滴灌条件下不同基因型甘蔗高产性状及水分利用效率

在大田滴灌条件下，研究15个不同基因型甘蔗高产性状表现及水分利用特性，旨在为甘蔗新品种的推广应用及高产栽培提供参考。结果表明：采用滴灌栽培能显著增加甘蔗产量，提高蔗糖分；GT97—69、GT02—833、GT02—770等13个品种（系）产量高于CKl，且产量在120t／hm2以上，其产量性状表现为株高273—357cm，茎径2．47～3．32cm，有效茎71990～97775条／hm2，农田总供水利用效率删uEa）为64．40-83．71kg/mm·hm2。...

Under field drip irrigation, we studied the high yield properties expression and water use character of 15 different genotypes sugarcane, and aimed to provide reference for popularization application and high yielding cultivation of new varieties. The results showed that yield increased and sucrose increased significantly with the application of drip irrigation cultivation; the yield of 13 varieties such as GT97-69,GT02-833 and GT02-770 were higher than CK1, and the yield was above 120 t/hm2; their yield properties expression that the plant height was from 273 to 357 cm , the stalk diameter was from 2.47 to 3.32 cm and effectiv
