20播种最高达到150.70t/hm2,过了1月20日后随着播期的推迟产量增减差别不大;在种植密度B1(150000芽/hm2)时蔗茎产量达到最高值127.25t/hm2,蔗茎产量随着种植密度的减少亦相应的减产。从播期和密度的交互效应来考虑‘云蔗05-51’最佳的播期和种植密度分别是1月20日播种,下种种植密度为B1(150000芽/hm2)。

Abstract: In order to clarify the high yield and high efficiency cultivation technology of new sugarcane variety Yunzhe 05 - 51, the wide application of this variety in production was accelerated. The effect of sowing date and planting density on the yield and its components of sugarcane variety was studied in Longchuan get base in 2014 - 2016 at four different seeding time and four planting density treatments. The results showed that the sowing date had a significant effect on the stem diameter, effective stem number and yield of cloud 05 - 51", but had no significant effect on plant height and brix. The planting density had a significant effect on brix and cane yield of" Yunzhe 05 - 51". The average yield of sugarcane was as high as 150.70 t / hm 2 in January 20, and the difference of yield increase or decrease with the postponement of sowing date after January 20. When planting density B1 ( 150000 bud / hm2 ), the yield of sugarcane reached the highest value of 127.25 / hm 2, and the yield of sugarcane stem decreased with the decrease of planting density. Considering the interaction effect of sowing date and density, the best sowing date and planting density of " Yunzhe 05 - 51" were sown on January 20, and the planting density was B1 ( 150000 bud / hm 2 ).
