机械平茬对宿根蔗蔗蔸及产量的影响
Effects of Mechanical Stubble Shaving on Stubble and Yield of Ratoon Sugarcane
摘要
Abstract
In order to understand the effect of mechanical stubble shaving on stubble and yield of ratoon sugarcane,mechanical stubble shaving experiments were carried out on Zhongzhe 3 in Changping Township,Fusui County and Guitang 44 in Chengxiang Township,Wuming County,Guangxi.The change of the stubble,yield performance of ratoon sugarcane and the influence on the stubble of the next ratoon sugarcane were investigated by mechanical stubble shaving treatment with no stubble shaving as the control(CK).The results showed that the underground stem length of 1-year and 2-year ratoon sugarcane treated with mechanical stubble shaving for Zhongzhe 3 was 13.70 and 11.64 cm,and the underground bud number was 7.09 and 6.40,respectively,which were extremely significantly lower than the CK.The underground stem length and underground bud number of 1-year ratoon sugarcane treated with mechanical stubble shaving for Guitang 44 were 11.86 cm and 7.83,which were also extremely significantly lower than the CK.After harvesting,the underground stem length of next ratoon sugarcane with mechanical stubble shaving for Guitang 44 was 17.61 cm,which was significantly higher than that in CK.The underground bud number was 9.17,which was 41.73%higher than in CK,and also significantly higher than in CK.There were no significant differences in underground stem weight,root fresh weight and root-stem ratio compared with CK.The number of seedlings emerging,the number of seedlings at tillering stage,the number of effective stems and the yield in 1-year and 2-year ratoon sugarcane after mechanical stubble shaving treatment for Zhongzhe 3;the number of millable canes in 1-year ratoon sugarcane after mechanical stubble shaving treatment for Guitang 44 were all significantly higher than the CK;the yield of sugarcane increased by 7.98%-11.16%.Mechanical stubble removed the above and upper buds,promoted the germination and growth of the middle and lower buds,increased the millable canes,increased the yield of sugarcane,delayed the upward movement of the position of sugarcane stump,increased the number of underground buds of the next ratoon stubble,and extended the years of ratoon.关键词
