不同株行距、枝间距密度对克瑞森葡萄品质和产量的影响

Effects of Different Combinations of Plant, Row and Branch Spacing on Quality and Yield of Grape ‘Crimson’

为筛选出利于克瑞森葡萄科学栽培的株行距、枝间距密度组合,以解决生产中过度密植导致的高产低质低收问题。探究了3个株行距、枝间距密度互作对克瑞森葡萄品质和产量的影响效果。结果表明,株行距1.2 m±1.9 m与枝间距20~25 cm互作下,果实品质最优,产量最低;株行距0.8 m±1.7 m与枝间距10~15 cm互作下,果实产量最高,品质最差;株行距1.0 m±1.8 m分别与枝间距20~25 cm、15~20 cm互作,株行距1.2 m±1.9 m与枝间距15~20 cm互作,果实品质均较优,产量中等,适宜推广。

An attempt was made to screen out a density combination of plant, row and branch spacing which is suitable for cultivation of grape variety ‘Crimson’ to solve the problem of high yield and low quality resulted from planting at an excessively close spacing in production. Three combinations of plant, row and branch spacing were arranged to observe their effects on the quality and yield of the grape variety ‘Crimson’. The results showed that the grape was the highest in fruit quality and lowest in fruit yield when planted at a spacing of 1.2 m × 1.9 m and a branch spacing of 20-25 cm. The grape yielded the highest with the poorest quality when planted at a spacing of 0.8 m × 1.7 m and a branch spacing of 10-15 cm. The grape was moderate in yield and higher in fruit quality when planted at a spacing of 1.0 m × 1.8 m and a branch spacing of 20-25 cm or 15-20 cm, or at a spacing of 1.2 m × 1.9 m and a branch spacing of 15-20 cm, which were suitable for promotion.
