摘 要: | 目的]探讨粉垄栽培甘蔗的增产机制,为粉垄甘蔗生产提供理论依据。方法]以甘蔗品种桂糖43号为试验材料,研究粉垄耕作栽培和传统耕作栽培对甘蔗生长和产量的影响。结果]粉垄栽培有利于提高甘蔗的出苗率和分蘖率,粉垄甘蔗的出苗率比对照增加20.7%,分蘖率比对照增多25.4%;粉垄甘蔗的月生长速度比对照快6.4%~53.7%;蔗茎增粗7.7%~23.8%;粉垄蔗茎产量为191.25 t/hm~2,比对照增产18.2%。相关分析显示,有效茎数、茎长和茎径3个性状对蔗茎产量影响由大到小为茎长、茎径、有效茎数。结论]粉垄栽培是一项适宜甘蔗优质高产生产的新技术,可加以推广普及。

Abstract: | Objective] To discuss the yield increasing mechanism of sugarcane smash-ridging cultivation,and to provide theoretical foundation for the production of sugarcane smash-ridging cultivation.Method] With the sugarcane variety Guitang 43 as the test material,we researched the effects of smash-ridging and traditional tillage cultivation on growth and yield of sugarcane.Result] Smash-ridging cultivation enhanced the seedling emergence rate and tillering rate by 20.7% and 25.4%,respectively.The monthly growth rate and stalk diameter increased by 6.4%-53.7% and 7.7%-23.8%compared with the control.The cane yield was 191.25 t/hm2,which was 18.2% higher than the control.The results of correlation analysis indicated that the decreasing order of the importance of these factors to the cane yield was stalk height,stalk diameter,effective stalk.Conclusion] Smash-ridging cultivation is a new technique suitable for high yield and quality of sugarcane production,and can be vigorously extended. |
