【摘要】 以红地球、美人指、森田尼无核和无核早红葡萄为试材,进行三横梁"V"形架与单篱架栽培试验以对比产量、病害和产投比高低。结果表明,采用"V"形架的4个品种,栽后第2年平均666.7m2产量为761kg、第3年达1505kg,分别为单篱架栽培的2.43倍和1.8倍;采用"V"形架栽培可显著减轻果实日灼和白腐病、炭疽病的发生;建园后前3年的产投比为4.6 ~5.7∶1,显著高于单篱架栽培的2.5∶1。更多还原

【Abstract】 Trials with grape varieties ‘Red Globe’,‘Princess Finger’,‘Centenial Seedless’ and ‘Early Red Seedless’ revealed that the V-shape trellis helped the four varieties to increase their yields.The output averaged 11 415kg· ha-1 after two years and 22 575kg·ha-1 after three years,with 2.43 and 1.8 times increased than those cultured with single trellis,resp.Moreover,the V-shape trellis culture significantly decreased the occurrence of sunscald,white rot and anthracnose.The output-input ratio in the first three years after establishment of the orchard was 4.6~5.7∶7,markedly higher than that got by cultivation with single trellis(2.5∶1).更多还原
