果蔗新品种桂果蔗1号引种品比试验

Introduction and Comparison Experiment of a New Chewing Cane Variety Guiguozhe1

以横县果蔗当家品种拔地拉(俗称黑皮果蔗)为对照种,对桂果蔗1号进行2年多点比较试验。试验结果:桂果蔗1号株高332.0cm,比对照种312.0cm高20.0cm;茎径为3.89cm,比对照种的3.87cm大0.02cm;667.7m^2产蔗13223kg,比对照种的11589kg增产14.10%;商品蔗产量12949.6kg,比对照种的10438.4kg增产24.06%,商品蔗率高达97.93%;其节间长度较长,商品性较佳,长度8.0~13.9cm的节间占总数的82.29%,拔地拉只有70.47%,对商品性影响较大的极短节≤5.9cm中只有0.87%,拔地拉高达4.19%;植株上中下大小均匀,茎粗下、中部相差0.24cm,上、中部相差0.06cm,拔地拉上部较小,表现出早衰现象;蔗糖分略高于拔地拉;产值较高,达19305.0元/hm^2,比拔地拉的14945.9元/hm^2增收29.17%,差异达极显著水平。结论:桂果蔗1号农艺性状、商品性状、产值等均优于拔地拉,可在横县进行大面积推广应用。

Two-year multi-1 ocation experiments were carried out for evaluating of chewing cane variety Guiguozhel compared with variety Badila as control in Heng County. The results showed that Guiguozhel had a height of 332.0 cm, diameter of 3.89 cm, cane yield of 13223 kg/667.7m^2, and commercial cane yield of 12949.6 kg/667.7m^2, increased by 20.0 cm, 0.02 cm, 14.10%, and 24.06% than that of Badila, respectively. The commercial cane rate of Guiguozhel was up to 97.93%. Guiguozhel＇s internode length was longer, better commercial internode with the length between 8.0 cm and 13.9 cm, which accounted for 82.29%, but only 70.47% in Badila. Internode of Guiguozhel that was shorter than 5.9cm was only 0.87%, whereas Badila was 4.19%. Guiguozhel had a uniform stalk size from top to bottom, and there was 0.24 cm difference between bottom and middle, and 0.06 cm difference between top and middle. Badila had a smaller top with premature senility phenomenon. Guiguozhel had a higher output value of 19305 yuan （RMB）/ha, and increased by 29.17%, compared with 14945.9 yuan （RMB）/ha of Badila. Guiguozhel had better agronomic and commercial traits and output value than that of Badila, could be widely extended in Heng county.
