南方巨峰葡萄产量和品质性状与负载量间关系的研究（Ⅱ）每平方米架面留结果母枝量的探讨

The Number of Remaining Bearing Branches on Straining Areas Per Square Meter after Winter Pruning.

１９８６～１９８８年对５年生巨峰葡萄连续３ａ的试验结果表明：每平方米架面留５根结果母枝，产量为３．５４～３．６５ｋｇ，６６７ｍ￣２产量为２０２７～２４３４ｋｇ，单穗平均重１９３．３０ｇ，平均单果粒重６．６７ｇ。其可溶性固形物为１２．７６％～１３．４９％，着色度在７０．６％～６３．７％，固酸比约为１５．１３％。

The experiment was conducted for three years(1986～1988), inorder to determine the load index of KyohO grape with five years of age.The experiments showed that the best number of remaining bearing brancheson the straning areas per square meter after winter pruning should be 5branches.With this number of grape garden, the yield per plant could beobtained with 3.54～3.65 kg,cluster weight with l93.30g’berry weight with6.67 g’rate of soluble solids with l2,76%～13.49%,color index with 70.6%～63.7%and acidity with 15.13%。
